I Updated My iPhone to Net10 & Straight Talk Carrier Update TFW 15.7 and Now My 4G Is Only 3G!


UPDATE: December 9 2014
I have created a guide that explains how to downgrade from TFW 15.7 to TFW 15.6. See How To Change Your iPhone’s Carrier from TFW 15.7 back to TFW 15.6 for Straight Talk and Net10 Customers If you decide to try it please leave a comment on that page and share how it went for you.


Don’t install the carrier update: Some iPhone 4 and 4s users are reporting real problems. Speeds slower than 3G. I’m not seeing it on my iPhone 5. Most of the time I have an LTE connection.

So yesterday I reported that I updated my iPhone 5 to carrier update TFW 15.7 and my phone was working fine. Today I am seeing a 3G network speed indicator in my status bar, when I used to see 4G. Readers are commenting that they are seeing this too.

I have an iPhone 5 and I have been getting LTE since October when I upgraded my Net10 & Straight Talk SIM cards. With TFW 15.6 my iPhone would indicate 4G when I made a phone call, went to voice mail, or a was sending / receiving an MMS. Otherwise most of the time, it shows LTE.

Now, my iPhone shows 3G where it used to be 4G in the cases I just mentioned.  If you have an iPhone 4 or 4S, your 4G is gone and you only have 3G. Don’t Panic.

Photo Dec 05, 4 35 02 PM What matters is the actual speed of your data connection, not the indicator on top.  The iPhone 4s supports HSPA+. This technology is technically just fast enough to label as 4G. Back in 2012, if you had an ATT iPhone 4s, your network speed indicator magically changed from 3G to 4G.  After 4G LTE became available for AT&T and Verizon, Apple didn’t have an LTE iPhone. Samsung and others did. This was a marketing problem for AT&T and Apple. The iPhone was their best selling smartphone and it didn’t use their fastest network available. The solution was to label HPSA+ as 4G. If I remember correctly, it was an AT&T carrier update that made this change

Not convinced? See Chris Zielger’s article over on The Verge,  iOS 5.1 shows ‘4G’ indicator in iPhone 4S status bar for AT&T

If you have ever used another type of smartphone, you’ll sometimes see a network indicator of H or 3.5G when the phone has a HSPA+ connection. I wish they would have just used H.

So ask yourself, did my iPhone really get slower?Install Speedtest.net Mobile Speed Test from the App Store and Run a test to see. Before I updated to LTE, I was getting between 2 to 4 Mbps up and 0.8 to 1.08 Mbps up.
What speeds are you getting? Leave a comment with your test results.

    Hi Bob, I met a similar problem with my iphone5. I lost my LTE signal with straight talk. I used their att sim card and only 3G showed up with slow speed. I tested with friends sim card (ATT contract) and at least 4G does show up. Any suggestions on how to bring LTE back? Thanks! PS, I’m using TFW 17.0 and iOS 8.0.2 now

    • Bob Thompson says:

      Hi Kay,
      What is the model number on the back of your iPhone 5? Did you lose LTE when you switched to Straight Talk, or did you have LTE with Straight Talk and it suddenly went away?

      • Kay says:

        Dear Bob,
        It’s A1429. I had LTE signal using StraightTalk last year and earlier this year. But since later April (or maybe even earlier) I noticed I lost LTE. Spent many hours over the phone talking with their associates since then but nothing helped so far.

        • Bob Thompson says:

          Hi Kay,
          Did your phone display 4G in the status bar or LTE in the past? Your A129 iPhone is the Verizon model which isn’t compatible with Straight Talk’s ATT LTE network. Not sure how you could have been getting 4G LTE with Straight Talk in the past. ATT’s network uses LTE bands(radio frequencies) 4 & 7. Your phone supports band 1,3 and 5. Were you a Verizon customer in the past? Where did you get this phone.


          • Kay says:

            Hi Bob,
            I used to get LTE in past with straight talk. I brought the unlocked phone from Asian to the states. Just to clarify that the model is A1429 (not sure whether it’s just a typo in your message). Hope this could give more hints. One more thing is that I did test with ATT sim card (from a friend who has an ATT phone) and it showed 4G although not as perfect as LTE.

  2. Ed says:

    Hey guys, I just bought a straight talk I phone 5 which was listed online on their website as 4g lte. But my phone is stuck on 3g, I called the company and they said sorry the phone will only ever run on 3g network. And I said “so you sold me a phone listed as 4g compatible and it’s not ever going to be 4g” and they “pretty much said yes, sorry”… I’m furious needless to say. There’s gotta be a way to fix this problem. Help if possible???

    • Bob Thompson says:

      Hi Ed,
      Your best bet is to return the phone, or exchange it for a 5c or a 5s. The Straight Talk iPhone 5 uses the Verizon network. Verizon only let’s straight talk use their 3G network. The ST iPhone 5s and 5c use the ATT network and supports 4G LTE.

      If you want to get 4G lte, you might be able to transfer your service to Verizon prepaid. They just started offering their prepaid customers 4G lte service.

      Ironically, if the att network works well in your area, you might find that by transferring your service to one of straight talk’s att SIM card will result in faster data. It will work with your phone. You’ll get 4g data, but not lte. The status bar will still show a 3G, even though it’s a 4g connection.

      May I asked what you paid for this phone? See if you can return it. I can probably make some recommendations for you or help you with other options.


  3. Brian T says:


    I read your other article and understood it well. It appears I’m hosed if I did not make a backup of her phone. Lying bastards at TFW and throttling our speeds to force us into new devices and ATT use of LTE. I live in Texas and I know ATT well enough to tell you they “Are what they are” and “A monopoly that we broke up in 1984″ to prevent this kind of nonsense. They slowly started rebranding again in Texas in their home markets and then abroad. Then today, we hear they are going to be permitted to buy DirecTV and their satellites? Is the FCC even awake or the USDOJ? Who is being bribed into this?

    Enough said about the rant, you all get the point. If you are on an iPhone 4S –

    If you have iOS versions 5.x or 6.x blah, blah and need iOS versions 7.0 to get blah, blah app for blah, blah, blah – DO NOT GET THE LATEST 7.1 or you will be stuck for sure! Make sure you stay on iOS 6! If you go to iOS 7 (do it offline with the first releases of iOS 7.0 and MAKE SURE TO MAKE FULL BACKUPS FIRST AND DO AT YOUR OWN RISK! You may lose all your data and IF YOU SUCCEED, at WORST you will get TFW instead of HOME at the top and 3G always instead of 4G as we can’t get the carrier update, even if I can revert back to iOS 7.0.x

    Bob, thank you for your help. I’m sorry for the rant but I think Apple and AT&T (who clearly collaborate well together) have done this and they practically own TracFone Wireless at this point anyway. I think I will figure out a way to revert my backup and tell TFW to “Go take a long walk off a short cliff” otherwise, I will go elsewhere. I believe LTE is going to be forced on us all. LTE sure is great, but is it really necessary? We lived fine with HSPA and had no care in the world about any network speed increases. We just wanted the latest iOS to stop getting BS about these app upgrades always being forced on us. Then BOOM! Your hosed, so I answer my own question and thank you Bob! If you think you have identified a link to downgrade the carrier for us few (me but not my wife) please let me know by email please. I appreciate these forums and the feedback from the few who actually left it…


  4. Brian T says:

    Hello Bob! If you are still monitoring this thread – thank you for this article. It is very helpful. Does this article still work about downgrading carriers for iPhone 4S? I just updated my wife’s iPhone 4S from iOS 6 something to the latest 7 via the device. It’s fully unlocked so we thought, “Who cares?” (Yes I know jailbroken can be better but we do not care on this device)

    As soon as we upgraded just a day or two ago to the latest iOS 7 something (I had to get her a new SIM card about two months ago) BOOM! Her data was suddenly throttled and much lower. We have always used the OOKLA Speedtest.net app and site but this is weird? Your thoughts are appreciated – I would like to downgrade her and see if this will fix her data speeds; she has certainly not reached her throttled limit of 2-3GB for sure (she may use 1-1.5GB if that). What gives Bob, your thoughts sir? Will this carrier update and downgrade listed earlier still work for us? I have an older version of iTunes on my MacBook Pro as I kept it around for this type of nonsense explicitly. Thank you Bob!

    • Bob Thompson says:

      Hi Brian,
      I was just headed out. So a short reply. With iOS 7.1, you can’t use iTunes to carrier the carrier bundle any more. I did have a reader, who jailboke his iPhone, and then was able to revert to the TFW 15.6 carrier bundle.

      I don’t know if you are willing to jailbreak your phone. Take a look through the comments if you want to read what that reader did. I’ll comment more later.

  5. chris anderson says:

    i downgraded once and it took and i accidentally upgraded days ago but i tried to downgrade again but it want pic up the ATT_TFW ..SO WHAT SHOULD I DO TO MAKE MY PC PICK THE DOWNGRADED TFW

    • Bob Thompson says:

      Hi chris,
      If you updated to ios 7.1, this no longer works. If you updated your iTunes, it may no longer work as well. Try repeating the steps by entering the commands in the command prompt again.

  6. david bright says:

    hi bob i have an i phone 5c and switched my verizon carrier to straight talk but i only have 3g is this all straight talk carries?


    • Bob Thompson says:

      Hi David,
      You will never see a 4G displayed on an iPhone using Straight talk anymore. It will show 3G ever even when you have a 4G connection. (HPSA+).

      Verizon iPhone 5 only supports 4G LTE on the Verizon network. The phone is compatible with LTE on any other network.
      If you are using this 5C on Straight Talk’s tmobile network, my guess is you will only get 3G. If you are using their att network you might get LTE, At least one reader told me he was. Are you using the Straight Talk ATT SIM?

  7. Oscar Aguilera says:

    So I never can I get 4G..??

  8. David vail says:

    I have an iPhone 5 on straight talk and I can’t get any better connection then “E” but when I leave my county I get “3G” but still cannot use the internet. What do I do? Ps I can send texts and make calls perfectly fine

    • Bob Thompson says:

      Hi David,
      Are you using Straight Talk’s AT&T network-compatible SIM or Straight’s Talk T-Mobile network-compatible SIM? What color was the plastic card your SIM was attached to?

  9. dylan says:

    Hey Bob,
    I thought Id offer an update. My iMessages on my iPhone 4S has been not working. I also updated to 7.1 iOS which I like. I did a reset after I did this uninstall to 15.6 to maintain 4g speeds. Subsequently, I just did a test via speedtest.net upload 6 mbps DL 1.08 mbps UL and the carrier data v. TFW 16.0

    I found this interesting because this is faster then the old 4G rate but now my phone says 3G.

    Just wanted to share.
    I might download the old TFW carrier software see how that tests. Thanks, appreciate your work and site

  10. Cory says:

    Hey there, I’m curious if you have heard anything on the 15.8 tfw update. I’m unable to downgrade back to 15.6 because unfortunately my laptop crapped out on me and completely crashed. So no iTunes trick, if possible is there a way to do it without a PC? Thanks I eagerly await an email -Cory

    • Cory says:

      Also my ping is around 175 down is around 0.01-0.03 and up is 0.02-0.05 mbps -Cory

    • Bob Thompson says:

      Hi Cory,
      I have not found a way to do it without a PC or Mac. Use a friends PC, or hit up the Apple store and use a Mac on the floor. I haven’t heard anything about a TFW 15.8 or any acknowledgment of a problem with TFW 15.7 so I don’t know when its coming or if it will fix any problems.

  11. Jerry Mendoza says:

    Hi there I’m running an iphone 4 att locked ios 7.0.4 ever since I updated the carrier network my speeds test average 0.04 mbs down and 0.03 mbs up

    Horrible speeds I’m beginning to get frustrated I downgraded the 15.7 to 15.6 and still same speeds I’m on the unlimited data and text and talk plan

    Help pls

    • Bob Thompson says:

      Hi Jerry,
      Did you Tap Settings->General->Reset and Tap Reset All Settings? This will erase your network settings, but not your contacts, calendar, photos, etc. Sometimes this helps.

  12. Tyler says:

    Hi my name is Tyler and I have a Iphone 5 that i use with Net10 and My 4g has now changed to 3g and i would like to know why because my speeds have changed please and thank you.

  13. Doug Joseph says:

    I’m new to Net10. I just bought an iPhone 5C from Net10 about a month ago, and I don’t know for sure if I’m connected to Sprint towers (CDMA) or AT&T towers (GSM), but I think I might be on Sprint towers. How can I tell?

    My phone’s About page says my carrier is TFW 15.5

    My speed test ratings show downloads of 2.17 and uploads of 0.84, with a ping speed of 142.

    Should I try to update to TFW 15.6 or 15.7?

    Thanks for any help you can give. Much appreciated!

    PS: love this site.

    • Bob Thompson says:

      Hi Doug,
      I think it should be an AT&T phone. What’s the model number on the back of the phone? Did you put a SIM card in this phone when you activated it? I am a little confused by the carrier being TFW 15.5 though.

      For now, try this. Go into setting general reset and tap reset network settings. (you’ll need to reenter your wi-fi passwords later)

      Run speed test again. Let me know.

      • Doug Joseph says:

        Thanks, Bob!

        This phone’s SIM tray is empty. It came that way from Net10.

        The model number on the back of the phone says: Model A1429

        (As best as I can tell. Those are tiny numbers!)

        I did the reset of network settings.

        Afterward, it searched and settled on “TFW 3G” and in “Settings > About > Carrier” it still says “TFW 15.5.”

        My speed test ratings were worse, but that could be due to other factors, such as net traffic, right? I now show downloads of 0.84 and uploads of 0.63, with a ping speed of 129.

        Previously, before the network settings reset, my speed test ratings showed downloads of 2.17 and uploads of 0.84, with a ping speed of 142.

        • Doug Joseph says:

          I rant the speed test, and its getting worse each time. Going down instead of up. I’m guessing the time of day, and net traffic, affect the results, right?

          This time my speed test ratings showed downloads of 0.42 and uploads of 0.64, with a ping speed of 126.

        • Bob Thompson says:

          Hi Doug,
          Sounds like you are using Net10’s Verizon-compatible network. Carrier TFW 15.6 and TFW 15.7 are for iPhones using the Net10 AT&T network compatible SIM card, not Net10’s Verizon compatible network. That’s why your phone is on TFW 15.5. 15.5 is the latest for your phone.

          If you installed the profile, it shouldn’t hurt your phone. I will just revert back to TFW 15.5. Your iPhone 5 is using Verizon’s 3G network. Verizon has no opened their 4G LTE network to prepaid companies like Net10 yet. I don’t know why your phone is slow. It could be the phone, that the Verizon network is busy, or something to do with Net10. Run more tests from different locations, at different times. Just for comparison, my speeds on Net10’s ATT network vary I clocked 29mbps down one day this week and .75 mbps down the next day.

          Try reseting the network settings and see if it get’s faster.

          It is also possible to move your phone from Net10’s Verizon network to their AT&T network. You won’t get 4G LTE speeds because your Verizon model iPhone 5 is only compatible with Verizon’s LTE network. You will get net10’s att 4G network, which may be faster than net10’s verizon 3G network. I don’t have hands on experience with the verizon 3G network. I suspect the ATT network would be faster but their are other factors including how well covered your area is by each network.

    My iPhone 4S showing 3G when I pay for my $60 plan

    • Bob Thompson says:

      Hi Luis,
      Run the speed test and try to figure if your phone is really slow. Try following the guide to revert your phone to carrier TFW 15.6

      • John baddley says:

        Hi bob, I just purchased a used iphone 5 and had it activated on net10. It showed home as the carrier and 4g. I restored the phone in iTunes from a back up, now it shows tfw and 3G. My download speeds are 6.2 Mbps and everything works. Should I leave it alone or downgrade software from 15.7 to 15.6. Thanks

        • Bob Thompson says:

          Hi John,
          It’s hard to say. Your download speed is pretty reasonable for a 3G/4G connection. So if you are a “it ain’t broke don’t fix it kind of guy” then leave it alone. Typically, people reporting 6mbps down say they don’t notice an improvement. Some readers swear, there phones drop to under 1mbps when the get TFW 15.7 and it gets goes back to normal when they revert.

          You can give it a try if you are comfortable with following the instructions. I never had anyone say it messed up their phone. Once you revert, your phone will sense that the TFW 15.7 update is available so its easy enough to go back.

          I am curious though if you are getting LTE. If your iPhone 5 is an AT&T / GSM model I’d think you would be getting LTE. If your using a Verizon iPhone 5 you’ll only get 3G/4G. The radios in the verizon iPhone 5 aren’t compatible with the Net10 ATT compatible network.

          Let me know if you try and how it goes.

  15. Victor Zambetti says:

    I did a test& the results are downloads is 1064.6 uploads are 135.5 & ping is 430.My phone says 3G before the apple update it was 4g.

    What’s the point of constantly putting “Regards, Bob” when your name is clearly on top of your post?

  17. Victor Zambetti says:

    Hi,I had 4g now 3G since the update to 15.6to 15.7.i did a speed test the results are (download)1064.6 (uploads)135.5)(ping)430

    Thank you

  18. Traci Moore says:

    I have an IPhone 4S and I updated the carrier settings, normally I would have had 4G now I have 3G and have had it for about a month. I’ve tried resetting my network settings and resetting the phone itself. Nothing has worked so far. My internet used to be a lot faster now it’s a whole lot slower.

  19. Tonio Gonzalez says:

    So tell me, I have an iPhone 5 from AT&T .. Joined net10 when carrier name was (home) was getting 4g label but then when I upgraded carrier it went to 3G ..? I mean I get LTE mostly my area.. But I want to know why from 4G to 3G?

    • Bob Thompson says:

      Hi Tornio,
      I thought I described it pretty well in the article. Was there some points in there that weren’t clear?

      • Adil says:

        I did upgrade to 15.7, now my iPhone 5 is acting strange, one moment will work the next wont recognize the SIM card, anyone having the same issue from net10?

      • Natalie says:

        Sure, you explained iPhone 4 and 4s pretty well regarding 3g vs 4g..but the meat of your article discussed how to fix this on THOSE phones, not the iphone 5. I have a 5, same exact issue ..used to be 4g, now 3g. No I haven’t downloaded the speed app, but I really don’t need to because I can tell. The speed is visably slower when connecting to anything using my data, than it was prior to this “G” change. Would you mind emailing your response or any tips? I’m afraid I’ll miss it on this thread as I typically am not good at going through thread after thread seeing if its been answered. Your help is awesome and appreciated!!!!!


        • Bob Thompson says:

          I clearly said in the article that I have an iphone 5. I mention the iphone 4 and 4s because that’s what readers have reported. The fix I describe is for all iphone running ios 7. It’s not just of the 4 or 4s.

  20. Chester Bergey says:

    I was wondering if there is any way to go back to ios6 cause I don’t really like the update. Looks about like android. Ios6 had a more classic look to it I think.

  21. Alexis says:

    I have a iPhone 4 & I updated my phone & now my internet is working really really slow

    • Bob Thompson says:

      Hi Alexis,
      This seems to be the case for many. My suggestion would be to run speedtest take some measurements and then try reverting to TFW 15.6
      Seems to help many.


  22. David says:

    I have reverted to 15.6 and reset settings per Bobs instructions. My speeds vary a lot even though I have the 4g back. I have seen downs up to 19 and ups to 6. I can’t complain… Still very happy with ST.

  24. jack w says:

    Wow – I’m glad to see I’m not the only one who noticed this change! Thanks for all your work Bob! Here’s my speed test results:

      • Bob Thompson says:

        Hi Jack,
        Hmm. I find my speeds vary quite a bit. My LTE is currently quite a bit faster that that. I found that some people were crushed by this update. Up / Down both below 1mbps.
        While not fast, are you definately noticing its slower? Did you restart your phone afterwards with a reset all settings?

    • Bob Thompson says:

      Hi Jack,
      Thanks for sharing the speed results. That actually looks like 3G speeds.

    i have tried everything it dont work halp plz…

  26. luis says:

    Hi Bob. i have an iphone 5 with the same problem, it used to show home 4g lte, now is tfw 3g, after i updated. and my data is slow… can’t even use pandora,

  27. Chester Bergey says:

    Do you think that will change with future updates?

  28. Trent says:

    I have a 4s and there were two updates recently. The first one I skipped because I was busy. The second one, I updated. I think it went to TFW then, and within a few hours went to 3G from 4G. However, I noticed no differences in speed.

  29. Payam says:

    Hey Bob, Looks like you’re in charge here.

    I have a 4s att with straight talk and it used to say 4g and now only says 3g.

    Im not sure if my data in any slower now that it is 3g as compared to when it was 4g. Is there a difference in speed? If so, how do I go back to 4g?

    I tried doing what you posted above but i can’t get it to work..

    Thanks in advance.

  30. Scott Mathis says:

    I just got the turn your phone off message again today. I did and it fixed the issue still shows 3G but the speeds are fixed. This must be 15.8.

    HI bob..i updated to 15.7 aswell i had 4g and now im down to 3g!! its definetly ALOT slower..i just got off the phone with straight talk..i spoke with a “manager” for over 30 minutes about this issue.she was of no help..i asked her if this was permanent she said that she didnt think so…any fixes yet? i have another question aswell…she looked up my sim card and told me i did have an LTE sim…i was convinced i didn’t..i thaught the LTE sims just came out recently..ive had this sim since january 2013 and i have never gotten LTE on my verizon iphone 5…only 4g…..any idea on how to get lte on the verizon iphone 5 if i apprantly already have the LTE sim once they fix this issue?thanks for your help!!

    • Bob Thompson says:

      Hi Chris,
      You won’t get LTE on your Verizon iPhone 5 because it only supports the Verizon LTE bands and not the ones used by the ATT network. So I don’t think updating your SIM is going to help. The new Verizon iPhone 5s supports the LTE bands used by AT&T, but I have not had a confirmed report of getting LTE using Straight Talk. If you know a friend with an iPhone 5 on ATT getting LTE, ask to try their SIM in your phone and you can see. I’d turn off iMessage first though.

      I am working on a tutorial to show people how to downgrade to carrier TFW 15.6. I hope to publish it VERY soon. Keep an eye on this post for updates.


  32. Melissa says:

    I have an iPhone 4S from AT&T and I switched to straight talk, it was wonderful until I recently updated it. I now have 3G and it’s so slow.

  33. Clint says:

    Hi Bob. Thanks for all of your info on this issue. My wife and I both have iPhone 4S and got the TFW carrier update and are both having the speed issues. I spent over an hour on the phone with the straight talk tech trying to figure it out with no success. How do I downgrade this carrier update as you have? Thanks!

  34. Chaselea says:

    I updated my carrier settings on my iphone 5. Since then my 4g is gone and my internet is extremely slow! How do you fix this?

  35. danny says:

    I have iPhone 5 on ATT LTE
    Speedtest: Download 11.51 and Upload 4.63
    About to pull the plug on ATT and move to Straight talk

  36. Deb Pysno says:

    Hey Bob,
    Thanks for advising NOT to do the ST carrier update. I did notice they offered a new one today. Does it fix the slowdown? — not that I’m going to do it until YOU tell me to. ;-)
    Your readers want to know.

    • Bob Thompson says:

      Hi Deb,
      I heard a rumor today that there will be an update in one day. I don’t know if it is reliable or not. If you are on TFW 15.6, you phone will occasionally prompt you to download the latest update. There is no way for you to know if that is 15.7 or 15.8.

      I actually downgraded to TFW 15.6, and my phone immediately started prompting my to update back to TFW 15.7(supposedly).
      Keep an eye on smartphonematters.com. Oh, and props to you for checking before updating. :-)


      • Jerome says:

        How can u downgrade the carrier to 15.6? i’ve look all over for the file.. i’ve installed custom carrier files threw itunes .ipcc files in the past.. i cant find this file anywhere

  37. Technut says:

    The iPhone I have also displays the same however now I am unable to access the data network..

  38. Scott Mathis says:

    Bob I did the update as well, and I cannot even use YouTube on my now 3G. Can you help? Thanks!

  41. zach says:

    well I just went ahead and updated it to TFW 3G I don’t see a difference the internet and all is still fast just see 3g makes it look cheap but really its not but I read a forum saying within 24hrs there should be another update to get back to 4G? if its true

  42. Jermink says:

    Down: 0.41
    Up: 0.04

    This is my speed after that stupid update. My phone use to move way faster!

  43. KS says:

    UPDATE: WIth 4 Bars on “3g” with Iphone 4s
    Down: 5.12 MBPS
    Up: 1.13MBPS

  44. KS says:

    Same happened to me in Atlanta(3g indicator after updating carrier settings).My speedtest.net speeds are
    ping: 121ms
    Down: 8.08 MBPS
    Up:1.12 MBPS
    With 5 full bars.

    Will test it at home(where I have less bars and post it later)

  45. zach says:

    I updated my Straight Talk iPhone 5c and had TFW 4g now I see TFW 3G but when I erase my iphone and icloud everything back on the phone I see HOME 4G which should I stick with

    • Bob Thompson says:

      Hi Zack,
      If you feel like you phone got slower when you saw the 3G, then leave your phone the way it is now. You’ll need to install an APN or sim swap to get data or data and mms respectively. If you check you carrier, you are probably back at ATT 15.5.

      If you think you have a problem with you phone let me know.

  46. Makay says:

    I updated my phone to 15.7 and my data speeds are definitely slower than before. I tried restoring previous back-ups of my phone but still have the 15.7 update. I really wish I could figure out a way to get back to the old carrier update.

  47. Makay says:

    I also updated to 15.7. I tried resetting all of my settings and even restoring previous back ups of my iphone yet I still have 15.7. Data is much slower with the new carrier updates besides saying it is 3g vs 4g.

  48. Lisa says:

    Whats the problem with TFW update 15.7 ?
    I lost 4G now my phone only shows 3G…

  49. Chad Barr says:

    I wish I had seen this before I updated. I now have the 3G icon and my speedtest results are:

    3 bars
    Ping: 266 ms
    Download: 1.18 Mbps
    Upload: 0.12 Mbps

    Bob please help!!!

  50. Jesus Martinez says:

    I used to get download speeds of 3.50 lowest ive ever been was 3.33 since ive been with net 10 but… with the new carrier update ive have 2.98 and 3.00 speeds its not much to tell a difference but still i liked seeing 4g up there

  51. Will says:

    I use straight talks latest lte/4g SIM card on my iPhone 5c.It always indicated 4g when lte was not available. Since I updated the recent carrier settings 2 days ago now it reads 3G when lte is not available. I didnt notice any speed changes/drops since the update, I could be wrong though.

  52. Christa says:

    I have an iphone 4s running ios 7.0.4 and updated to the TFW 15.7. It has slowed down my data so much that it takes sometimes over 2 minutes just for a page to load enough to read it. It wasn’t like this a couple weeks ago, before I updated. I mean it was never super fast, but the page loaded within 20 seconds. Ive tried resetting all data setting and then resetting the phone a few times but no change. Also my 4g went to 3g, which I guess is just a mental thing, but I liked the 4g up there, lol. My speed test, with wifi off, shows:

    4 bars
    Ping-749 (this jumps from around 200-2,000 with each test)
    upload- 0.04

    This sucks because I mostly use data,since my home wifi is so spotty and maxed out with computers, game systems and ipods. Hopefully they fix this soon. Like I said before, my data speed was pretty good before the update. ALso, I can now send MMS but not receive. Before I couldn’t even send, but with all the messaging apps out there that wasn’t a big deal. Kinds strange that mms can only go one way though.

  53. Steve Mills says:

    This morning I get a text message from straight talk telling me to power off and power on to receive the latest update. I dutifully did so. I see no changes.

    I still have it showing 3G and the speed seems okay. I haven’t noticed, in my case, any particular degradation since the 15.7 update.

    Interestingly, I got the text message from straight talk, but my wife didn’t. She has a 5 and I have a 4S. Obviously, I don’t know if that mattered. I haven’t updated her phone to 15.7 Yep, and don’t intend to Ontell some of these issues have a resolution.

    • Bob Thompson says:

      Hi Steve,
      Yes. Avoid TFW 15.7. Those power down messages see to be sent out in batches. No everyone gets it at the same time.
      Nice to see you commenting again.

  54. Bayardo Estrada says:

    How can I get it back to 4g instead of 3G ????? Help

  55. Kush says:

    I really would appreciate some help! I have an iphone 5 with the lte SIM card with straighttalk. I never got lte because I didn’t have the correct profile but after this update my download is at 4.02 and upload is at .50. This is extremely slow and I can’t not do much with this slow speeds! I would really appreciate some help. Thanks

    • Bob Thompson says:

      Hi Kush,
      Your issue with LTE may be your SIM card. I needed to update my old card to a new one that was advertised with LTE support. It’s unfortunate that TFW 15.7 is causing you issues. I am working to find a fix.
      Keep your eye on smartphonematters.com for updates.

      • Kush says:

        I have the new lte SIM card. I had to cut it down to a nano sim to use it. My speeds are around 6.3 download and .97 upload. I usually got those before but I’m not getting lte speeds which I should be getting.

  56. David says:

    I too have installed the 15.7 update. Same deal, now I get 3G sometimes and not LTE or 4G. I have noticed that my speeds are much slower with the update. Straight Talk needs to fix this issue quickly. What do you think Bob?

    • Bob Thompson says:

      Hi David,
      It is unfortunate. I really don’t know what is going on with ST. I installed TFW 15.7 myself, and didn’t see a performance problem. Just the 3G icon. Many people are. Keep checking smartphonematters for updates. Thanks for sharing your results. I am just one guy using Net10 and ST. The reader comments really help everyone get a sense of how bad the problem is.

  57. Tom says:

    I did the update and lost my 4g internet speed is horrible any can help thanks

  58. Craig says:

    I got the message to update carrier settings and I did. My 4G changes to 3G as well. Have not seen any change in speed to speak of.

  59. Nathan says:

    Same downgrade in labeling happened to me when agreeing to carrier settings update prompt. I am using an unlocked iPhone 5. I never see 4G labeling anymore but here is a speed test I just completed when on LTE and 3G.

    Download: 19.44 Mbps
    Upload: 4.62 Mbps
    Ping: 173 ms

    Download: 2.77 Mbps
    Upload: 0.97 Mbps
    Ping: 190 ms

  60. Jose R Perez says:

    Hey guys before I did the new carrier update on my Iphone 5 I was getting speeds between 10 – 15 Mbps with 3 signal bars and now my internes is really slow I’m getting speeds between 0.1 – 0.17 Mbps with 3 signal bars any help?

  61. Arturo says:

    The speeds are pretty good but it’s a mental thing. At least if it was an H it won’t look like cheap 3G. I am not impressed with this update

    • Bob Thompson says:

      Hey Arturo,
      I agree that using and H and 3G would be better. It would be accurate. At least your phone seems to be working ok. A few people have some seroius issues.


  62. Chris Lupu says:

    Just “Upgraded” to 15.7 Have lost 4G my speed test app used to show 24.97 up and 5.35 down 22ms ping now it’s down to 6.5 down .73 up 340ms ping…Called customer service they said they have been getting calls nonstop today since the “upgrade” was sent out, they offered absolutely no help whatsoever…my monthly cycle is set to expire in 2 days…I would like to know if they are intentionally dorpping 4g service on AT&T towers..If so, I need to find a new carrier…and quick…

    • Bob Thompson says:

      Hi Chris,
      I never got such impressive speeds when I was on 4G. I assume you reversed the up / down combo there. I rarely get those speeds using LTE. Your 3G speeds are more like what I always got when my iPhone was 4G. Admittedly, I’d only have two or three bars at home. I don’t know why it would make any sense to drop 4G service on AT&T after bringing back the ATT SIM and 4G LTE this year.

      I was looking at AIO and ATT Pay N Go to review for the site. AIO claims 4G LTE up to 8 Mbps. I don’t know about Pay N Go. Keep checking the site for more info.

  63. Jamie says:

    Up is 0.00
    Down is 0.74

    I can tell that my phone is considerably slower than it was earlier today before I updated carrier settings.

    • Bob Thompson says:

      Hey Jamie,
      Do a reset on your phone and test again. Hold Home and Lock till the phone reboots. That isn’t 3G speed, that isn’t even 2G speed.
      Let me know how it goes.

      • Jamie says:

        Did the reset.
        Down .08
        Up .21

        I tried it again as well just to be safe and I got worse results.
        Down .05
        Up 0.00

        • Bob Thompson says:

          Hey Jamie,
          That is messed up. But this isn’t 3G, you are seeing a 3G indicator.
          Do you have an APN profile installed. Remove them if you do. Settings-General-Profile
          I’d try a Settings->General->Reset->Reset All Settings
          Then retest you data.
          You are seeing a 3G in the indicator? How many bars?


          • Jamie says:

            I currently don’t have any profiles on my phone. I figured out after the last one updated carrier settings in October that we didn’t need them anymore.

            I have anywhere from 3-4 bars at all times and a 3G indicator as well.

            Earlier today I have full service with 4G before updating.

            **Just tried the reset again. And even did what you suggested and Reset all the settings.

            Down: 1.32
            Up: 0.50

            Earlier today I had full service with 4G before updating.

            I tried the hard reset again and also reset all my settings.

            Down: 1.32
            Up: 0.50

          • Bob Thompson says:

            That is bad. I guess this is going to be a crisis for many. Can you try restoring from a recent backup?

  64. Steve Mills says:

    Like everyone else I am showing 3G after the most recent update. I have a 4s with the most recent Smarttalk sim. The phone doesn’t “seem” slow, but I honestly don’t know what my prior readings were.

    Right now Speedtest shows roughly one up and six down, although this varies considerably during peak hours.

    • Bob Thompson says:

      Hi Steve,
      Your speeds are more or less in line with what I was getting before LTE. I’m thinking they changed the indicator. Thank you for sharing your results. Let me know if you notice a difference moving forward.
