Using a Sprint iPhone 5s, iPhone 5c, or iPhone 5 with Straight Talk Wireless

Many readers ask me about using the Sprint iPhone 5s, iPhone 5c, or iPhone 5 and in this article I’ll with you what I know about it. I personally do not use a Sprint iPhone nor use Straight Talk’s Sprint network so I do not have first hand experience with the matter.

Straight Talk uses 4 different networks (ATT, Verizon, Sprint and TMobile). When you sign up for Straight Talk your phone will use one of these four networks. Usually Bring Your Own Phone (BYOP) customers use the same network they were on or that the phone was sold for when moving to Straight Talk.

So for example, if you were a Sprint customer, or have a Sprint iPhone, you’ll use it with Straight Talk’s Sprint network.

Using the Straight Talk’s Sprint Network

To use your iPhone with Straight Talk’s Sprint network, the phone needs to be eligible. The phone has a ID number called an MEID. You’ll need to check the MEID with Straight Talk to see if that specific phone is eligible. You can find the MEID in the phone’s settings.

Not all phone’s are eligible. If the phone was reported lost or stolen or the phone is still under contract, you may not be able to use it. Worse, if you do register the phone it’s possible in the phone’s ESN could be marked as bad and the phone will no longer operate on the Sprint network.

If your Sprint iPhone 5s, 5c, or 5 is elegible you then need to purchase a Network Access Code to register it on Straight Talk’s Sprint network.

It’s not clear to me if you’ll be able to get 4G fast LTE service or be limited to slower 3G service. Usually Sprint phone would need a SIM card to get 4G LTE service and Straight Talk doesn’t currently sell them.

Using the Straight Talk’s Verizon Network

Your Sprint iPhone 5s, 5c, or 5 might also work with Straight Talk’s Verizon network. Use the same steps above to see if the phone is eligible for use on Straight Talk’s Verizon network. Like with the Sprint network you’ll need a to buy a Network Access Code. If you are able to use your phone with the Verizon network, you should also buy a Straight Talk Verizon nano SIM so you’ll get 4G LTE service. Several smartphonematters readers have told me they have done this. The details are not clear.

Using the Straight Talk AT&T or TMobile Verizon Network

If your iPhone 5s, 5c, or 5 is unlocked it will work with Straight Talk’s ATT or TMobile network. You just need to get the right SIM card. I recommend you make sure the phone really is unlocked before buying though. You can to this by finding a friend that uses an iPhone 5 or later with ATT or TMobile. Borrow their SIM and put it in the phone. If the phone is unlocked, you’ll be able to make phone calls from that persons phone number. Sprint iPhones sold after a certain date are unlocked. Previously sold phones are locked but you may be able to get Sprint to unlock the phone for you. Unlocking Your AT&T, T-Mobile, Verizon or Sprint iPhone, Android, or Windows Phone

    Straight Talk supports both Sprint and Verizon LTE devices and they require SIM cards. In order to activate the some Sprint LTE devices (LG G3) you need to get the MSL from Sprint in order for Straight Talk to be able to put it on their Network. The Galaxy S6 is capable of being SIM/GSM unlocked. The iPhone 5c and 5s are also capable but they have to meet certain requirements. The contract obligation has to be met before Sprint will unlock a device; no different than AT&T. Sprint will domestically and internationally unlock these devices. I am 100% positive as I have done this and sold the phones as unlocked GSM phones. This then makes the phone usable with ATT or T-Mobile or any GSM carrier in the USA with a domestic unlock and any GSM carrier worldwide if the International unlock is done as well. The Sprint iPhone 5 is not capable of a GSM domestic unlock it would have to be done using the MSL. I am 100 % positive in regards to this information as I do this on a daily basis since I am in the industry.

    As for Verizon devices…
    Since Feb of 2015 all Verizon 4G LTE device are capable of running on Straight Talks network w SIM cards as Verizon phones. Additionally all Verizon devices are GSM unlocked. With some minor configuration they can be run on AT&T or T-Mobile’s or any GSM carriers network worldwide. The issue is since they use different LTE bands they‘re more than likely only going to get HSPA+ speeds for data (4G before LTE was available which actually come to 42.2 mbps). If you have used an unlocked Android before you have probably seen this. Even factory unlocked GSM devices do no cover (are compatible) with all LTE bands

    I hope this clears the air…

      Hi Ian,
      Thanks for the comment.

      I wasn’t aware of the differences unlocking Sprint phones, especially the iPhone 5 vs iPhone 5s /5c. I read that some customers trying to get their Sprint iPhones 5 (plural of iPhone 5) unlocked. were given MSLs, and of course that there was no way to enter them into the phone.

      I have written a number of articles about using Verizon iPhones with Straight Talk both with ATT and TMobile network SIMS and the Verizon network.

      I am not that familiar with Sprint offerings though. Several readers have told me they are getting LTE on Straight Talk’s Sprint network without the use of a SIM card. As far as I know Straight Talk sells SIMs for their Verizon LTE network, but not Sprint. A few readers have told me they have activated Sprint LTE phones on Straight Talk’s Verizon network, or at least it sounds like that.
