Switching a Verizon Samsung Galaxy S4 to Straight Talk Wireless

gal_pi01

A reader, Julie, asks..

Hello. We need to switch our phones from Verizon to a prepaid plan. I currently have a Verizon Samsung Galaxy s4 that I would like to switch to Straight Talk. I have read that I can do this with an ATT sim card. My question is once I do this, will it only work on the ATT network? Where we live there is only Verizon service, so I need to find a way to use a smartphone with Verizon’s networks. I would appreciate any thoughts you have as to how to do this.
Thank you!

Hi Julie,

Straight Talk Wireless uses the AT&T, T-Mobile, Verizon, and Sprint networks.  You want to check with Verizon to see if you can register your phone with Straight Talk using the Verizon network.   Just go to the Straight Talk Wireless web site.

You’ll enter your phone’s serial number and your location and check if it is possible to transfer your phone to Straight Talk.  I have never used a Verizon phone on Straight Talk.  They also use the Sprint network.  You might want to confirm with Straight Talk support that they won’t register your phone on the Sprint network.  I looked it up, your phone should be a SCH-I545 model, which I doesn’t look like its compatible with Sprint. You can call them and ask.

I’ll also mention that as far as I know the Straight Talk’s Verizon network is 3G only, not 4G LTE. Supposedly, Verizon doesn’t allow any of the prepaid cellular services to use their LTE network. If you get 4G LTE service where you live on Verizon, you may notice a difference in data speeds.  If your S4 is still active on Verizon, install the SpeedTest app, and see what types of data speeds you are getting on Verizon.

You don’t need a SIM card to use your phone on Straight Talk. In the US, we use two different cellular technologies: CDMA and GSM. Verizon and Sprint use CDMA.  AT&T and T-Mobile use GSM.  Since there is not AT&T service where you live it doesn’t matter but If you want to use a Verizon phone on the AT&T or T-Mobile network your phone model needs to be compatible with the network you want to use it on and the phone needs to be SIM unlocked.

You might want to take a look at Verizon prepaid  as well.

I hope this helps. Let me know if you have any more questions or need more help.  I’d also love to hear how it works out for you.

Regards
Bob

    i have a verizon galaxy s4 model sch 1545. If i unlock the phone from what i can gather here i can use it on at&t network. I live in an area where all major carriers are supported. When I tried the check your phone it said that it was unsupported. I dont care if I only get 3g speeds I just dont want to loose my phone altogether.

      Hi Chris,
      You Samsung Galaxy S4 may already be SIM unlocked. Find a friend with an AT&T or TMobile SIM and try putting their SIM in your phone and seeing if it works. Verizon is legally regarded to keep some of their LTE phones unlocked. (for example, all their iPhone 5 models are). when you go the the Straight Talk website and enter your phones IMEI it says it is unsupported because the phone can’t be registered on Straight Talk’s Verizon or Sprint compatible networks.

      In your case, you’ll be transferring your service to a Straight Talk SIM, and then using the SIM in the phone.

      Let me know if you have more questions.
      Regards

    I’m trying to switch my Samsung Galaxy S4 that i singed w/ Verizon a 2yr. contract smartphone to straight talk network. I read the article above went to the website and entered the IMEI# & zip code & the page just keeps refreshing. Does this mean something? The phone was new so do I need to get the sim unlocked? If so how?

      Hi Jonathan,
      Straight Talk buys airtime from ATT, TMobile, Verizon, and Sprint. My understanding is that Straight Talk will not register your Verizon s4 on ST’s verizon network due to a contractual agreement with Verizon, which states no Bring Your Own Phone for Verizon phones. The SIM slot on your phone should be unlocked, which means you could use Straight talk’s ATT or TMobile network. What is the model number of your phone? We would have to check the specs to see if it will work on those networks and whether or not you’ll get 4G LTE or not.

      If you have a friend with an ATT or TMobile SIM, see if you can try it in your phone to see if it works.
      Regards
      Bob

    Can you let me know if its possible to switch my families verizon smart phones and hotspot to straight talk. I have galaxy s4 sch- 1545 my mom has tge note II and my dad has the casio

      Hi April,
      Yes. You can activate your Verizon CDMA phones on Straight Talk. With the two Samsung phones you’ll need to decide if you want to activate them as CDMA phones on Straight Talk’s Verizon network or try to use them with Straight Talk’s AT&T or T-Mobile network.

      If you use the Straight Talk Verizon network, you will get 3G data speeds not 4G LTE. Verizon doesn’t let Straight Talk use their 4G LTE network. if you use their AT&T network you may get 4G LTE data. We will need to check the specs on your phones to see if they are compatible with the ATT LTE network. This might be possible with the S4 and the Note II. I didn’t look at the casio,

      Straight Talk recently started selling their own hotspot. I am not sure if you can bring your own hotspot to Straight Talk.

      You may also want to look at Net10 to see if you can get a better family plan. (Straight Talk and Net10 are owned by the same company. But offer some different pricing plans.)

      Do you know if the AT&T network coverage is any good where you live? We can work up a migration plan to help you out.
      Let me know.
      Regards
      Bob
