A reader, Crystal, asks…
I have a straight talk iPhones 5 16gb. I have a friend that gave me his iPhone 6 64gb that was on sprint. I have checked online and it says this phone will not be compatible with straight talk, but I tried swapping my SIM card anyway. It works in the new phone. In your article it says this can cause problems later on. If I buy a activation kit and put the sprint sim in will it work? If I deactivated my iPhone 5 to give to my step dad is this going to cause problems with my new phone? I really want to use this iPhone 6. In your opinion what is my best option
The Sprint iPhone 6 your friend gave you is a model A1586 which is compatible with the Sprint network. If that iPhone is unlocked it should also be compatible wit the AT&T, Verizon, and T-Mobile networks too. Since you were able to move the SIM from your iPhone 5 into the phone and it worked the phone is probabally unlocked.
Your Straight Talk iPhone 5 is mostly likely using Straight Talk’s AT&T or Verizon network. If it’s using the Straight Talk AT&T network. You can move the SIM card to the iPhone 6 and it will be fine. If however your iPhone 5 is using the Straight Talk Verizon network, you don’t want to move the SIM. With Straight Talk’s Verizon network, your iPhone 5’s serial number is registered on the network and your account is associated with that phone and SIM. If you try to activate that iPhone 5 on Straight Talk’s Verizon network again you will have need to transferred your service to a new phone or SIM. See my video response below.
