Can a unlocked verizon iPhone 4S work on straight talk?

My buddy has a verizon iPhone 4S unlocked and I want to buy it and put it on straight talk because I believe the iPhone 4S is both gsm and CDMA

Unfortunatley no not just simply getting a unlocked iphone 4S. You would need to flash it through a system that normally only stores have access to! If it takes a simcard then yes you can! Just make sure that it takes a simcard.

The Straight Talk website says that they will not allow a Verizon phone to be used for their bring your own phone service. You will need to call Straight Talk and ask them if you can use a Verizon Iphone 4 on Straight Talk or not. But according to their website, you can't.

  • Will my Verizon iPhone 5 work with Straight talk? My verizon bill is way too expensive and I need to cut down on bills. So I was wondering if I can switch my Verizon iPhone to straight talk and if it would still run on the verizon towers like some of the straight talk phones do?
  • Will a verizon iPhone 4s work on Straight talk? I have an iPhone 4s which is locked on verizon, there are ways to unlock it, but my question is, will it work on Straight Talk if unlocked? I read somewhere that if unlocked it will work on any gsm network?
  • Will a Verizon iPhone 4 Work on Straight Talk? I have a Verizon iPhone 4. Will it work on Straight Talk's $45 Unlimited Everything plan? I'm open to jailbreaks and unlocks.
  • What SIM card should I use to put my unlocked Verizon Iphone 5c on straight talk? I just purchased a GSM unlocked Verizon Iphone 5c and am currently trying to put it on straight talk. I've purchased the BYOP kit from walmart and I know I need to use the nano sim but IIm not sure if I should use the at&t compatible SIM card or the T mobile? Or does it not matter? Any feedback would be really appreciated.
