Will a Verizon iPhone 4s work with my AT&T plan?

My less-than-a-month old iPhone 4s took a swim and is unusable. A friend is upgrading to the iPhone 5 on the Verizon network. She has offered to give me her phone. Will it work with AT&T's network? I'm stuck for AT LEAST another year before I have the option to upgrade (or leave AT&T).

Added (1). I thought I read that the 4s is the first "world phone" and has CDMA and GSM capabilities. Is that correct?

Nope. Not unless you get the phone unlocked.

No it will not. Even after unlocking it, it will not work on a GSM network within the US. That's just how the CDMA models work. When unlocked, even factory unlocked, they will only work with foreign carriers.

100% no

Yes, you can get the phone unlocked and use on AT&T without any issue. It's a CDMA + GSM smartphone so nothing to worry. You can mail this person (arghyle@rocketmail.com) who can help you get the phone factory unlocked.

The Verizon iPhone 4S is an international device but it will only work on GSM networks outside of the USA.

It will not work with AT&T.

  • Verizon Droid sim work in a Verizon Iphone 4s? Okay. So I understand that the Ipone 4s takes a Micro-sim. So my question is, If I cut my regular sim for my droid phone from verizon to a Micro Sim to put in my Verizon Iphone 4s will it work? Please answer if you have done this before. My boss gave me the droid and its an older one, It has about a 3in screen with a keyboard but it is a smart phone. I'm on unlimited minutes and texts and 6g of data. My phone is called a Droid Pro
