AT&T iphone with verizon sim?

I have a verizon phone and an AT&T iphone. Can I lit the verizon sim in the AT&T iphone and have it work?

I don't think so, the phone must be unlocked. Just try it anyway…

Absolutely not…

Verizon uses CDMA technology for their towers where AT&T uses something called GSM… The phones are not compatible…

It's like trying to play a PS3 game on an XBOX… It just doesn't work because the phone feeds off the towers differently

  • 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
