Does At&t Sim Card Work For Verizon. I do have a tmobile SIM but honestly havent tried it I have unlimited ATT. Just dont forget to back up your old iPhone so you can restore the new one with your apps and pictures and stuff.

Putting ATT Simcard in Verizon Phone. The SIM card in Verizon Wireless phone are used to access their 4G LTE network. But I dont have a Verizon SIM to try.
Yes you can put a Verizon SIM card in an ATT phone.
The Nano SIM acts as the fourth generation 4FF of SIM cards measuring at 123mm x 88mm x 067mm. All you need to do is push a paper clip into that small hole on the right side of your phone and the sim tray will pop out. I havent had to use the online switch system for close to five years now and I have switched phones over a dozen times since. The SIM card in your verizon phone is only good for roaming on others networks and this usually only happens when you are outside the country and verizon has a roaming arrangement with one.
