If I purchase a Iphone 6S Plus from someone that uses AT&T as their provider can I purchase a new sim card for it to use with me verizon account. I currently have a 4S andI don't think the sim I have will be compatible with the 6S
The ATT iPhone 6S is compatible with Verizon's network if it has been unlocked by ATT. You can get a free compatible SIM card from a corporate Verizon Store. The SIM card in the 4S is not used for Verizon access, so you can't switch it to the 6S.
Thank you for your help.
