If i already have a phone beside at&t subscribed can i just put my sim card into an iphone?
Answers: No i option but you have to hold a certain plan and you enjoy to plug it in to itunes to put into action it.I believe you can, I am not sure though. If you want internet you will need to capture a plan for the iPhone.
Check out Mobile2Mobile. There is an area a short time ago for the iPhone! http://s11.invisionfree.com/Mobile2Mobil...Yes you can Sim cards are transferable tru other cingular phones
Yes, you can. Any phone that works with Cingular will work near your SIM card. It's just a thing of putting it into the phone.
