Ok i am looking to buy an unlocked iPhone. I am currently with AT&T but still have a cingular sim card(not sure if that matters). I am aware that when you purchase a iPhone through AT&T you must get the data plan which is like $50 more. I have unlimited texting on my plan currently. My question is can i use an unlocked iPhone with no internet or data plan and still keep my current bill the same? I know it may sound stupid not to want the internet on the iPhone but it is useless to me, i would never use it. I just like the phone itself. Any help would be appreciated. thanks.
