prepaid phone that I already own.? Ok, so I have tmobile prepaid and a basic phone. I still want to keep the prepaid because I can't really afford a monthly contract. If you go to tmobile prepaid, there are about 6 phone choices and the nicest one is a out dated camera phone. If I'm gonna spend the money, I'd rather get a nice one that like. So can I go to like a tmobile retail store and buy a phone (nonprepaid- just regular) and then take my sim card from my old prepaid phone and put it in my new reg. phone? I was thinking this would work cuz they wouldn't know what phone you had it you had the current number and same sim card data. I'm pretty sure this would work, but I want to be sure before i buy one. Thanx
