AT&T Prepaid Device with Current Plan
I'm going on vacation and don't want to bring my current iPhone. I would like to buy a cheap flip-phone (already ready for AT&T) and put my SIM in that (the SIM size is compatible). The problem is that the phone I'm looking at is "prepaid", and I don't want to get on a new plan. Can I buy it without a plan and put my current SIM in there without hassle?
