How long have you been with ATT? Are you on a family plan with your parents?

What about the unlock services? Idk anything about them and some are scams but I know some people use them successfully.
I'm currently just using airplane mode + wifi = no calls atm. I've been using whatsapp or a equivalent to keep in touch with family.
+Thanks! I'll loook into the study abroad plans and see if it would be worth it rather than getting a local plan..
I'm in a family plan with 4 lines total, we've had a cingular plan before, switched to verizon recently, and came back to at&t. The only phone on contract is mine, and everyone else got second-hand phones. I've been paying for my iphone 5c for almost a year, on the NEXT plan?
