buying a new at&t cell phone?
hi my at&t cell phone broke, it has a 3g sim card in it, if i buy an UNLOCKED gsm phone will i be able to put my sim card in it and it work without me having to pay extra or anything?
Yes, as long as it’s not a smartphone. If you get a smartphone, AT&T will automatically add the $30 monthly data plan to your bill. Call them to verify this.
