i saw a good phone on amazing that i wanted, its my same carrier. can i buy it and just switch my SIMS card into the new phone? or do i have to bring it in to the at&t store to get it regestered... its also a phone that you have to pay a monthly fee for..
I have the LG Xenon, and I want to switch phones. Could I simply take my SIM card out, and go to Target/Walmart to buy a Go Phone from T-Mobile or Verizon? Or would it have to be a At&t go phone?
