Alright my upgrade was not available so someone allowed me to use his upgrade to get a new phone. I have the phone on the way (mon/tue ). We are both on the same AT&T account. My concern is the SIM card it is shipping with because its under his line. Can I just call AT&T when I get the phone and have them activate the phone with my line? Is that something they can do remotely change info on the SIM card, or would I have to go to the AT&T store and have them put a new SIM card in?
