Hi Guys, So I was able to score an iPhone X today for in store pick up (Sure beats my December Delivery). Anyways this is a gift for my mom. I used her number for the upgrade, However my father paid for the firsts month payment and fees on his card. I am however an authorized user on the account ATT account. I shouldn't have any problems picking up the phone today should I? The only thing I saw on the order page was that I just had to be an authorize user. Thanks again for the help!
