Which type of card does the 900 use? If it's Micro-SIM, my current SIM card will not work, so how will I go about getting my number onto my new 900?
But in order to get LTE on the phone, your need an LTE Micro SIM (different) and your IMIE needs to be setup on AT&Ts LTE network. They can do that in the store.
