Did you get a new SIM card and need to activate it with AT&T? Activation is just a phone call away, as long as the person calling is an account owner or retail authorized user. A retail authorized user is a person who calls to activate your SIM when you go into a local AT&T store, and this often happens behind closed doors when you purchase a new phone. If you purchase a new phone from AT&T, the SIM card will be included and already activated, so you don't have to worry about this process! This wikiHow teaches you how to activate a new AT&T Wireless SIM card.
