You can contact customer service to see if they will unlock the SIM for you so you can use it in a different phone. Call 611 from your cell phone or 1 800 331 0500 from another phone, state "more options" at the first menu prompt of the automated system and then say "customer service" at subsequent prompts;after a few the system will connect you with a live rep.
They do have some requirements and they may not unlock it for a brand new customer. You can also obtain a replacement SIM at a Corporate at&t store if customer service won't accomodate your request. If you'll add funds to the account while in the store, they will likely not charge you for the replacement SIM, and they can provision it with your existing account information/phone number/balance.
