How to Unlock an ATT Phone
- 1). Open your battery cover, remove the battery and look on the label underneath for your 15-digit IMEI (International Mobile Equipment Identity) number. If it's not there, type "*#06#" (no quotation marks) into your keypad, while powered on. It should display on the screen. Write this number down.
- 2). Call AT&T support at (800) 331-0500. Give a representative your IMEI number and ask for a free unlock code. Either you will be told that your unlock code will be sent to your email address, usually within three to five days, or you will be declined. If the latter, navigate to an online vendor, enter your model, carrier and IMEI number. You will be charged a fee for the code (see Resources).
- 3). Perform the steps indicated by AT&T or the online vendor when you receive your unlock code. This usually entails removing your old SIM card, turning on your phone, entering your code and pressing "Send."
- 4). Turn off your phone. Slide in a new SIM card and start anew with an unlocked phone and a new carrier.
