IMEI unlocking is the simplest way to unlock your phone. The IMEI number is a unique 15-digit identification number for your phone, which is displayed when you press *#06# on your phone's keypad. The IMEI is also printed on the back of your phone, usually underneath the battery.

Once you submit your IMEI to us, we will retrieve the 8-digit unlock code for your phone via a remote database and send it to you by email. To enter the code in your phone, simply insert a different SIM card (from any network but the one that your phone is locked to) and enter the unlock code at the prompt.

Once your phone has been unlocked, you will never need to enter the code again, even if you upgrade the software (flash) or hard reset your phone.

Unlocking frees your phone to work with any GSM network in the world. It will remove the "Enter Subsidy Password", "Contact Service provider" or other "locked phone" message and allow your phone to accept SIM cards from any network.

Advantages of unlocking your phone include:

• Allows your phone to be used on any GSM network in the world. Avoid expensive roaming charges.

• Frees your phone to use SIM cards from any network.

• Increases the resale value of your cell phone.

Please note that the unlock code is not the same as a phone security or SIM card password sometimes set on phones. Such codes are user-set codes that are meant for preventing unauthorized access to the owner's phone. The unlock code prompt will only appear when you try to use your phone with a different network (i.e. other than Cingular AT&T). Almost all AT&T phones are locked in this way.
