Unlocking AT&T T637


Nov 14, 2004, 8:11 PM
I have a T-637 that I bought when I signed up for AT&T with the understanding that it would be able to accept other SIM cards overseas...obviously it's locked and that's not the case. What is the best solution for unlocking this bad boy? Is there a simple code I need to type in or is it much more complicated? I tried calling AT&T and Sony Ericsson themselves to no avail. Thanks for the help!

The easiest way to unlock your T637 is with a Terminator dongle, or by using a T28 Unlock cable and a remote server credit.

If you are looking to just unlock one phone, then the T28 cable/credit will be cheaper, but if you plan on unlock and flashing a few phones you will want to definately get the terminator dongle, as it doens't require an internet connection and can be used as many times as you want!

good luck!

If you want to unlock your Sony Ericsson T637 mobile phone from the network lock,i would suggest you to get an unlock code from ... » at reasonable price by specifying the details like country name,current network provider and IMEI number.
