BlackBerry forum: T-MOBILE BRANDED BB 8100 UNLOCK, PLS HELP!

Hi,

If you want to use your Blackberry with other networks, it can be done by unlocking your Blackberry from it's network.

Well, it's pretty simple actually... if you have the IMEI code you can buy online a MEP code that will unlock your Blackberry - you will need to insert a SIM card into the Blackberry while unlocking it.

Just get a code to unlock your Blackberry and unlock it once, then the network lock will be removed and you will be able to use your Blackberry cell phone with any GSM network carrier by inserting a SIM card to your Blackberry.

You can use any SIM card while unlocking it, of any carrier... even an inactive one.
After you get some sim card for the unlocking and after you have the unlock code to unlock your Blackberry Pearl (you can buy it online).

use those instructions:
