Hi there,
You would have to purchase an unlock code for your phone. For the orange UK blackberry pearl, you can purchase the unlock code from our website if you'd like.
Just navigate through the unlock code menus and select the
BlackBerry 8100.
After the unlock code is generated, an e-mail will be sent to you with full instructions on how to unlock your phone. After that, all you have to do is insert any
SIM card, and your phone will work great
