Thread: Unlock Touch Diamond p3700

I have the Touch Diamond p3700 but it is locked to Orange and I am now on O2, is there any way of unlocking it? if so please tell me how. thank you

The best way to get an unlock code is by calling Orange. They are not required to provide the code, but sometimes they do {But they may charge for it}. There are no free options.
There are too many unlock code sellers located around the web, but none for free. You must be careful when purchasing an unlock code from an online service. If possible look for reviews for the code seller that you are looking at. Many of the people that sell codes online, are not using Official code generators. On occasion, the code provided is wrong, but this is a small number compared to the amount of accurate codes.
One of the best ways to unlock the device is by using an unlocker designed by Olipro. Olipro has been programming HTC devices for years, & has created a tool that removes the locks from the device. Many people have used this unlocker with great success. You can read more about it @ it's official thread: http://forum.xda-developers.com/showthread.php?t=414835

you can get the unlock code for your HTC model mobile, through this site Mobile Unlock Solutions - The Ultimate Website For Mobile Phone Unlocking
It has the easy instructions and some new methods for unlocking mobile phones.......

thank you lolly...
