What you have to do is to flash the phone, to flash the phone, you use the 3 button flash system.

1. Turn off the phone:
2. Press and hold the dial/green button, *(star) key and number 3 from your key pad at the same time,
3. Keep holding it as you press the power on button to switch on the phone and make sure you do not release the buttons,
4. A page will pop up like a formatting page, do not release the buttons until the formatting page is complete,
5. Then your phone will be back to the way it was when you first bought it.
