Entering unlock codes

When you receive unlock codes for your phone, they will look like some symbols followed by a long number and then some more symbols. There is only one unlock code for most handsets - as soon as you get the "phone unlocked" message and can use a SIM from another network in the handset, you can stop inputting unlock codes.

You can only have five failed attempts before your phone removes the option of being unlocked. For this reason, as soon as you get 3 "code error" messages, stop entering unlock codes. Your phone may already be unlocked, so test it with a SIM from another network. If it is still locked, then we recommend you take it to your local GSM dealer who will have to unlock your phone for you.

There are some special characters in unlock codes. These can be generated as shown below:

Leave a short pause after entering any of these to allow your keypad to reset.

If you have more than one unlock code, try them one by one in the order give. As soon as your phone is unlocked, you don't need to enter any codes; if you do try, you will only see "code error".

To use an unlock code, first turn off your phone and remove your existing SIM. Then, turn your phone back on; you will probably get a "SIM not inserted" message. Ignore it. Leave your phone for a few seconds to boot up, and then simply enter the code digit by digit using your keypad - you should see it coming up on the screen. Check the code very carefully as you enter it, and double-check before pressing the last button - you only get a limited number of attempts!

Once you press the lass button, a "SIM lock removed" message - or something along those lines - should pop up. If not, go and try the next code.

If you do see a "code error" message and you're 100% sure that you entered the code correctly, go back and double check that you have chosen the correct handset and network. If any of these are even slightly off, the correct unlock code cannot be generated.

Good luck!
