I lockedmy phone with code (nokia 2630)am putting the code since yesterday but it is writting code error please i need the unlockng code i beg u please i we be very grateful if u can send me the code


The default lock code is 12345.

If you changed it and forgot the security code please contacts your device dealer. They will reinstall the software fully and they will bring your mobile to default security code so that you can open your phone.

NOTE: While reinstalling the software all your contacts will be deleted.

While reinstall the software, device dealer will ask for your personal details to check whether the mobile belongs to you only. If they are satisfied with your answers they will start the process.

The default PIN code is 0000.

If you changed it and forgot the PIN code please contact your service provider. They will provide you the default PIN code so that you can use your phone.

While you get the PIN code, service provider will ask for your personal details to check whether the mobile belongs to you only. If they are satisfied with your answers they will provide with the PIN code

This PIN code is FREE. You no need to pay any sum to get the PIN code

Thank You

There are lots of codes that we can use to unlock nokia mobile, but the most recommended code to reset the phone is *#7780#, but please note that this will reset all your settings to default while deleting all the phone memory. You can check out for more codes on my tips Nokia Mobile Phones Security/Secret/Unlock Codes.. good luck.

Asks me for a security pin when I try to "delete all" calls. I do not have one.

0000 or 1234 or 000000, these are the default codes for the shine. though through my experience servicing phones i will say that try each number on the keypad 4x's, 8's and 0's 6x's and 1234 most phones will unlock. also the last 4 of the # may work. without reseting your device or accessing it with software built to read the locks, you must try the trial and error method, and trust me, 95% of the time it works evertime!!! lol

Good Luck!!!

try deleting all BT devices in your list then try again....but that should work the 0000.

the error is coming from the phone so if that does not work then you may have to get the phone reflash
