Wherever possible we'll try and send you just a single unlocking code to unlock your Sony Ericsson TM506.
However for certain models we may need to send you more than one code, even if you don't use them all.

It would be a sting of codes as per this example:

CCK: 0984118338439652 or 0984118346911861
ESCK: 0000000000000000 or 0000000000000000

Note: The NCK (Network unlocking code) is the main and usually the only one you'll need.

Please note:

- If you see the message 'NCK: (0)' or 'Not Allowed', this means the phone is hard-locked. The phone cannot be unlocked because there has been more than 5 wrong unlock attempts.
