The Service Provider (SP) Lock menu is used to lock the cell phone to the SP's SIM card. Once the cell phone is locked to a specific operator, if one inserts a SIM card from a different operator the phone will refuse to accept it!
The cell phone will however accept another SIM card from the same operator.

To activate/deactivate this lock one needs a special secret code that is not available to the end user. (not even to you... or is it ? in case please let me know!)

Here is how to activate the menu:

<**< Lock to Network? if pressing yes you have 5 attempts to enter NCK.

<**<< Lock to Network subset? if pressing yes you have 5 attempts to enter NSCK.

Warning: Your phone can be locked to a service provider FOREVER by doing this! If an invalid code is entered all five times, the menu will exit and be deactivated!
Any further attempt to activate the NCK/NSCK lock Menu will result in the response "Not allowed"! However the NCK/NSCK lock can be recover through a direct clearing in the EEPROM.

Free phone calls using the GH688!!.. 

This trick has only been reported working on PREPAID GSM CARDS......
so if you haven't got one of these it's probably not working....

The prepaid GSM SIM CARD is a kind of "SIM card" which only has a certain amount of credit on it
(like a normal phonebox telecard)... if it can be traced? - I don't know!...

Well..here's the trick you dial the no. normally and press YES. While "connecting"
is shown on the screen, the following procedure should be carried out:
Press CLR then 0 then # and then NO (twice) so as to switch OFF the phone.
You can then still speak on the phone while it is switched off but the
SIM card does not record your calls which will lead to FREE phone calls in some countries.. we hope!!

If you can make the call with the phone turned off you will face a problem when
you need to hang up the phone...the only way for you to do that is remove the battery.
