The Service Provider (SP) Lock
The Service Provider (SP) Lock menu is used to lock the cell phone to the SP's SIM card. Oncethe 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.
Here is how to activate the menu:

An alarm clock turned up too but it never rang. I think this was because there is no clock in the phone.

This trick has only been reported working on PREPAID GSM CARDS and in some countries and with some sw versions.
The prepaid GSM SIM CARD is a kind of "SIM card" which only has a sertant amount of credit on it (like a normal phonebox telecard)... if it can be traced? - we 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!!
Another variant of the code
Make a Call, while the phone says Connecting type 083# (the position 83 must be empty! ), when phone says Pos Emtpy, press the NO key and turn off the phone.
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...???
