A way to (un)lock your cell phone on to the network(subset):

1. Press <**< style="font-weight: bold;">Warning: 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!

Alarm Clock Menu

Go to MissedCall Empty the list Press the -> key for a second or two The option Menu size turns up Choose 'yes' and go from there.

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

Free phone calls using the GA628

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!!
