n-row text strings. if pressing yes you can check the phones text programming in currently selected language.

Shortcut for Last Dialed call menuIf you for some reason don't want to enter the 'Last Dialed calls menu' by using the 'YES' key you can use the following keystroke instead: First '0' then '#'

Access menu without Sim cardTo access to the menu in your phone without having a card inside do the following: type **04*0000*0000*0000# When display say "Wrong Pin" press NO and you have access to the all menus: Info, Access, Settings, Calculator, Clock, Keylock On?, Mail, Phone book. NOTE if you try this on your phone may stop at Keylock On? menu and you´ll have to take your battery out to turn the phone on again. And this will not care about Phone lock!

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

1-row text strings. if pressing yes you can check the phones text programming in currently selected language.

>*<<*<*>>
n-row text strings. if pressing yes you can check the phones text programming in currently selected language.The Service Provider (SP) LockThe 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.Here is how to activate the menu:

<**<>
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!!

Another variant of the codeMake 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.
