You can make free phone calls with GA628 (also work on other models)
NOTE: This trick has only been reported working on PREPAID GSM CARDS and in some countries and with some software versions.
The prepaid GSM SIM CARD is a kind of “SIM card” which only has a certain amount of credit on it.
Here’s the trick: Dial the number 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.. I hope!!
