If you are in Georgia and do not need to apply the 372 sim card any more and have it turned off, but somebody may contact you (for example your foreign friend), you can forward these calls to a number of any country in the world (including any number in Georgia).
To turn on the forwarding dial: *146*081*, then number in international format, # and OK.
To turn off the forwarding dial: *146*080# and OK.
For example, forwarding to a Georgian number: *146*081* 00995 XX XXXXXX # and OK.
Forwarding to Georgian numbers is free of charge.
Note: After forwarding , it doesn't matter if you leave the SIM card turn on or turn off and save it, forwarding works normally.
