actually the whole transfer of credit thing was available from before...read your sms again it says " if you run out of credit you can request your friends to "CALL YOU" by dialing the above number. Not sure how that works but i think you can make that kind of call even without credit and your friend will receive may be a sms saying to call you back. Havent tried will wait till i run out of credit lol
