Please airtel users PORT ur number to some other network when u can send SMS. This is my 5th day I can't do anything with airtel prepaid Sim. Contancted 121 4 times, visited showroom 2 times but no use. They are saying everything is OK your no in our system. I tried all the options they suggested to do. Showroom people even can't resolve it.
