I cant begin to tell theproblems with the airtel network. I had a postpaid connection with a 1GB plan active. I hardly ever got 4g connectivity but even then somehow my internet limit of 1 Gb used to get over within a week. No alerts or messages are sent about the usage and you are stuck with a huge internet bill at the end of the month. was forced to port my number to idea which was also a lengthy process.
