No need to visit Airtel anymore.

Until now it was thought that there was no way to re-charge the data on an Airtel SIM with the pre-paid plans without going to the Airtel office. I've figured out the process that Airtel uses when you go there and it can all be done by ourselves. The only requirements are that you will need one phone that has Airtel Money activated on the SIM and a second phone that has the SIM from your USB dongle, hotspot or phone that you want to load with the data plan.
