Airtel has come up with a new 3G scheme that carry forwards your 3G prepaid balance if recharged before the pack expires. The recharge has to be done via airtel online recharge portal. I had around 800MB of Data left in my device and then recharged Rs 102 which added up 300MB to the tally and the total usage was brought to 1200 MB, another good part is that it takes into validity of your new recharge.
How Airtel 3G Infinity works:
Suppose you have a 3G balance of 500MB left and the validity is just one day then you can recharge Rs. 102 which will increase the validity by another 28 days and also add up to the previous 3G balance bringing the total free usage quota to 800 MB.
This new offer from Airtel is extremely beneficial as you won’t be losing your 3G balance due to the validity issues.
