As the competition continues, Airtel brings you a very cheap data plan but this time around it only works for 2G Network (EDGE).
With N500, you can get 4GB data which will last for 28 days and with N200, you can get 2GB which will last for 14 days.
To subscribe for the 4GB, dial *483#
To subscribe for the 2GB, dial *482#
The above data plans works on all devices but only using 2G Network. If you want to use 3G Network, you will have to subscribe to a normal Airtel data plan.
