I am using aircel since 2013 . Aircel is very good for local calls and internet but std calls have bad network.
Most of the time when you are at roaming cost is very high. The internet speed is not so very high but compared to others the internet speed not very bad when you are in 3G cerles .The net packs value is very low to others.I use aircel prepaid connection and its very good .Thanks for support
