Where I live in Agra aircel network strenghth is worst however in some parts of Agra its good.but its risky because you cant rely on a network when its coverages varies highly, you may endup getting a great network or no network when you need it.
Cutomer service of aircel is ok but what they can do when its about network.
Previously charges of aircel were cheapest but after jio , aircel charges does not seems to be that cheap, however still in 2g segment its cheapest.
Overall its bit risky to try aircell but if you stay at a place where aircel network is good and you dont move from places to places you can try it.
