Airtel is the worst mobile operator till date that I had used and I know other people would also agree with me.i had personally used airtel and I can say that its d worst in the market now.whether it be network coverage or anything , its simply only a joke! The network coverage is very very poor and at times I find the other netwrk operators giving better coverage den airtel.also nowadays the drop rate of calls have increased .inspite of such netwrk problems still the call rate and rechrge bills are very high .datswhy I suggest airtel is not appropriate fr use of common people
