Aircel is the weakest mobile operator of india in my opinion. I am using aircel sim from the past 2 years and even my family also uses it and I have a very bad experience with it. It has a very big network problem that does not come in some areas and call quality is also not very good. They are giving us 2g and 3g services but not 4g services in j& k. And the signal strength of 3g services is very bad. There service is very bad. They charge high rates for recharges and go good plans available. They are lacking in the field of network operators. I think they should improve their network problems and launch 4g services in future.
