Aircel is very bad networking operator.beacause 1st thing it don’t have 4g network and data and download problems in smart phones.no towers in some cities thats why it takes help from another network like idea, reliance.And do not works properly when I need to do important work.they should improve their network and signal problem in many cities.customer care takes call but they even talks very nicely.some time they do not solve the problems.and takes many different reasons.
