I am using aircel since 2014 I dont have any issue.aircel also provide new offer daily and it gives full talktime on recharge the best thing about aircel is free calling at 1rs you van talk unlimited from aircel to aircel.
At just 1rs but one thing is not good about aircel customer service they are always busy in calls we have to wait for an hour for connecting them and all is fine with aicel I suggest you to go for aircel.
