I have used all the service providers and found that aircel is the very worst network provider in my place. if I go inside my home my mobile will become not reachable as no signal will come to my home even though the aircel tower is near to my home.
There are more disadvantages of this network than advantages like no proper connectivity, net pack rates are high, roaming cost is high, no offers to the mobile.
As I was using the prepaid number the billing is not there for me and also the rate for call is also high.
