I just purchsed a new airtel sim but the service provided by them is worse.i couldnot use 3g data pack in our locality that is balasoe 756001. I just called customer care.they hardly took about 15 minites to receive my call. They told .e that your area has good network but I was unable to use 3g data at my home.i m getting one tower in my pgone.they even booked a complaint n told that they will contact me as soon as they solve the network issue. but they never called me. so I preffer you not to got airtel sim.worst service ever.
