Probably the new Star in telecommunication.Shot to fame only because they are offering 4G for 3 months free.And it is pretty useful.The speeds are far better than Airtel 4G around my place.Havent got issues while using it.The speed ranges according to location.Not much high speed at my college which is kindly remotely based.
The rates are affordable .Mostly same as others.
Service is far better than other competitors.If they fix the range issue in all remote places then this will be widely used.
