I have been using Airtel for a long time and I was very happy why the services and the network coverage with is very high in my area and the company phone calls are very low so it does not disturb me a lot recently had about open network so I called Airtel and tell them how I was happy with this facilities so it is a good mobile operator and I suggest you to experience it because the network quality is too good and the data usage in the 3Gor4G network are very well the schemes of recharges is very good so that anyone can easily afford it and use it properly for long time.
