I have been using airtel as my mobile operator for about 3 years now. If it talk about the quality of calls its surpasses every other network, the quality of calls that this network provides, is better than every other mobile network available today in India and the Internet speed of Airtel is also the best, No other network even comes close in terms of speed to Airtel, there is only one thing that could have been improved and that is it’s charges. the price that we have to pay for using the Internet and making calls in this mobile network are not as low as they should be. yes, the price have decreased after the launch of Reliance jio, but still airtel has a long way to go. if you do not want to use reliance jio as your mobile operator, then airtel is the best choice available today. thank you for reading.
