Free is free and paid is always better than free. Guys I am talking about the Jio which is good company but the service is worst on the other hand Airtel which is known for its best service either calling, 2g, 3g, 4g. Airtel, one of the leading mobile network operator of india, the customer service of them is really awesome. The main drawback of airtel is that their call rates are much higher compared to others. The network will be available at many places. Totally airtel is very good except that its services are much costlier compared to others.
