Noy doubt that airtel is trustable network since from 10 years in India but it is only good as calling network not for 4g because its plans are too expensive and also that it provide high speed only a week or less after that speed getting slow and connection get weak. Moreover it is not avialble in many village that means the speed of 4g is low more . Airtel required to improve connection of 4g and provided more benifical schemes . It is trustble but now days it broke there trust. As 2g nd 3g its very strong but as 4g it get weaker.
