Im a airtel user its network coverage is average in nature .But recently new efforts done by the company after a massive hit of reliance jio is really remarkable, new packs with better quality of network coverage at a cheap affordable rate is really cool.Customer service is good when we call to 198 quick response time.Airtel ineternational packs are really good, specially the international incomming free one and as a airtel user I recommend its a good and trustable global leding network.
