Hello guys I reviewed on airtel operator.Best network coverage in most city and villages too.I used airtel from last 5 year I used its 2g , 3g and now 4g service. With comparison of jio its downloading speed is too gud and calling clearity was too gud.Airtel 4g service is costly but happy to use because I love to watch video online beside downloaded.So it give me gud speed for surffering and buffering.Airtel network coverage is big like it has gud downloading speed in villages too.So when ever I went for my grandmother village .I have never suffered with its network for calling or net. Airtel is best operator for me.I am very happy after using it. This time jio is everywhere but I love too use airtel 4g becz it was best.
