Airtel one of leading telecom service provider in india.
Actually it was my fvrt provider til last few months.
Now there is lots of network problem.3g speed is not upto the mark and 4g btr we don’t talk about it. But it totally depends on ur location. In some places airtel service is great.around avadi in Chennai we can get 3g speed upto 2 mbps.it had great covarage there. So its 50-50 totaly depends upon ur location.
