Airtel has been fooling it's customers about 4g. At my home 3g runs faster than 4g. This is because 4g mode doent get full network coverage.
Speed on 3g is arround 350kbps. But on 4g ? I dont get any speed . They need to improve a lot on it.
Then comes the call quality which is at times horrible. They charge a huge amount from us but still only advertisemen. In real life they are awfully suffering. 1gb 3g costs 250?. And we netizens use atleast 4gb data a day. Even if we have wifi at home still we will end up in consuming 4gb minimum of mobile data a month. And that will cost a minimum of 800.
