I upgraded my plan online to get more speed from 50mbps to 100mbps. But I noticed that I am getting the same speed of 50mbs on all devices. When I contacted the customer care they did a few troubleshooting steps.
And when it did not fix then he said I am sorry you are using it in wifi so on wifi we cannot give you 100mbps you will get only 50mbs because it fluctuates. Airtel is much better than this
