Airtel is a good telecommunication company.
Airtel provides best offers for its customer and also has good internet service.
The best 3G cellular data is of Airtel, but in terms of 4G it I am unhappy with it.
Airtel tell us that we have 4G but its worthless. In India Airtel provides only Band 40.
If someone has a device with 4G enabled and does not have Band 40 than its worthless, it means Airtel 4G is useless.
This is my experience, since I have Lumia 625 it supports Band 1, Band 3 & Band 7. So Airtel 4G is useless for me.
Note: I am talking about only Airtel 4G not any other services.
