Airtel is also a good operator. But there was a time when Airtel is the best network among all other operators. So if it will start giving a good service again. Then again it will become a best operator.
Now a days Airtel gives a poor Internet service and also costly.
And no network coverage.
So therefore it must need to alter its technology and come with a change.
So I will note recommend airtel to any of my friends or relatives.
