Airtel is the largest network provider, Its network coverage is awesome. I am using Airtel for last 4 years. Airtel has well behaved and nice customer care executatives. They help the customer politely.
All the services given by airtel is world class. It has mind blowing internet speed .
I have never seen such a great mobile operator. I am loving to use airtel . The charges of airtel for services is little more but it gives awesome service. Overall, nice mobile operator.
