I had used airtel mobile service and internet for 8 years. Airtel got strong network coverage, tariff offers and excellent service. I never had an issue with network coverage or bad service. The customer care service is also very excellent. Online charge facility is also available with very good service. The 2 G and 3 G service is also good from cost point of view as well as amount of data credited and validity. I was new to 2 G when I started internet use in my mobile in 2008, the customer care executive assisted me in getting internet in mobile. Airtel is trustworthy and excellent and I wish to go with Airtel always. Just need to extend their full coverage throughout rural India as soon as possible, it’s there but need to strengthen.
