I am an airtel customer since last 7-8 years and its network coverage is very bad . there is full network outside my home and when I go in house I have network problem whenever somebody calls me they hear the number you are trying to call is not reachable. Airtel’s network coverage is very bad I recharge for 3G internet and even after paying for 3G I got speed like 2G. no proper network coverage, no speed as per offered in data plans. I contacted customer service center but no change in the network problems. they are not fixing my problems slowest network ever
