I found Airtel as worst Service Provider, No Network Coverage most of the time, Using Airtel 3G but other service provider’s 2G runs fater than it. and Charges High and Customer Support nil. I will not Suggest Airtel for any new user.Raised number of complaints. no use. It Does not deserve Evan a Single star.They are trained to fool you saying there may be problem with your mobile.I am using Lumia 730.still I get issues. I find personally Airtel as Costly Network provider.
they are not interested in resolving the issue. The data packs are costly as well.
