Airtel is known for its best network.The mobile network range of airtel is very good across the india but its too much expensive plans cannot bear by a middle class person.Its data plans of 2G, 3G, 4G are too much expensive.Airtel can’t give quantity with quality like other mobile operators.So I switch to airtel due to its expensive data plans or call rates, other networks gives just doble benefits in same rates.So I never suggest for airtel in respect of budget plans or cheaper rate plans but in respect of data speed or network coverage I suggest the best network Airtel.
