From past 5 years i'm a customer of airtel India.i have not faced any issues with these network earlier I was using normal sim, then I upgraded it to 4G which works really really good compared to another companies. It's network is awesome I can reach any where in India, internet speed is also good compared to any other company. The only one thing which makes me hard is it's tariff. Airtel always keeps it's tariff very high but after jio even they have reduced the tariff.
