Welcome to the largest cellular network in india and yes most costlier too. Airtel has best network in india I have used many other networks but using airtel for almost 5 years, you can literally find network everywhere in the country, its net is fastest like **its 2G is almost as same as 3G of others**. But it is the most **costlier networks** and call rates are also much higher. Overall it is worth it’s price. Plus customer service is also better than others.
