I am in Pune City. Airtel 3G was much better. Since when I have bought 4G SIM card. 90% time I dont get internet connection and many a times calls do not connect. Even changing setting to 3G or 2G do not make any difference.
And if you are traveling then forget about Internet connectivity. very disappointed with Bharti airtel 4G service. I think they should not have launched 4G in such a hurry. Only pro is when it connects has very good speed. goes even more than 1mbps while downloading.
