Tata docomo mobile operators provide poor service on only North India some special city like Meerut Bijnor Gaziabad Delhi NCR.Network remove again and again any where in North India.So my experience very bad with Tata docomo.Only 3G Network Received some special place and 2g some network available every place so 2g coverage very good similarly other network.Consumers services is very slow and very comfortableAnswering time period very long time.Best Bill payment : - Recharge plan available very low prices in market and give others benefits like more enough data and calling plan others network.Thanks
