I have been using Tata docomo for almost 1 year.at the very beginning it was very good and even the prices were low for the data packs.
but now it has become a headache for me as well as my mates who use this as their operator.
talking about the speed on 3g mode, it is very much slower than any other network operator in my city.
the price of the 3g data packs has been increased too high for a common man to afford.
the network service also sometimes goes down for some technical reasons and requires a plenty of time to get resolved.
the customer care executives of this company are very much ill-mannered and doesnt co-operate with the customers at all.
I will be soon porting in to some other operator.
