I am using TATA Docomo for the last 3 years and I am really satisfied with the network, they provide cheapest 2G internet planes and also best calling rates.
The network coverage is also very good in my city. Docomo give many special offers. I didn’t face any network problem while in village as well. I’m using Docomo 3g service now and its very fast.
It is a very good network comparing to others. I would definitely recommend this network to others. Wonderful Network.
