It provides great experience for those who are settled near the tower and not suitable for people who like to travel a lot as Tata Docomos network is poor compared to other service providers. I just ported to BSNL. But my experience with Docomo was good except for the network range issues. The offers provided by the Docomo is better compared to other service providers
I had a bad experience with postpaid connection of Tata indicom. And henceforth with that incident in mind I will never use any postpaid services speacially Tatas.
