BSNL 3G sucks.it doesnt have dynamic IP support that deprives you from using that for office VPNs, their call center guys don’t even understand this when you try to complain. I wonder how can this be a next generation technology when it doesn’t support dynamic IP addresses, and be sure BSNL 3G is only for browsing internet and NOT for working from home, Hence this so called grand old technology which they say is "NEWEST" sucks! The tariff is also not value for money as the starting price is 550 for post paid.
The network doesn’t really work in roaming as they claim though its reachable at various cities.
