I’m using bsnl mobile past 7 years during this period I doesn’t have any problems with network operations. I would like to recommend you people to use our government’s bsnl service. I promise that bsnl is the only network providing data plans at less and reasonable price. Mobile Internet service also very good compare to other mobile networks. Expect peak time both 2G and 3G service providing full speed without interruption of connection.
Voice and roaming charges also reasonable only here rate cutter are called as boosters or STV. Those also fine compare to others. The only network having network single anywhere in India even in rural area also we can get good coverage.
Only thing that I dislike bsnl was their customer service. Whenever you calling to customer service for help their response will be very bad even they don’t listen what your problem but not at all.
