There are only single good thing that roming is free but about networking there are many problem as calling when some one call me than mostly time saying that not reachable and service is very high. Any types of plan as calling plane msg pack data pack is very high. Customers services is also normal and net speed is not good . Also net is going for two or three days. I think that bsnl try to provide good service compare to other company. Because this is a government compnay so try to provide good service and networking.
