Hai guys am using bsnl sim since 5 r 6 years I never seen such a worst sim, very bad signal strength even if we call to bsnl sim people always it says phne is not reachable right now. Voice breaking, no offer on recharge if no offer customers can’t attract to recharge. Coming to net speed 3G sim but working as 2G sim no use at all just name as 3G very slow net comparing all sims.
