I am sharing my experience with bsnl network provider.
Before 2 months I bought bsnl sim in rs. 126 in rajasthan . I got rs. 100 balance which is gud deal. Network is gud. After 10 days I recharged rs. 14 for 70mb 3g but I couldnot received net and I lost my 14 rs. I tried to custmer care but couldnot reached. Second day I recharged with 78 rs. 1 gb 3g for 5 days but couldnot received 1gb data and again talk to basl after many time trying they give me lolipop and I lost again my money then I broke my sim and threw in dustbin.
