My connection was activated on 14th. So, i guess my billing period should be 14oct-13nov, right? Can't i go over 50mb per day and compensate it the other day if i need to avoid the excess usage?, or is there a limit for a day? What's bsnl's criterion for all these queries of mine? I phoned to my exchange but their knowledge is limited. Instead of clarifying, they messed the whole things up!
