Hello,I had a chance to talk with one of the top officials of BSNL, who is in dataone section. I asked him regarding how the above mention case is handled. If he is to be believed, He told me they have a timer in place, running at each 15min interval to record the usage to a seperate log. so freetime and paid time usage will be handled seperately.Btw, I don't take the risk, I always disconnect and reconnect at 7.55.Shaplus
