I know calling *333 on your Reliance India Mobile and then waiting for a operator to get free so that she can answer your simple queries - this whole exercise is such a pain. Then
Reliance IndiaMobile Discussion Forums are there for your rescue.
RIM Services - Discussions related to Reliance Indiamobile services. (RIM Postpaid, RIM Prepaid, Miscellaneous, FWP/FWT, FLP)
R World - Discussions related to the much hyped 'R World' service of Reliance IndiaMobile

P.S.
I am not sure if these forums are supported by Reliance Infocomm but the users are very quick to answer your queries. The owner of the website just confirmed that the website is not associated with Reliance Infocomm.
