Hello,I am wondering whether there is an authoritative list somewhere on the web (TRAI perhaps) that lists the various numbering levels assigned to the different mobile providers.Some are, of course, easy:92 - Tata93 - Reliance94 - BSNLBut what about the others, the early comers, when they were all clubbed under 98. (I see Airtel now also has 99.)One should be able to tell the provider by just looking at the number.All help appreciated.G. Amik
