I am currently using BSNL ever since they launched bb, but am sick of them... They werent like this a few years back, but neither their speed nor service nor uptime is worth talking about. In short, anytime i have something important, i can rely on the fact that my bb wont work.. So am done with BSNL... Reliance is not avail unfortunately and Airtel is a touch expensive though I know for sure from a gauranteed source that uptime is brilliant! Suggestions please?! Currently looking at YOU as a possibility!
