Looks like BSNL is the worst choice in Kolkata. Today I was in my cousin's place and his ISP is AWESOME. He gets about 150ms for EU and 230ms for NA. I could play in both servers. It's called Meghbela/PMPL Broadband. If I can get that here then I will ditch the BSNL Dataone and only keep the phone for intercom etc. Will let you know when I know more.
