I have been getting 200 kbps CONSTANTLY on Airtel.
I have the limited edition Airtel SIM card which has UNLIMITED (no questions asked) Internet for Rs 199 a month.
This price and this speed is unmatched for EDGE.
When my Vodafone 3G SIM is inside, I do get speeds in excess of 3 MBPS wherever I am in Mumbai. At home, I do get in excess of 4.5 MBPS and the 1 GIG that I get free from Vodafone can expire VERY fast if not used judiciously!
