Reliance 3G speedtests earlier in early 2011, I did this to check Reliance's network congestion after the company rolled out 3G@2G plans. I was using 1GB data plan for Rs 123.
I used several servers - some Indian and some overseas. Reliance showed awesome results with most Indian servers, while the overseas servers get good enough performance.
How to check 3G data balance: send MBAL to 55333. You will get instant notification with remaining data usage details.
