Airtel shows the server speed of 460.8Kbps but the downloading speed is 22-30Kbps. It costs about 15 Rs per day with unlimited download. So it is about 465 Rs per month.
It can be connected to PC.
If you wnat to buy NOP then it 2 Rs per day but limited downloading.
But still if you want Gprs connection then i recommend Airtel than any other network.
pingtest tends to show much worse results than speedtest.net, and as a result, I just don't use it. Maybe in six months when AT&T releases WebOS for the Pre Plus, I will be able to really test the speed from my phone.
here is what I got just now. I live in prescott az. Now where 3G is brand new for sprint. I know it was much better in mesa az. If you take your score and divide by 8 you get KB/s. So mine would be around 59KB/s.
