I am from Pune and am using Reliance netconnect+ unlimited prepaid plans.

Rs 800/- for one month. 5Gb on HSD speeds and thereafter unlimited on 1x speeds.

Upto 5GB I have no complaints. The speed is good. Max of 1000 kbps. Normal of 700 kbps.

But when the 5GB limit is crossed the problem starts. I expected a lower speed, but there were many other problems. The link would get disconnected every 4-5 MB of download. google.com was not visible. When I tried to reconnect the error came "an authentication event has occured". I need to reconnect 4-5 times before a connection is given.

The nett effect of this is that 5GB of downloads happened in 11 days. And in the next 10 days after that only 60MB of downloads happened with the same time at the computer.

This ultimately is not a complaint. It is just a warning to the rest of the users that the unlimited package is in practice just a 5GB package. You will not get any joy after that.
