How will I set limit to the usage of internet (per/mb) a day?

[Sulfuric Acid]

I have a BSNL Broadband with a download speed of 1.66 Mbps and 0.39 Mbp. It is the 9th day of the week and I only have access to 20 Gb per month, the extra I use, the extra I will have to pay.

I have already used about 13452 Mb and only have 7028 Mb left.

So I can use only 369 Mb per day, till the end.

My question is, how can I set a limit for the usage ?

You can not. Just remember that every page you view is a download, flash based pages are a continuous download, pages with streamed or flash scrolling images are continuous download, so are games.

I advise getting unlimited internet its cheap only around £25 a month for 30 download.
