@Nilgiri how we can get data about what is total bandwidth of Pak, Ind and Ban? How much is currently used by each one.
Bro, getting specific number would need summation of ISP + Mobile data providers large scale data. These are generally behind a paywall or they are not released at all for compliance with privacy laws of countries (is what I have found, but maybe others can dig better).
Surveys done by others for these tend to be limited in scope (IP traffic sampling) and also behind paywall.
We can do a rough " max-frontier" analysis using sites like this one you might find interesting:

https://www.itu.int/en/ITU-D/Statistics/Pages/stat/default.aspx
Something like you take: average speed of (mobile) connection * average time spent on web per day * 365 *number of (mobile) internet users
Per user its roughly equivalent for the region (speed tends to be around 10 MBPS for all 3 countries according to ITU). Average time spent a day per user for India is around 8 hours a day, I would assume same for other 2 countries. The total users using internet is around 35% for India and around 15% for both BD and Pakistan in 2017 (according to ITU). This has changed for India to around 45% in 2019 and I would assume its also increased considerably for Pakistan and BD in 2019.
I use (mobile) because (fixed) broadband penetration in south asia is quite limited (around 1% of total population according to ITU, but that was 2017, so could have increased now)
The actual final demand number would be normalised as some % of this given average browsing habit per user (i.e you are not always loading pages 100% of the time you are online etc).
So would this frontier analysis really be useful? Its up for debate. Maybe later I will try digging if any specific GB numbers are there anywhere. I read somewhere just now that the average smartphone user
in the world uses about 7 GB of data a year. But again thats a very vague somewhat useless number for use in south asia analysis.
