Hi Subbu,

I don't think this is qgis related.
The plugin just uses other tools to download data from osm-api server.

If I convert your bounding box to decimal degrees:

78.7667 11.4167 10.3667 78.00

I get the following message from the plugin:

Download failed: Download process failed. OpenStreetMap server response:
Bad Request - The maximum bbox size is 0.25, and your request was too
large. Either request a smaller area, or use planet.osm.

It's just that the OSM server does not want to provide al this data via
the osm-api

You can either get small boxes of 0.25x0.25 degrees but it is easier te
get a data set from mirrors like:

http://download.geofabrik.de/osm/asia/

there are a lot of other mirrors for that:

Additionally, you can directly download areas larger than 0.5X0.5 degrees from the xapi interface, explained here:
