I called many friends on #nostr and they also joined, but now they are not active on it saying that too much data is being consumed on Nostr.

That’s because of the relays. The more you have the more traffic you have.
You could advise them to use a more selective set of relays. That should help.
Or they could use it more on wifi, like I do. I don’t want to pay for all that mobile data.
This. Also usually on WiFi.
I'm down to 6 relays, now, because I include two broadcasters, and I'm building my own broadcaster, so that I can get down to two (my broadcaster and filter.wine).
What do you mean?
Few clients have low data mode
