I come from Indonesia, as I know very rarely group bitcoiner's in whatssap, but there are some groups in telegram, unfortunately it's public group from every country. I am more often active in bitcointalk forums and local forums, to discuss bitcoin communities and investment plans, mining and the like.
Where in Indonesia are you from? My wife is indonesian.
Anyways, yes there are some telegram chatgroups but i feel the following of those groups are not really what i am looking for..?
I will pm you..
