Hi everyone,
as some people might know Iam pretty much done participating in this forum. Nonetheless i thought this information might be helpful.
So after a few more months with my wife getting on the nerves of BPJS, the front desk worker (together with her boss) have finally been able to put my name rightfully in and I finally can use BPJS.
So I guess if you have the time and the nerves (in other places like Bali it sometimes apparently works more easy) you can still get BPJS as a foreigner on a spouse sponsered KITAP with no work.
My personal thoughts are that this is still about money. They probably just don't want to spend more money, especially for foreigners, if they somehow can prevent it. I also get this impression because I see how difficult it is sometimes until they give out rujukan/reference letters to see a specialist. I personally seldom visit the doctor, but my wife is another story. Sometimes it almost feels like begging until they finally give u what you need/want at the clinic. Luckily my wife has a pretty big mouth and is straight forward.

So yeah, my guess is that money is the problem here. An insurance like that is expensive for a country, so they try to keep it as low as possible
