SM-G9350 Hong Kong: anyone been able to access service mode menu, NETWORK CONTROL,etc

I need to test a way to get rid of a huge battery drain that happens when using a data only sim card..

Both *#0011# and * # * # 197328640 # * # * are not working.

*#0011# is only giving me basic information no network menu.

* # * # 197328640 # * # * is not working at all

There is a blog post in japanese, that using Google translate I was able to read that changing a setting in
MAIN MENU [1] DEBUG SCREEN → [8] PHONE CONTROL → [7] NETWORK CONTROL → [3] SERVICE DOMAIN → [3] PS ONLY fixes my problem.

This problem is present on all android devices, all of them are showing as 100% no signal when in fact they work but only in data mode (no voice).
There is absolutely no way to get a voice sim card in japan if you are not japanese.... (law, yes really).

The phone is not rooted because I want Samsung pay if it ever works in this device.

I reported this bu both to Google and Samsung
