eg: LINE bars the use of GV numbers as does Discord. It used to be possible in GV's early years to make a call from your American GV number while in another country but seems to be no longer the case.
Or maybe I'm made a hasty generalization. I've used my GV number for years, including with line, and I still make calls from wherever with it, but maybe that's because of its age and that it was ported from a regular cell
