Are you sure you have a global expatriate health insurance with them, not a global travel health insurance? It sounds like the latter since it excludes your country of residence.
I asked for a quote in accordance with our 30-year old “Typical Nomad” persona and the quote is for €2,421 per year. That’s in line with the most expensive ones listed in the article (e.g. Allianz)—which makes sense since their ACS World plan is in fact powered by Allianz.
EDIT: I checked and their Globe Partner insurance is indeed just travel insurance which is limited to a maximum of 12 months.
