Is AXA travel medical insurance coverage void if I leave Thailand?

Very good point Mr. Bertram. I don't doubt that what you say is true in the EU and Switzerland (where mandatory [?] health insurance already covers most everything. My Zurich associate's COVID travel insurance is $100 for a year while travelling outside of country).

However, in Canada this is not the case. Our provincial insurance covers only $100 per day in-hospital and $50 out-patient, reimbursed. Private companies without monopoly-protection charge much more than those of European countries equivalents.
