When I get a quote from https://direct.axa.co.th/TA-Inbound/CoverageOptionPlan,
it's 2000 THB for 30 days or 3700 THB for 60 days for Plan 1 (the cheapest available). Might vary with age.

main exclusions:
3. Terrorism.
7. While the Insured is taking part in a brawl or taking part in inciting a brawl.
That means becoming a victim of a terrorist attack or a brawl is not insured!
It's different from insured "Medical Expense due to Accident or Sickness" but still, it's out of my power not to become a victim of a terrorist attack or a brawl.

Personal Accident Loss of Life, Dismemberment, Loss of Sight or Total Permanent Disability 1,000,000
It doesn't say which currency. The premium is quoted in THB, but this must be 1 mUSD as 1 mTHB is less than 50 kUSD. Does the contract you receive state this clearly?
