I do not want to buy health insurance, as the one I bought the first time, was absolutely useless I found out. The insurance company would not cover an incident as they should.
The travel insurance is much better. They do not ask for prior conditions. It covers home transport if needed. They cover theft on top of that. And lastly - it costs baht 15.000 for 6 months.
I just realised that they will see my stamp from from the O-A, which is valid for a few days after I arrive!
