, you can bounce at a land border, by air, or so-called sea border.
Bring printed Non-OA (if eVisa) and a new insurance policy in hand to enter Thailand for another year. Make sure to check the entry stamp before you leave passport control that you are stamped in for 365 days (or insurance validity) with "Non-OA" in the "visa class" field on the entry stamp.
