So you have explained why a bank account is necessary. Great. Now can you explain why a THAI bank account is necessary? My US bank account is perfectly sufficient for living in any of the 8 countries I have lived in - including Thailand. US debit or Visa card works just as well in thailand as any other. It's not hard to find cards with no foreign transaction fees. Likewise, my bank charges no ATM fees AND pays the other bank's fees. I can think of zero reason I'd ever need a bank in thailand. Even if you want to hold thai currency, you can do that with revolute or wise.
