It's pretty easy really if you have a Thai bank account.
I'm on a non o visa and I'm with Kbank which I set-up with two accounts so one for my 800'000 to season and my other account for the
*****
Thai baht per month to pay my bills etc.
Im from Australia and I use an app now called Smartway which I found personally better than Wise and Remity to transfer my money.
I mainly use the QR code now at the shops and the supermarkets just like a local which is super convenient.
I only get money out of the ATM if required.
