OP, is located in Bangkok.
In recent times you require a residence certificate to open bank account.
He cannot obtain a residence certificate at CW unless he is doing 90 day reports there.
Regarding banks.
With recent changes to some banking rules in Thailand WISE can only transfer funds greater than 50k to 3 banks.
Bangkok Bank , Kasikorn and SCB.
SCB does not have branch at CW.
The OP imo best to pic one of the first 2 banks.
