Reporting latest experience. Yesterday transferred the monthly 65000 baht from my Australian bank account via Wise (Funds for longstay in Thailand) to my Bangkok Bank account. Transfer initiated at 9:40am, funds arrived in Bangkok Bank account sometime between 12:30 and 12:50pm correctly noted on the account as an international transfer, for immigration purposes. Transferred funds for rent and internet at around 1:30pm. Used QR Promptpay scan four times between 4:00pm and 8:00pm.
At 2:30pm ordered 12-month statement from bank app (for immigration purposes this coming week), which arrived via email at 4:30pm.
I'm on non-O retirement extension, BB customer for eight years.
Absolutely no problems, account not frozen or suspended.
Bangkok Bank and Wise not quite the ogres which some are suggesting!
