Many (not all) use WISE for transfers.
Be aware that only 3 banks have higher limits...here is cut and paste..
"Wise has transfer limits of 2,000,000 THB per transfer to Bangkok Bank and Kasikorn Bank in Thailand. The limit for Siam Commercial Bank is 1,499,999 THB per transfer. For other banks, the limit is 49,999 THB per transfer".
Also note that if you are dealing with CW the SCB bank does not have a branch at immigration.
BBL cannot issue 12 month bank statement on the spot.
I use Kasikorn for those reasons alone..
The higher transfer limit is handy if you ever eg purchase real estate.
