What is the best bank to use in Thailand for a dtv visa holder using a UK card?

HSBC UK has two world debit visa and master cards , they can be used in major thai banks ATM

The master one which link to UK multi currencies account (including Thai bth in uk account, if you have there ), without handling free when using major Thai banks ATM

The visa one also can be linked , has a better exchange rate if you don’t have bth in uk account, but need to pay 250 Thai bth handling fee with Thai ATM (whatever withdraw 100 to bth)

Cheaper way is to bring cash and exchange in Thai SuperRich

Best way but complicated is to exchange pound to bth by FX broker, then withdraw into above cards linked acoount.. no spread in exchange rate, way better than wise and revolut

Easiest way is the ewallet , like True Money …. 7-11 also accepted

Btw you might want to ask the bank as many of staff don’t have idea of above debit cards

I got mine visa in UK as well as master in HK

Revoult or wise

Is card linked to visa or Mastercard or union pay etc? If so, you can use card at any ATM in Thailand

Revolut

If you stay longer it does not mean that you are automatically subject to Thai tax, there are many other factors too
