Wise cards are excellent.
Have been using mine for 3 years now.
Only thing I find annoying is their low commission-free limits for ATM withdrawals.
Max 2 withdrawals/month for a maximum cumulated amount of 200EUR.
Anything above that is charged 0.50EUR per withdrawal and 1.75% on the amount of money withdrawn.
So let's say you wanna withdraw once a month 20000THB (500EUR).
You'd pay nothing for the single withdrawal, then nothing on the first 200EUR and then 5,25EUR on the remaining 300EUR.
Essentially a 500EUR withdrawal would cost you 5,25EUR which amounts to a little bit more than 1%.
Add a 220THB (5,50EUR) fee from the Thai bank owning the ATM.
Ultimately a 500EUR withdrawal would cost you around 11EUR - 2% and then some.
That said. A Wise card won't beat a Thai card linked to a Thai bank account receiving money from the West.
I don't think so anyway...
