Thanks ! Aha, so I think if you exchanged it to your savings, THEN you can maybe use it for international transfer ? (Is that option available to you when you tap on "view all" on the homepage ?
Kasikorn app: Home page > View all > scroll down to "international services" > International (y'r credentials pop up) > next > choose country > accept the statement > choose "Transfer with account number via SWIFT".
I tried this a couple of years ago with 100⬠also as a test.
For the test I only wanted to know if it worked. Did not pay attention on the cost because I almost was sure, IF needed, this would be a one time transaction. Maybe you can also test it once to be reassured. š
I did this long time ago as a test. This works ofcourse. But nowadays you can do it youself with the app. Kasikorn- and Bangok bank for sure. Other banks I don't know but think most of them too.
And why should you tranfer it back anyway ? SHOULD you want to leave Thailand permanently, you always can use the Kasikorn app for international transfer. Okay, it costs a bit more but usual it's a one time case only. And already said, debitcard works almost everywhere.
