Can I withdraw money and manage my Kasikorn Bank account from overseas?

Can use ATM and online bank facility I had no problems in Oman and UK

Like he said but remember you’re going to get the lesser conversion rate from Thai to your home country money.

Yes to both

I don't know about the ATM so I can't answer that.

You can only login to the kbank app while you're in Thailand. If for some reason the app resets or you get a new phone or whatnot, you'll lose access to the app.

You can register for online banking at a bank branch but it's not included by default.

I think I've seen people say you can have OTP e-mailed to you so you could ask about that. I think for phones they can only go to Thai numbers so you'd need to keep your Thai number if you wanted to receive OTP that way. Just turn off data roaming before you leave Thailand.

The regular debit card you use to obtain cash from a Thai ATM will work (you may have to apply for overseas use from their call centre).

Most banks now have an app that allows you to control your account from that. I’m with SCB so am not familiar with Kasikorn.

If using the app you don’t need OTPs just your pin for the app or facial recognition if your phone has it.

There online banking app is great and easy to set up I use it for oayinfmg for everything more or less

I use my online banking for kasikorn in uk and I have used the card in airports around the world over the past 2 years
