All - I use the app on iPad almost daily and once got the same message as OP. My particular reason

Is used for US Social Security retirement deposit and defaults to this account. Quick click on other account and no issues.

You can reset your pin and get a new one at any Bangkok Bank ATM. Or keep waiting I guess, might still come one day.

I've done this twice at a branch office without issue. Once for lost card and once for new Tele #.

Once I had a transfer problem message as the OP named. I called and pretty quickly got a person who checked the account I was trying to transfer to; it didn't exist. Turns out the vendor, a very prominent dental clinic in Huahin, printed it wrong on their cards and was embarrassed. So the problem wasn't with the bank at all.

 

I'm glad the OP found a browser that Worked but I've used several browsers with no problem. TIT.

Did you try dialing 1333 on a mobile phone and using their English language customer service?  I haven't found the menus to be very difficult to navigate and can talk with a real person fairly quickly.

Ditto, always found their help lines very good when you eventually get through to someone.

The post I quoted said Internet banking. You are able to reset your password for Bangkok Bank Internet banking at an ATM, I've done it. ATM PINs are never done by SMS which is what they told him to wait for so he was obviously not talking about his ATM PIN.

 

 

Thanks for that. I see it now. I can also see why I (and others) got confused. The term PIN is used for bank cards. To access internet banking you use a PASSCODE. Use the the right term and you elicit the right response. ????

I’m not a techie but have been advised to clear the browser cache to (sometimes) fix a problem. Apparently browsers hold on to certain data to pre-load pages to speed up processes.

My French ISP likes to block Thai banks.

Most likely the other way around. 

Been using for 4 years, had need to ring twice, no long wait & problem solved on the spot.

Some posters on here talk rubbish. 

If need a new pin or change a visit to any BKB with correct ID  will have done immediately.

Wait 2 months,,,,,,skypilot
