Can I update my phone number and bank card at Bangkok Bank with a DTV visa?

When I go to the bank I dont even bring my passport, I just show them my driver’s license

Go in and try to do it. If they ask for something like a work permit or another requirement, tell them you'll bring it next time and don't return. From what I've heard they're not closing accounts unless you confirm to them that you no longer have the required documents to open an account.

Mine was not closed, they just told me I can't open any new accounts like term deposits. The account was opened 8 years ago with a proper O-A visa. I guess like everything in Thailand the branches apply rules with variations. It would help if you have a Thai known by them to assist you.

I had to go in to Bangkok Bank a month or so ago to set up the facial recognition and update my phone number as I got a new phone. I'm on a tourist visa and no questions was asked. I've had the account around 10 years. For information, this was at the Bangkok Bank branch in Central Festival, Chaing Mai

I have maintained bank accounts with both Krungthai Bank and Bangkok Bank for approximately 12 years. Both accounts were originally opened on visa exemption and remain active. I have also updated my information with the banks several times and travel to Thailand both with visas and on visa exemption.

Recently I purchased a new phone and visited the bank to update the mobile banking application. The bank declined to assist because I had entered Thailand on visa exemption on that trip. I tried several branches and received the same response. They advised that if I returned on a Non O visa they would be able to assist.

If you have not used your account in a long time (around a year or so) banks automatically close the account

consensus: AVOID all communications with your banks especially you are using bkk bank

Older accounts are the most likely to be safe.

I've read at least 3 posts about this same exact thing in just the last week.
