ORIGINAL POSTER

I hope this falls I to the everything else category. 

I have been in the UK since April and have had no issues with my Bangkok Banking app for the three years I have had the account. Today I tried to open the app and was presented with the message below. I am somewhat surprised because I bought the sim card I use in 2019 and opened my bank account in 2022. I certainly did not use anyone elses name to get either. I have rung the number and spoken to someone about the issue and they say I have to go to my local branch to sort it out. As that is over 6000 miles away I explained it wasnt possible! I also explained that now I am unable to pay my rent or for utilities and other things. He told me he would look into it and would contact me within 5 days by email. I dont hold out much hope. I also need to transfer money back to UK as the cost of living here is horrendous and I cant return to Thailand until October. 

Has anyone else had this situation and found a way to get around it from abroad? I am aware that it has happened to others but I thought I was safe as I had both sim and account in my name?

TLDR : Answer Summary

An expat has shared their experience with accessing their Bangkok Bank app while in the UK. They received a message preventing access due to possible discrepancies between their SIM card and bank account details despite both being registered under their name. Commenters discussed similar experiences, suggesting contacting the mobile provider for verification certificates and relaying that information to the bank, noting recent stricter banking regulations that require updates to prevent access issues. Several users emphasized the importance of resolving these verification discrepancies to regain access to banking services.

Is there a way to check the name registered in our Sim by ourselves?

Same happened to me. I updated everything at the bank in April. My wife went to enquire about this at the bank. They told her she couldn't help me as I would have to return myself...what nonsense as they sent a confirmation to my back in April. Really dumb Bb.

Go to your SIM card shop and ask them about the “for the bank” certificate—they’ll know what you mean. They will give you a certificate (there’s no fee at DTAC, but I’m not sure about other SIM card shops). This certificate is a requirement for your SCB account (usually SCB is the one affected by this) or possibly other banks. Then, go to your bank and submit the certificate from the SIM shop along with your passport and passbook.

I saw some comments saying they paid at DTAC just for a piece of paper. But at Fashion Island Mall, I didn’t pay anything.

Yes this is due to their changes in rules and regulations. This is due to notices that been going out to verify things on your account.
