What are the consequences if I can't link my bank account to my phone number by the deadline in Thailand?

The Thai government has mandated that bank accounts must be linked to a phone number registered under the account holder's name. If you fail to meet the deadline, you won't be able to access your mobile banking app, but you can still use your ATM card for transactions. If your phone number is not registered under your name, it's advisable to update it as soon as possible at your service provider, and subsequently at the bank. It's worth noting that accounts may not be immediately suspended; banks are expected to begin suspending non-compliant accounts only in June, giving some leeway to those in the process of updating their details.
