What should I do if my Thai bank account is tied to an old phone and my DTV visa complicates app access?

You can install the true money app it has scan features same as the bank apps.

You csn top up the wallet of true money by connecting it to your existing thai bank account, this way you can easily recharge the truemoney digital wallat everytime and uae its scan for everything 😀

Another great benefit is that true money also enables free digital master card credit cards so you can use it for all the online payments and add it as a legit credit card for all the common apps such as Grab, Bolt, Lazada and many others.

Remember that you always have to male sure you have sufficient money balance in your truemoney wallet for payment when you use the credit card or for any scan payment.

If balance too low just recharge it instantly by topping with the bank account you connected to the app.

The other alternative is to top up (recharge) using cash at 7 Eleven or dedicated truemoney money machines, there are multiple ways and options to recharge it, don't remember all of them.
