Apple Pay using debit card - suspect fraud
I am using iPhone 13 Pro Max.
I am not from the US but when I travel in the US, I am unable to use my Apple Pay for payment at certain locations using my debit card.
I noticed that the payment is often successful at restaurants and online payments but declined for public transport and supermarkets. I have been resorting to payment directly with the same debit card which has been successful.
I had contacted Apple support on multiple occasions. At their suggestion, I had upgraded to the latest iOS 18, changed my region to the US. In addition, I had deleted and readded my debit card.
However, I have not resolved my problem so far. In my last call with Apple support, I have been informed that I cannot use another debit card from another region in the US. This has been very frustrating for me so far because I know this is not true.
Has anyone experienced this issue or knows how to resolve this? Thank you.
iPhone 13 Pro Max, iOS 18
