Have you tried the above yet? Try it.

I fail to see how it would help, the issue arises when I try to use a payment portal like there is for caixa bank transactions, SMS is a valid way for me to sign in to my account, but not to confirm a payment.

And if that doesn’t work contact their customer service and say you don’t have the option to use another device and you need to set up SMS verification or you’re going to have to consider another card. I bet it will work.

I would have to disagree with your take, their customer service is 80% ai and 20% call center, none of the people you would talk to care or have the power to answer a threat like this.

I appreciate the ideas, but at the moment I don’t see a way of getting around my issues.
