I can't add any card to my Apple Wallet

Hello, I've tried everything. I bought my iPhone 16 Pro in Argentina a month ago (and migrated from an iPhone 11). Previously, I was able to add a Banesco Panama card (from the bank's app), but now I can't. Likewise, I can't add any VISA debit cards from the Banelco network in Argentina. I've tried with family members cards, and it doesn't work either. When I try on other devices (iPad and different iPhones), I can add them. I previously had the Banesco Panamá card loaded in my Wallet (but never got to use it), and when I deleted it to add it again, the problem occurred. (I did this to verify that the issue was with Santander Argentina and not my iPhone, as I've never been able to add the Santander card, but I could add the Banesco one). Now I can't add either card.

The message I receive is: "Card Not Added. Contact card issuer for more information." I have tried the following:

• • Restoring from iTunes (both from scratch and with a backup)
  • Creating a new Apple ID account
  • Ensuring the region is correctly set to Argentina
  • Disabling "Content & Privacy Restrictions" in "Screen Time"
  • Resetting my password and Face ID
  • Changing my Apple ID password
  • Enabling the option to share device usage information with Apple
  • Deleting the card on all devices (previous cards)
  • Reinstalling "Wallet," trying to add data manually, holding the card close, from the app, and from settings
  • Changing my iPhone's region
  • Adding billing address information to my Apple ID (the same one the card uses)

Again, I was able to add the same Banesco Panama card to my iPad's Wallet. The VISA Argentina card (Banco Santander Argentina) issued by Banelco, I cannot add it to either my iPad or my iPhone in any way, but I can add it on other iPhones.

Perhaps the information Apple shares with the bank from my device flags it as fraud, and that's why the bank rejects it. However, neither of the two banks has the training to handle these cases; that's only seen in the USA.

The last thing left for me to try is to wait 30-45 days without touching anything related to Wallet to see if there's a kind of "whitewash" of a possible false positive for fraud."
