Unable to add card to wallet

Please make sure the device (iPhone) you're having issues with is updated to the latest iOS, 16.5.

Update iOS on iPhone - Apple Support

Check that the region the iPhone is set to supports Apple Pay.

Countries and regions that support Apple Pay - Apple Support

There have been posters here in this community and Reddit that have resolved the issue by removing the card on all devices (Mac, Watch, iPad, iPhone), updated, restarted and were able to add the card back to all devices. The downside would be the card can’t be added back to any device. Have you contacted Apple Support in your region?

But the card was able to be added back to iPhone? You removed from all devices right?
