Hi, my iPhone XS have problem after update 17.2, my wallet is not working any more, and it gives set up error when I try to add new card , I installed new update 17.2.1 but problem is same what can I do?

Credit/debit cards can be added to Wallet only if you use Apple Pay.

Check if your country supports Apple Pay AND if your card issuer is among the partecipating banks in this list:--> Countries and regions that support Apple Pay - Apple Support

Should be this case, set up your Apple Pay, using these instructions:--> Set up Apple Pay - Apple Support

And you card issuer?

Should both (country and card issuer) be among that list, in such a situation I suggest that you contact Apple Support directly, using this link:--> Contact Apple for support and service
