Please help me about this issue. Right now my phone is running latest version. I’m trying to add my cards in wallet but I can The problem is always showing contact your card issuer for more information

Have you contacted your bank and asked about this? This error message is part of provisioning and verification process that your bank and Apple go through to add the card to your Wallet. The bank that issued the card must do the provisioning and verification of the card.

Have you been sent the terms and conditions and agreed to them? This all happens within the Wallet app?

OK, great. After you agree to the terms and conditions Apple sends the T&C ID and the 3 digit CVV security code, and certain information from your iPhone. The bank then uses this information to decide if they want to approve adding the card to the Wallet app.

There are two things we can try. But usually this is a bank issue (or Payment Network). If you’re using a VPN it must be turned off, software deleted and profile removed.

Please follow this path,

iPhone > Settings app > Privacy & Security > Location Services (top of screen) > Location Service ON > Wallet > While Using App and Precise Location ON

If those settings are correct, you can try resetting Network Settings.

Reset your network settings

If you're using iOS or iPadOS 15 or later, tap Settings > General > Transfer or Reset [Device] > Reset > Reset Network Settings.

If you're using iOS or iPadOS 14 or earlier, tap Settings > General > Reset > Reset Network Settings.

This also resets Wi-Fi networks and passwords, cellular settings, and VPN and APN settings that you've used before.

Are you trying to add your card to Apple Wallet app, Apple ID Account or both?

Exactly what? Please answer the questions I asked so that I can offer the correct instructions.
