Here's what you need to use Apple Pay in supported regions:

• Your eligible device1
• A supported card from a participating card issuer
• The latest version of iOS, watchOS, or macOS
• An Apple ID signed in to iCloud

Perhaps you may find a solution in these links in Apple Support Communities:

1. No Plus Sign on apple wallet - Apple Community
2. No plus sign on Apple wallet - Apple Community
3. No plus sign on wallet - Apple Community
4. No plus sign in apple wallet - Apple Community

Please refer to Set up Apple Pay - Apple Support

You are welcome.
