Unable to test Apple Pay with Sandbox account

Hello! I'm trying to test apple pay integration on my mobile app. It's working fine on a simulator now I'm trying to test on a real device in dev environment. I've followed every single step in this guide:

Apple Pay - Sandbox Testing

After I logged in using a sandbox account on my iPhone device, I was not able to add any test card to my wallet, when I click on the "+" button it is showing below prompt:

How can I create a working tester (sandbox) account to test apple pay functionality?

Even I faced the same issue. Resolved it by changing the device to a country(Settings -> Media and Purchases) and region (Settings -> General -> Language and region) that supports Apple Pay.
