2025-07-23|Apple Pay for eSIM by WiFi Map app

I have bought eSIM many times, no problem. Today, I cannot pay! Here's the error message.

Apple Pay Is Not Available in "WiFi Map"

Check the settings for this app and make sure it was designed to use Apple Pay.
I switched to another credit card inside Apple Pay and tried again and again and again, but the same problem persists. Here are settings in WiFi Map app itself, and in Settings app > Apps > WiFi Map, respectively. There is no mention of Apple Pay anywhere. HELP!!!
Thank you very much for your attention.
