Treat WeChat Pay as your second payment rail. Check identity consistency, card controls, SMS access, and app account state, then keep Alipay and cash ready if verification does not clear before departure.
You are trying to add a foreign card to WeChat Pay before going to China, but identity, SMS, or card verification fails. You still need a backup to Alipay.
Do not assume WeChat Pay is mandatory for every visitor.
Do not assume a new WeChat account is stable enough for payment immediately.
Do not hide Alipay or cash just because WeChat Pay nearly works.
