Was trying to add my Savor One card to both Samsung Pay and Google Pay. For Samsung Pay it was added, but then when I was trying to verify it via their mobile app, every time it said "We hit a snag, please try again later.
With Google pay, there is process to add it to Google pay to pay online, but not to the phone. Every time it just said: "You added too many cards, the process can't be completed". The card was previously added to both Samsung and Google Pay.
I called Capital One support, they say you can't add your card, when overseas, only when you will be back to US. There is no other method to add a card to mobile wallet, only using mobile app verification.
Capital One are such an idiots!
PS. Connecting with VPN helped. Idiots anyway. You can't add a card to a wallet without using their app.
