Americans, do you have a problem using Discover cards on SBB Mobile App?

[misnelstain5]

Hello,
Of course I have contacted SBB and Discover about this; this is only a question for the meantime.
On the SBB Mobile app for Android: I attempt to add a payment method to purchase my ticket, and get error 1403. I am using a Discover card, and Discover is a listed accepted credit card on the app. My Discover account does allow Swiss purchases.
I'm wanting to know if you have this problem, or especially a solution.

Hello @misnelstain5 

Thank you for your query.

Unfortunately not all foreign credit cards are accepted due to security regulations. I recommend you to contact our specialists by mail: ticketshop@sbb.ch.

Kind regards,
