Additional verification via the app or SMS is only required if considered necessary.

Please follow these steps if the 3-D Secure page asks for the SMS code but you have not received it:

1. Request a new code directly via the payment screen.
2. Check that the mobile phone number registered for your client profile is correct and is able to receive SMS messages.
3. Make sure you have network coverage for your device.
4. Check that the number is correct in the app or the online client portal («How do I check the 3-D Secure settings for my payment card?»).

If the number is incorrect, or if it is correct but you have not yet received a code, please contact the 24-hour helpline on +41 91 800 41 41.
