Hi, I have the same issue as the original poster. I am trying to buy and esim, all personal data being accepted, but failing at the final payment screen with the following error.
**
Error**
An error has occurred Please try payment again
I have tried both Mastercard and Visa options, Both from cards i have purchased items already in Switzerland remotely. None of my backs are contacting me to authorise any attempted payments as its not getting this far.
Datatrans is the payment partner that is being used.
