Almost always by your bank rather than by us — a foreign online payment for a digital service is exactly the shape of transaction their fraud rules stop first
We never see the reason. The bank answers the payment attempt with a refusal and no explanation, which is deliberate on their part; the fix is therefore at their end, and it is usually quick.
The Usual Causes
- Foreign or online payments are blocked on the card, sometimes by default
- The 3-D Secure step was not completed — a confirmation in the banking app that timed out or was dismissed
- Billing details do not match the address the bank holds
- A daily limit has been reached
- A typo in the number, expiry or security code
What to Try, in Order
- Check the banking app — many refusals arrive there as a notification waiting for approval
- Re-enter the card carefully, including the billing address
- Try a different card, or a wallet such as Apple Pay or Google Pay
- Call your bank and ask them to allow the payment; it is usually authorised while you are on the line
A pending charge on a declined payment is not a charge. Some banks reserve the amount while deciding and release it within a few days. If you retried several times, you may see several reservations — none of them are collected, and no eSIM was issued for them.
If a payment succeeded but nothing arrived, that is a different problem with a different answer — see How Quickly Will I Receive My eSIM?, and contact support rather than paying again.
