常见问题
If money was charged but I never received the eSIM, how long should I wait before contacting you?+
There is no need to wait days. Contact us as soon as you see a completed charge with no confirmation email or QR code following it — the sooner you flag it, the sooner we can check and fix it.
How many times can I retry the same card before I should switch method?+
One retry is generally enough. If the second attempt with the same card fails too, move to a different card or channel rather than continuing to try the same one repeatedly.
Why does our decline message carry less detail than the one my bank sends?+
The detailed decline code returned by the card-issuing bank comes back to us in a limited form. Our system only sees whether it was declined, not the full internal reasoning the bank itself holds.
What should I do before buying if my card is close to its expiry date?+
Check the expiry date before confirming payment. If it is very close to expiring, switch to a different card or a digital wallet instead, since some bank systems decline transactions ahead of the actual expiry date.
What does it mean if no email about the decline arrives at all?+
It is possible the attempt never reached the stage that triggers a notification email at all — for instance, it dropped out during the connection to the payment processor. Check status directly through your banking app rather than waiting on an email.
Is switching to a digital wallet as safe as using a card?+
Both carry their own security measures, but the specifics depend on each provider. We recommend checking the terms and verification steps of the wallet you use directly with its provider. If the displayed price sits in a different currency than your wallet is denominated in, a conversion step can apply there too, just as it can with a card, and that is set by the wallet provider itself rather than by us.
