If your CVV code is not working during eSIM payment, the most common reasons are entering the wrong security code, outdated card details, saved card mismatch, typing errors, or bank verification issues.
The CVV is the security code on your card used to help confirm online payments.
Quick answer: Re-enter the code carefully, check the correct card, and make sure you are using the current active card details.
Important: Final payment approval is controlled by your bank or card issuer. Order processing and delivery follow our General Conditions.
What Is the CVV Code?
The CVV (Card Verification Value) is the security code used for online purchases.
- Usually 3 digits for Visa and Mastercard
- Printed on the back of most cards
- Used to verify online transactions
Why Your CVV Code May Not Work
1. Typing Error
The most common cause is entering one wrong digit.
2. Using an Old Card
If your bank replaced the card, old CVV details no longer work.
3. Saved Card Mismatch
Autofill or password managers may insert old card details.
4. Wrong Card Selected
If you own multiple cards, you may be using the CVV from a different card.
5. Virtual Card Refreshed
Some virtual cards generate new details and the previous CVV becomes invalid.
6. Browser Autofill Error
Stored payment data may be outdated or incomplete.
How to Fix CVV Problems Fast
- Delete autofilled payment details
- Take the physical or active card and re-enter manually
- Check all card numbers match the same card
- Use the current expiry date
- Retry once carefully
- Use another supported payment method if needed
Tip: Manual entry is often safer than autofill when a CVV error appears.
