If your Mastercard payment was declined during eSIM checkout, the most common reasons are bank security checks, incorrect card details, insufficient funds, online payment restrictions, or failed verification.
Most declined Mastercard payments are temporary and can often be solved quickly.
Quick answer: Recheck your card details, approve your bank verification request, and make sure online or international purchases are enabled.

Most Common Reasons Mastercard Payment Was Declined
1. Incorrect Card Details
Even a small typo may cause a decline.
- Wrong card number
- Incorrect expiry date
- Wrong CVV code
- Name mismatch
- Billing mismatch
2. Identity Check / Secure Verification Failed
You may need to approve the purchase through:
- Banking app notification
- SMS code
- Face ID / fingerprint
- Bank verification page
3. Online Purchases Disabled
Some Mastercard cards require online payments to be enabled manually.
4. International Transactions Blocked
Digital travel purchases may be treated as cross-border transactions.
5. Insufficient Funds
Available balance may be reduced by pending holds or spending limits.
6. Too Many Attempts
Multiple retries in a short time may trigger temporary security blocks.
7. New Device or Travel Location
Paying from another country or a new device can trigger extra checks.
