If your credit card transaction is declined, it could be due to the following reasons:
- 3D Secure Requirement: MobileSMS.io requires 3D Secure (3DS) authentication to protect against fraud. This feature sends a one-time verification code to authenticate the transaction. If your card doesn’t support 3D Secure, consider alternative payment methods.
- Consider Cryptocurrency:
- Cryptocurrency payments offer an easy and private solution if your credit card is declined. Supported options include Bitcoin, Ethereum, Tether, and others.
- This option is especially helpful for users who prefer an additional layer of anonymity or are facing regional payment limitations.
- Contact Your Bank: If 3D Secure is enabled on your card but the transaction is still declined, contact your bank to ensure there are no restrictions on international or online transactions.
For further support, submit a ticket in the Help Center, including details about the declined transaction.
