Common Deposit Errors and How to Fix Them
Most deposit failures at Prime Casino fall into one of three categories:
3DS authentication failure - your bank requires you to approve the transaction in their app or via SMS. If the 3DS prompt does not appear, check your bank's app for a pending authorisation notification.
Bank-side limit reached - some UK banks apply daily or single-transaction limits on online gambling payments. If your deposit is declined, check your bank app settings; many now include a gambling block that can be toggled off.
Incorrect card details - make sure the card number, expiry date and CVV match exactly. Even one wrong digit causes an immediate decline.
If none of these apply and your deposit still fails, use the live chat (available 06:00 to 00:00 GMT daily). The average wait time to reach an agent is 1 to 2 minutes.
