For newly added top-up cards (including replacement cards received from your bank), you will have a temporary top-up limit that allows you to add a certain amount of money per 24 hours. Some users may find they have a lower daily limit to begin with, however, your daily top-up limits will increase over time and we can't change these manually for you. Try and top up your desired amount. If you wish to top up more than your daily limit, you can top up by bank transfer.
Other than that, there aren't any specific top-up limits. On some occasions, we may ask you to verify your source of funds, which is something we need to do to meet our regulations.
