Depending on the currency of your account and the type of plan you’ve chosen, there are different limits for how much you can top up and on how many top-ups you can make in a certain period. You can see full details of this in our limits section here and our Terms and Conditions here
The limits are calculated using a rolling window method, which means that your month time period starts from when you top up, not the first day of the month.
