You can buy credit directly through the cambio app using giropay.
In the my cambio portal, you can see the amount of credit available to you. If this isn't enough for a booking, you can purchase additional travel credit via giropay, increase your credit limit, and then make your booking as usual.
Our suggestion: Use the price calculator before holiday travel. This helps you ensure your credit limit covers your planned journey. Buying travel credit can streamline the booking process, especially if you're a frequent cambio user and unsure if your next booking will exceed your credit limit.
