You can pay conveniently with a credit card or debit card. The monthly rental fees are automatically debited from your card on the day of your order. You pay the first month at the time of ordering, more precisely as soon as it is accepted by us, but you must only send back the device on the day it arrives at your place, to make the rental fair.
You can update your payment method for each subscription separately directly in your customer account. To do this, go to the relevant device under subscriptions and click "Change payment method".
