All of our membership plans are month to month and require no contract and no credit checks! Each payment pre-pays for your next 30 days of membership. You may of course cancel your subscription with us at anytime by simply returning your device to Nomad. Monthly charges will continue until the device has been received. Additionally, our 14-Day Money Back Guarantee allows you to try our service at No Risk! If the service does not meet your needs in any way, simply return the device for a complete refund of your entire order! How awesome is that?
