The technicians on site for installation will confirm line of sight and serviceability before proceeding with the install. The card number that you enter to pay for the installation fee will be used to set up automatic monthly payments for service. Your card will be charged for the install fee, and first month after you are installed. Since service is month-to-month, you pay each month for your upcoming month of service and will receive an emailed receipt. Please call us at 970-460-8480 to change your card number or for any billing questions.
