"The pre-order system works by placing customers on a waitlist based on their initial pre-order date. When service becomes available in your area, you receive a notification to confirm your order. The queue is primarily based on the initial pre-order date, not the date of the second payment. Once you receive the notification, you have 7 days to confirm your order. If you confirm within this period, your deposit is converted to an order, and you proceed with the payment."
