Howdy! If you often use toll roads, it is most convenient for you to pay using Sunpass services. To do this, you need to purchase their transponder, which is installed on the windshield of your car, and payment will be made automatically. You can buy such a transponder from many retailers, whose contacts can be found on the company’s website, or you can call the sunpass phone number and the transponder will be delivered to your home within a few days.
