Cellular: The SmartTub® System incorporates alternative technologies in connected products.  The world of connected products is large and growing exponentially in many outdoor products that benefit from Machine-to-Machine (M2M) communication. Our exclusive design leverages the fact that hot tubs are located outdoors to directly connect to local cell towers.  We partner with major wireless carriers around the world to ensure stable networks with maximized performance.  SmartTub®coverage is not related to your personal cellular plan, managed for you and billed to you directly through the app on an annual basis starting in year two. M2M communication uses low bandwidth 3G technology to make a connection affordable and wide ranging. We use data packets smaller than a text message to remotely control and monitor your hot tub. Even when you don’t have sufficient cell service to stream video or have voice communication, your coverage will still support your SmartTub® System. Check the links to the coverage maps to verify coverage in your area.

The SmartTub® system uses cellular-based communication and requires cell service from our provider partner in your area. Verify coverage here:
