Thinkware doesn't offer a plug-and-play LTE module or dash cams with built-in LTE connectivity. In other words, Cloud connection relies on third party hotspot devices. You can definitely use your phone as a hotspot for your dash cam, but that would only work if you continue to keep your phone inside the vehicle, even after you've parked.
Because of the that, Thinkware Cloud is more suited for tracking the vehicle while it's on the road: geofencing, strong impact notifications, live GPS tracking. So, if you are a parent or a small business owner, then the Thinkware Cloud can help you monitor your vehicle and driver(s) on the road.
