I was thinking about Whispernet too, and then I thought about Sidewalk, and how some cable ISPs are offering wifi hotspot service via the router they rent you (Comcast does this). Would manufacturers need to add cellular support if they could instead sign deals with other companies to auto-setup a wireless connection? I realize Sidewalk is very low bandwidth, but I wonder if that's a problem for the telemetry data we're worried about.
