Range/coverage is spotty in most of the country outside of city centers, just because I have a phone connection doesn’t mean I have a strong data connection and even if I have an LTE connection it doesn’t mean it’s moving at streaming speeds, even in the middle of Houston my data can move slow as molasses.
Unlimited data that’s truly unlimited doesn’t really exist, my carrier limits me to 100gb on cell data before throttling and dedicated wireless internet is again capped at 100gb. So my cell phone would eventually be used up in the truck assuming I’m in a place that would reliably get cell service.
As a result most people have satellite service on their trucks for internet and TV, dish network is like $400 for the hardware and 50-$100 a month depending on what package you have. Do you really think truckers are watching their football games on the tv that’s streaming from a cell phone? No there’s a little Dosh or wine guard radome behind the cab. So having the option to put starlink into a truck when trucks literally already have satellite service is nothing new, in fact it’d be better, could bump down from the $50 cell plan to $35, take off tethering, then run the cellphone on WiFi while in the truck and hook up the TV to WiFi for Hulu, Netflix, sling, etc.
