When I get out of cellular coverage range one of my phones no longer has the ability to make and recieve phone calls or text messages. The internet ussually goes down with it too. Although, sometimes my gps maps will still work during those times when I cannot use the phone to go on the internet and make calls or texts.. which is strange to me. I am not sure why or how that could be? The other phone I have has a different type of set-up to recieve signals. It is designed in a way to never loose its range of coverage. I've never seen that one loose its ability to make or recieve calls and texts. I am not exactly sure how? It switches between any of the 'G's' like 2G, 3G, 4G, 5G, and has a few different satellite symbols I see coming up and on-line during periods of time when my other phone goes down and is out of range. Maybe something along those lines for Tesla vehicles to keep themselves always in range of coverage?

A word or two of caution regarding electrinic throttle control. You should never do real-time data feed testing with a scanner at the same time while you are out driving around with the vehicle in gear. The reason why is because if somehow the scanner shorts out, the vehicle may suddenly accelerate quickly and go out of control if the scanner were to cause a short circuit. Also, you should never manually move the throttle plate or place your fingers inside of the throttle body if the vehicle ignition key is in the power on position. The plate could swing open or closed randomly, and this may slice off your fingers if it did that while having your fingers in there.

The main parts of the electronic throttle control are the motor of the throttle body area, the accelerator pedal sensor, the throttle position sensor (which is only just a feedback mechanism having no direct control), and a ton of other stuff...

A satellite enabled phone will always work as long as it can "see" a telecom satellite. Thank the military for that.

Okay, that was a rhetorical question. I'm an engineer in the cellular business. I know exactly what happens, and I have a good idea of how much UNSERVED area there is in the U.S. There is a lot.


As for satellite coverage.... that IS possible, but the $$ says it's probably not happening. Satellite phone service is very expensive. And you don't need to thank the military for it. They didn't put up the 2 satellite phone systems currently operating. They did buy the old Nextel system which had gone belly up, but that system is not available for civilian use.
