In a world where people need to bug out, I doubt a cell phone or satellite phone would be an asset. Where it would be useful is if someone needs assistance and can hit the satellite.
My truck has GPS navigation. When I drive to town in between mountains, there are areas where the GPS positioning icon stops moving. When the connection is reestablished, the icon jumps forward from where it lost the satellite to where it reacquires it.

Yea I visit a few places like that, my GPS is is a handheld, but can also vehicle mount Garmin Montana 650 with backroad maps installed .
The Zoleo is for when I'm backroading and have an incident

If the Zeleo works, you live in the flatlands. Here, there are lot of shadow of a mountain dead spots. They knock out the GPS and also the satellite FM radio. The cell phone can't hit a tower until we get a few miles from town.

It wasn't until the last upgrade to my truck's Nav system does it show the road I live on instead of "off road" in the display.

Very rarely do I get into a shadow like that, If I do I'll relocate the few hundred meters to fix the reception issue.

You live where it is flat; so tunnels and bridges etc. could be a problem.

After I put my antenna tower up; I plan on adding a Weboost cell phone booster on it at 30' or 40'..

Hilly, mountainous but not many deep sharp ravines.

As they were the easiest place to build a road years ago, most old roads here go through valleys. They began as dirt roads when vehicles were powered by animals. Later, they were paved.
Today depending on the direction of travel, those areas are shadowed from satellite reception.

When there is a mudslide on I-40 west of Asheville, travelers are advised to ignore their vehicle's GPS and follow the detour signs. I've overhead gas station clerks warning travelers to follow the detour signs and ignore their GPS.
