I tipped over my Jeep in February outside of Las Vegas. I had a Garmin Inreach mounted on the dash, but I was able to walk up a hill to get cell service. The local Jeep recovery folks were hard to reach and never got back to me (it was a Sunday). I spent several hours trying to get a tow company to come help me, and one eventually did.
With the stress level and back and forth activity involved, imagine a three hour constant workout according to my fitness watch, the Inreach would have been easiest. However, I would have been at the mercy of their crisis center. I could barely use the high level functions of cell phone, and occasionally handed it to my teenage son to do more complex tasks, like send GPS coordinates. My ham radio would have been out of the question, unless I had my frequencies set up in advance. A break down, where you could just camp? Sure.
