It's worth discussing.
My wife had a cell phone long before I did, because it was necessary for
her career. It was a long time before I began taking it on rides, and
longer still before I bought my own. At this point, I take it because
there's no reason not to. And for a novice on a trip through the Alps, I
imagine it could be handy.
What I'd worry about is a form of risk compensation: "I know very little
about bicycling, but I can do this trip because I have a phone!" That
could get one into trouble.
Vaguely related: I saw a news article today about a man planning a 2600
mile ride to raise money for a cause. He's planning to ride 50 - 55
miles per day, not counting rest days. That's fine, if that's your thing.
But his wife is going to be following him the entire way, driving a
motorhome and pulling a trailer with spare bikes and bike equipment.
In 2003, my wife and daughter and I rode coast to coast, 4000 miles. We
averaged 56 miles per day including rest days. We carried all we needed
and never had a support vehicle. We had one simple flip-style cell phone
that very frequently had no coverage. I navigated by paper maps.
But hey, we're safer every year!
