I think those in New Jersey and Puerto Rico during the last hurricanes
there (2017?) would disagree.

Landlines went out, due to fallen trees taking lines down and because
POTS were no longer powered from the exchange, so stopped when mains
power was lost. Mobiles failed too, shortly after the hurricane had
passed by, because the backup batteries in cell towers were only good for
a few hours operation. IOW, they were sized and costed to cover
individual power outages but not for large scale disasters - and this in
areas that were prone to hurricanes. I've seen comments, too, that the
Puerto Rico telephone system has still not been fully restored to pre-
hurricane service levels, so well done Trump's FCC and the wonderful Ajit
Pai.

At least here in the UK most phone lines are underground.
