The fact is that with POTS the phone service was assured for days
even in the case of a full power failure, and now with the
replacement, be it fibre or cellular, service is not assured. For
whatever reasons.

Many people could not phone emergencies with their mobile phones.
Just a fact.

WHAT?? Did ALL the mobile phones' batteries immediatly go FLAT?? Or
Did that Batteries in the Comms Towers go FLAT??

-a Having been in one major disaster, it's the towers
-a that fail. They have generators, but if you cannot
-a refuel the generators ...

From what I have read, here most of the towers inside the cities have batteries (lasting 4 hours). If they serve some emergency infra, like
near a hospital, a police centre, they also have generators. Some may
have nothing if not considered important enough. And out of the country, batteries are not mandated. And it is not only the antenas for the
mobile network, it is also the links between them, and other links that
may go down. And the whole thing had never been tested, obviously.

Then batteries have to be maintained periodically.

My mobile phone kept working the entire day because I got coverage from
a tower at an old exchange, so it had a big generator. Many of the FM
radio stations failed. I forgot to check AM stations; I would have
needed to test on the car radio.
...

The old rules requiring 2-3 days of battery power backed up by diesel generators should be applied to the mobile phone networks. It is
understandable that the mobiles were exempted when they were new, and we
could fall back to POTS in an emergency, but now that POTS landlines are disappearing that will not work anymore. But I am fairly sure that the
industry will see to it that that cannot happen.
