And this is why you still need a "wired" home phone (POTS or wired broadband).

I an constantly warning friends and relatives about the unreliability of cellular networks.

Depends on what is causing the outage, at some point all wired and cellular calls are transported over the same network, it’s how you access that network that’s different, one is wired and obviously one cellular.

If the core of the network is down, then both networks will be down.
