Landline would be OK at least when it was a copper POTS circuit.
I'm now on fibre so my UPS would keep it up for a few hours provided 
that the remote exchange batteries hold up. VDSL is dead instantly.

Mobiles died doing ET phone home bleats once the local masts dropped out 
after ~30h. Now know to put then into airplane mode immediately to save 
battery. Mast transmit power drops when mains fails.

Fussy flat iPhone refused to take any charge from the car which was 
seriously annoying.
