So... what exactly is the crisis scenario this is modeled for?

I can't come up with a reasonable situation where mobile networks are completely f*cked, yet my smartphone is still running medium- to long-term. Maybe I'm not creative enough.

(The only thing that comes close is a large-scale power outage, but then after a day or two my smartphone battery is dead too. Also, the same measures to revive the smartphone [solar backup, generators, etc.] can also be used to revive the mobile network...)

[Add.: what definitely makes sense is a _dedicated_ LoRa-based emergency network, which uses dedicated user agents with low power draw and long-term batteries. Just ditch the smartphone?]
