Though I really like the idea of having some backup infrastructure already for those discussed simple cases like (top comment for example): car broke down and you.. .. forgot your mobile .. out of battery .. out of "credit" (in case of prepaid) .. cuz you got robbed .. cuz you got raped....(!) .. cuz you lost your fingertips and can't operate a touch display anymore.. .. possibilties are hopefully rare but endless but you're just in whatever emergency at 3 am and really need a to make a call!

But just for curiosity, whom/where you wanna call in 2022++ in case of overloaded networks like Sep. 11th in 2001. At least I didn't even "own" (actually set-up) my landline anymore.
