Cell service is not available everywhere. Reception can be spotty in a lot of places.
I understand that, to which I support keeping landline going for those places. I’m not interested in ending landline services where cell phone services are spotty. However, in some places, we are metaphorically running a trainline for a single person just because they don’t want to buy a car.
It should be a gradual thing, to where formally unserviceable counties are now being serviced.
