Relying on cell connectivity

A lot of places in town just don't get decent cell reception and we're lucky to stay in an area where all the networks work really well. The way we rely on our cell phones these days, it would be hard to not have them working at all times. We did get a land line, but barely use it and just cannot remember the number. Who remembers any kind of telephone numbers these days, anyway? Besides a few telephone numbers of my immediate family, I don't know any numbers at all and rely on the address book on the cell phone. Interestingly, I still remember my grandparents old telephone number from when I was a kid!
