Because cell reception out here is spotty, we've got a landline. Had to use it as a fax line at least once last year.
Ditto here. I sometimes have to slowly wave the cell phone around up high to hopefully catch a stray reflection from a tower. There are a number of reflecting and absorbing objects around here which screw up line-of-sight E-M signals.
"System" at present:
Copper-wired voice phone line with DSL for my router. I also have a conventional answering machine which filters out a lot of no-voice calls and is therefore easy to clean up.
Also have that flip-phone for emergencies which is never on except rare circumstances. I probably have billions and billions of messages on the flip phone, but I never bother to look at them or clean them out since anyone I would
want to talk to knows I don't use it for incoming. (They know the number so they can recognize it if I call them on the flip phone.)
Thinking of revamping the system through Consumer Cellular, don't know yet if they can match my requirements. One problem I have is visual on a smart phone. It would seem I need to either get bifocals to handle the data side or constantly switch eyeglasses while dealing with it.
So presently:
Flip phone for outgong calls only, sometimes hard to get a connection from in the house.
Hard-wired phoneline for power failures and answering machine use, plus DSL for computer.
This may soon change when the daily challenges on other crap go down and I can take it off the back burner and deal with it.
