When you all say you have a land line, do you mean a true, wired lanline, or a VOIP line?
We have one VOIP line that goes out when we lose electricity, and a real landline that ATT has warned us they'll probably stop supporting. We need the landline so that in a hurricane, when electricity is lost, our families can reach us.
ATT charges so much for a landline that, to keep costs down, we only have the line, no extras such as call waiting, or even a long distance option.
We have cell-phones that we keep in RFID blocking bags when not in use (for privacy as well as EMF concerns). I think I may have made 2 calls in 5 years. Gary uses his almost exclusively when he visits his mother in another state.
We decided to eschew cell phones when we saw the rudeness, self-absorbtion, and addiction they were encouraging.
I think they're a scourge on civilization, no matter their convenience.
