I still have my landline. It is bundled with the internet and cable. If I got rid of it, I would only save $10 per month.
I have turned off the ringers so I can't hear the phone ringing with sales and political calls. Now I have the option of calling out from the landline in case something happens to my cellphone. If I wanted to, I could turn the ringer back on in case of an emergency.
The best part is that whenever a solicitor calls, they hear the tone from my fax machine. If they really wanted to sell me something they could fax it. That's never happened. I feel smug when I hear the fax machine click when I'm in my office. Another solicitor foiled again!
