I haven’t had a landline since 2007. Google and Apple have rolled out a service that will give your location if you call 911. If you set up your emergency contacts it will also notify them that your phone has requested emergency assistance and share your location for a given time. See first link below. Later versions of the Apple Watch will call 911 if your heart stops for a certain time or it senses a hard impact like a fall or car accident. It asks you first, if no response it calls for you. Pros and Cons to that, but we don’t want to bogart the original post. Keep your landline, mine only received spam calls too. Just know there is technology out there that will still you let you make an emergency call on a smart device.
