I work for a major telecommunications company in the landline division (we provide both landlines and cellular), and here are my own personal thoughts:
If you call 911 from your landline, your address, name, etc will automatically pop up on the 911 operator's computer screen. If you call 911 and can't speak, this could save your live. If your child or babysitter calls 911 and doesn't know (or gets too excited to remember) the address, this could save your life. The department where I work does the addressing for the 911 database for most of the counties in our state, so I know exactly how much meticulous work goes into making sure that this info is automatically available to the 911 operators. I'm proud to say that there are very, very few errors in that database (and when one is found it's corrected ASAP). When you call 911 using a cell phone, your location is triangulated to the nearest cell phone towers, and it's far from exact. I personally will never risk my well being, or that of my family, by dropping my landline and giving up the exact 911 locating.
A basic bare bones landline will run you around $20-$25 (including taxes, fees, etc) in most areas. Do you need caller ID, call waiting, voice mail, etc? Yes, they're very convenient, but I'd rather have a bare bones landline than no landline at all.
How long will your cell phone keep a charge in the event of a power outage? The unfortunate people in NJ learned this the hard way during Super Storm Sandy last fall. However, a copper phone line transmits its own power from the phone company central office. (Central offices have permanent backup generator power, which seldom fails. If it does fail, it's considered urgent and portable generators are brought in quickly.) As long as you have at least one corded phone in your house, your phone will likely work through a power outage of days or weeks. (On the flip side, if your phone is through your cable company, it does need electricity. There are battery backups, but they last for various amounts of time. I can't comment further as I don't know a whole lot more about cable technology.)
Do you have an alarm system that needs a landline? A Tivo? A fax machine? Do you have DSL internet service? DSL works on the upper frequencies of a traditional copper line. Dry loop DSL (DSL without having copper phone service) is available in some areas, but it's hardly any more money to just have a bare bones landline with DSL service.
I personally do NOT give out my cell phone number to anyone but family, a couple of very close friends, and my daughter's daycare. I don't want people calling my cell phone while I'm at work. I may work for a telecommunications company, but my boss is
not amused when our cell phones ring at work.
