This sounds like us too. Our choices are satellite, hot spot or DSL. The DSL turns out to be our best choice using the phone line.
We did away with the land line phone about 12 years ago. My wife put a cell phone in my hand and said use it! The leash!
When we moved into this housing development 10+ years ago, the only line available to use was DSL phone and internet at 25Mbps. My wife has a sister that lives in Canada and calls to Canada were extra–something like 200 or 250 minutes for about $10/month and $$ for each extra minute after. Blowing through the 200 or 250 minutes a month was a piece of cake for my wife and her sister!
Our cell carrier was either AT&T or Verizon, both of which charge extra for calls to Canada, and their reception was bad at the house. So, I switched the DSL phone to VoIP and had unlimited calls to Canada. The VoIP was through a base station/answer machine with cordless phones in every room. We’ve since switched our cell carrier to T-Mobile with unlimited everything, including Canada, but we prefer using the conveniently located cordless phones. And, I’ve never had a cell phone conversation, no matter where I’m located, that’s as clear as a landline or VoIP call. So, I have no intention of getting rid of the VoIP line or phones.
Bingo. And guess what - your landline phone doesn’t need to be charged every night, nor does it run the risk of being dead in the morning because someone forget to recharge it.
We are in an area prone to hurricanes. Usually the land lines are back up and running before cell towers. Reception on the land line is better here and multiple people can pick up on land line extensions that are better than trying to listen in on a cell speaker.
I still have a landline since I use Tracfone for my cell service. For my usage pattern, it is far cheaper than most if not all unlimited talk services. But the landline has zero operating cost since I use obi with google voice.

Tonight t-mobile has gone down. No phone calls, no texting. Thank God for my landline.
My phone can use either cell towers or WiFi, but the default when home is voice over WiFi. I’ve never had it happen that both WiFi and cell towers go out at the same time. I’m in the Atlanta area, so we don’t have hurricanes. I suppose a tornado could take out both cell towers and WiFi. But if it did that, the phone wires would likely be down too. If everything were down I could always drive to a live cell tower if I really needed a connection. Try that with a landline. 
I think I have some extensions in a box somewhere if someone wants to give it a go. 
My comment was mean as humor, considering the timing. It didn’t really require a response. But Ok.
Now I see the humor! I see in my newsfeed this morning that T-Mobile phone service was down for up to 12 hours starting at noon yesterday in some areas of the country. I wasn’t affected here in an Atlanta suburb. Anyway, your point taken. I was trying for humor too, offering to take a landline phone extension out of the house to a cell tower and making it work. Oh well, a lot of humor, and meaning gets lost in message texts. Peace and stay safe out there.
Voila
We had a single point of failure last year. Our small town is connected via a single fiber cable to the internet. All phone calls are routed via the internet nowadays. Even those called by mobile phone. A construction site in our town’s centre scratched this single fiber. It took 2 hours until we were online again by landline and cell phone.
Yes. Texting falls short when it comes to humor. You stay safe down there in Atlanta. It doesn’t seem to take much these days to set people off
While I Live in a decent sized city. I’m in a valley with zero cellular service. I’m lucky if I get 1 bar. So having a landline is essential for us.
Plus, only friends and family have my cell phone number. 90% of the spam calls go to the landline. 
@Dani we had the same issue maybe 10 years ago in the town I lived in in Southern California out in the high desert. A road construction crew accidentally cut the one fiber connection into town. All the internet, all the landline and cell phones, all the ATMs, all the credit card swipers, everything went down. Took over 24 hours to repair. It was really weird. And that was in a town with one of the US’ major weapons testing facilities. (Same location as the July 4/5 earthquakes in 2019…that’s when we knew for sure we were high tailing it out of there.)
Some keep it for their Fax machines.
Good point. Forgot about that.
Fax’s can be sent to an email address thats how my work did.
I believe that might be a “pay for” service…
No it’ just takes the right software and no I don’t know which one you would need as I am retired now and we don’t have any need to receive fax.
I do have a monthly report to send in. After I fill out the form I print it out sign it since it requires a accual signature take a picture and email it to the office which meets their requirments.
My wife used to be able to bike to work and kept getting flats (broken glass). She doesn’t change bike tires, so I’d get called… if she could find someone willing to let her use their phone. So she got a mobile phone at that point.
A couple years later, we needed to keep two land lines (locations A and B, different cities). Ditching two land lines and getting me a mobile phone was cheaper, even 20 years ago.
It was somewhat awkward in the early days of mobile phones (I have memories of both of us leaning in to hear the speaker phone on her mobile phone). Now, we can do three-way calls for no additional cost, and of course some family members prefer texting, some prefer video calls, etc. The mobile phone can do all that these days, allowing me to keep in touch with more people.
