The tech has already been proven—carriers just need to be mandated to add it because there's no business reason to do so.
People say that but in the decades since it was thought up mesh networks have never actually managed to work, not at any scale. Routing efficiently is extremely complex especially when all the nodes keep moving around. I concede it may be better than nothing in an emergency but I strongly suspect it's just not very useful in general, which is probably why carriers haven't mandated it. After all if it worked you wouldn't need carriers at all, yet here they are...
In situations without access to a fat, centralized link or situations where resilience is more important than bandwidth or latency, mesh networks are a great choice. Emergencies are such situations but remote areas or low power needs are other situations suited for mesh networks.

It'd work fine in more dense areas. Probably not the higher band 5G stuff, but lower bands and 4G. There's no carrier incentive to do this, that's why OP said "mandated".
Especially the infrastructure-less TETRA DMO Direct Mode Operation for ad-hoc communications with the trunking infrastructure down, out of range or over capacity.
And everybody in the Public Safety radio space seems to always laugh when LTE Direct is brought up. Apparently poorly specified and adopted by no vendors.

It’s not much but it’s a network nexus with an insane number of backbone links for redundancy.

Being someone that usually lives in the low end, I have never had a phone without FM.
Waterproof phone = no headphone jack = no FM radio. There are some exceptions, but it's more often true than not.

EDIT: It was a Nokia 6086, and the radio was an FM receiver.
But surprised that there are no 3.5MHz/7MHz/14MHz band frequencies in use for regional communications. Or they have not been declared yet for emcom use like with Nepal and Puerto Rico.
28.540 has the benefit that you can push it rather far on a modest antenna -at any hour - much like CB, and with digital modes you don't need to be able to "hear" it to copy and send copyable text. Most regional nets will be on VHF, UHF, or NVIS HF (the 3.5, 7, etc) depending on the conditions and time of day.

It's always nice to see this technology (and the community) lean in to support disasters like this.
Note that all portable multiband radios will have an antenna optimized for 87-108MHz. If you want to receive shortwave better you'll need to add a couple dozen feet of wire to the antenna: https://en.wikipedia.org/wiki/Shortwave_broadband_antenna
For people on the ground it was Telegram groups and channels. "TG" is huge in Russia, Ukraine and Belarus.
Is it 28540KH?
From this site in Washington there's nothing - http://na5b.com:8901/
A site in France seemed to have nothing.
How close does it have to be?
[edit] I will say WebSDR is fucking cool. Closest I can see is http://94.137.189.166:8901/ Tbilisi - Georgia 500 miles away but doesn't have anything, unless I'm using this wrong.
here's a complete session to check my winlink mail: https://www.youtube.com/watch?v=DA6JRB560eM the actual transmission starts about a minute in, the first minute is my station waiting its turn
Fortunately, the 10m band these days has a reach of up to 11000km due to the solar activity. You are quite right that during LOS conditions it’s limited to the elevation of the antenna.
Its relatively small antenna needed (5m dipole) and can be used to access some distances, just not ones that might be in the same country as origin because of the skip dead zone from the ionospheric refraction angle. Which depending how it might be used, could be useful.
The general rule of thumb is to check the MUF Rating at the time of day collected from ionosondes such as that on https://prop.kc2g.com/

You just... stop caring. The only two good reasons to pay attention to news are if it affects you in some way, or if you can do anything about it. The vast majority of news is in neither group.
That's the first pass. From there, you adjust your definition of "affects you". I'm in the US, for example, and our government does plenty of bad things I do not approve of. But most of them, even the ones that ostensibly should affect me, don't actually noticeably change anything in my life. After a while, it all blurs into "my team scored a point" or "the other team scored a point".
Is this privileged? Of course. But it's also a requirement for my mental health. Paying attention to it wouldn't even improve anything for the people who are suffering, so there's not even any sort of utilitarian tradeoff. It would just be making my life worse for no reason, so I don't.
Idk one thing I do not ever do is open a website like CNN or NYT and read the front page. Please don't misunderstand that statement of fact as a judgement, but you asked about my media habits so I am sharing that. I will hear about major news events, as this very post makes clear. It seems I am hearing about this major earthquake in Turkey 14 hours or so after it happened... which seems fine. There is nothing I can do.
I tend to get news from youtube sources (not major outlets though) and these creators take a day or two to produce their videos. Sometimes I listen to Democracy Now or the KPFA evening news (available online), but I do not regularly consume that kind of thing. I am doing as much as I can to help the world with my little nonprofit thing. I learn about things like the police killing in Memphis police killing, the situation with the police training center outside of Georgia, and various foolish things politicians do. But I don't have much appetite for the firehose of details that come out of major news outlets.
I personally take a great interest in the challenges my local community faces because I can be directly and verifiably helpful.
It's not that I don't care. (I do.) I just read everything at a digest at the end of the day. Most news doesn't require a real-time response. Trying to stay on top of everything happening, as it happens 24x7, just leads to emotional exhaustion.
If it's not something I have direct control over, I don't need a real-time feed of it. The news will still be there to read in the evening when I get home.
Grab the Sunday paper if you want to be periodically checked in. I think I'd be happier if I did this. I don't need to read the nyt opinion section every day, or what lie some congressman from New York just told.
I need to fold my clothes and schedule my vacation and research for work.
I read the newspaper once a day in the morning, HN a couple of times during the day, that's it.
No other news or social media at all. I get a lot done. I recognize this lifestyle isn't for everyone.
The only exception I can think of is Japan. It seems everyone is aware of Japan earthquakes/Tsunamis.
It is possible i am misremembering, but it could have been a fore-shock, as well.
Note: i don't watch fediverse or any social network enough to have seen any other reporting or whatever on this. My phone spammed me about it, the first such notification i've received this year, and i live in a Gulf state in the US.
I generally just don't care enough about what happens in the world anymore, though this particular quake is really terrible of course. But there's nothing I can do about it.
Just once a day or so I might check the local newspaper website, for things that might affect me. Which is where I heard about it because something this big will make the front page even there.
But generally I don't miss the world news at all, I don't feel FOMO or less informed. I'm not a boring person either IMO, I just like being active in tech and the creative (maker) community, with things I can actually influence. I'm very interested in people I meet. It's more about taking control of information.
I do the same with instant messaging. I can be quite active but only on my terms. All my group chats are muted, and all but the most important people too. I'll see your messages eventually but when it suits me. If it was urgent you'd have called anyway.
It's good to know about this band assignment though as I'm also a HAM operator. But I don't use the 10m band that this frequency is on anyway.
Staying informed is good, but there are relatively small number of things that need a reaction in real-time. Eventual consistency is sufficient, and frees cognitive cycles for things I have immediate influence over.
