I think the key difference between ham radio and cell phones is that in ham radio, you can always get an answer. (Or often, too many of them.) There's a lot of information and it can be overwhelming, like you have always been able to "bake" Pillsbury buns and now someone asks you to be a pastry chef.
So, you move at your own pace and pick what works for you.
As opposed to cell phones, where any time you have a technical question, the carrier will gladly answer with "We can give you a bargain on a new phone with a two year contract extension!" Ah, no, that's not very useful.
Some years ago I was deployed with a radio team to a shelter. Things were quiet all morning, and then we got a call over the radios "Please have all shelter managers try calling in to the EOC on their cell phones." A certain cell phone company had a sweetheart deal with the city, part of which was that they would sock every shelter kit with a couple of NTIA priority cell phones, charged, with spares, all set to go. And funny thing, when they tried to call in? They all got recordings that the number had been discontinued.
Once they got the carrier working on that, the EOC still sent out another round of orders by radio, to have every incoming shift place calls to make sure the cell phones were working, and to use the obsolete radio comms to report any that weren't.
In the years since then sure, cell phones have become way more robust. But they'll never be as FLEXIBLE as ham comms, and when any infrastructure collapses? Ham radio is like a mule, if you know how to work with one, it gets through. Sooner or later, faster or slower, but it doesn't really care about infrastructure problems.
A steno pad or notebook and some old fashioned NOTES can make it way easier, too.
