To remember: LoRa only permits small text messages. Don't even think about images, voice nor binary files (I mean it).
Another option is APRS using satellite connections through a cheap chinese walkie-talkie (Quangsheng UV-K5) for 20 euros to send text messages.
APRS is a bit better, because it requires ham licences and (usually) a bit more expensive equipment, but with "SmartBeaconing" and just a few hams, you get collisions (multiple people transmitting at the same time, effectively jamming eachother).
Reddit is usually full of preppers and other idiots buying these cheap chinese radios, usually without any knowledge and licences (that are needed to use them), and in turn they know nothing about actual use of those devices.... simplex range in urban environment is measured in hundreds of meters or maybe one or two large buildings between radioss, and repeaters will be in use by actual emergency servics and not really usable for any kind of "private use".
tldr: get a few books, a pack of cards, wait it out, not so long ago being unreachable away from home was the norm, and we managed.
Portugal was for 24 hours without electricity. LoRa networks were jammed and non-operational because the bandwidth is limited. APRS kept working.
It is far better to have a walkie-talkie that you can use as PMR on the 446 range and use for satellite text messages than an expensive toy that very few use.
And as you also know: You do NOT require a radio license when operating under emergency situations, which is the context on this case.
In portugal? Yes, you need one. Probably in every other EU country too
In USA too.
I have no idea where people got the myth of not needing a licence in emergencies, probably due to not reading the actual rules.
Also, you cannot use the same device for PMR and ham radio bands, the PMR device needs to be certified for PMR use, that means that it can only transmit on pmr frequencies and nowhere else. Other devices (eg. ham radio) cannot be used on PMR frequencies.
It's not FUD, it's regulation which exists for good reason, because in cases of actual emergencies, trained ham operators can assist actual emergency services with communication, and that's impossible if every idiot with a baofeng jams the channels.
In Portugal you are legally permitted to use channel 9 (27.065 MHz) in addition to the PMR channels. The hard line has always been on public safety bands. From a long time cooperation with the authorities (especially around the Azores) there was always an informal permission for that kind of usage across boats and islands because communication is difficult there.
Last but not least: taking the radio license exam is NOT a drama. Anyone can apply and get the radio license when they are serious into this topic.
Channel 9 is a CB channel, and neither quanshengs nor baofengs work on those frequencies at all, but you need a certified/type-accepted CB radio to use on that frequency.
Same with PMR, you need a PMR radio to use on pmr frequencies.
It's not FUD, it's just hardware limits and regulation.
Yes, 12yo kids can get an amateur radio licence, it's easy, but you still need a licence to transmit on ham bands, and you still cannot legally use a baofeng (except the few pmr models) or a quansheng on PMR frequencies, those radios don't transmit on cb freqencies at all, and there are no legal "you don't need a licence in an emergency" exceptions.
You should worry about knowing the procedures, the channels, how to engage in communication with the hardware available to you.
Now the best way is to get licenced and drive (=use a radio) in "normal" cirumstances to get experienced before an emergency. Somehow 12yo kids manage to get licenced, but preppers can't.
