LoRa is pretty neat but as Ren says it requires significant tech know-how. Unless you have a bunch of tech savvy friends or want to have a number of LoRa devices yourself its use will be sharply limited.

There are ham radio HTs with features that might be more useful — APRS reporting can work for some miles without a repeater, and far longer with one. This requires licensing and expensive equipment.

For worldwide capability without a license exam, something like a SPOT could be a viable option.
