That's what's so great about LoRA. Decentralized txt msgs, ultra cheap radios people run at home or wherever. $10-35USD ON AMAZON. Least txts get through.

It won't get you from where you are to China though.
No but something like WSPR or FT8 would. Needs a license though.
FT8 has such a small payload that you couldn't fit an emoji, much less an average English sentence.
There's no authentication so anyone can pretend to be you. Traditional methods of verifying the sender (HMAC) would take so many hours to transmit that the physical propagation paths you're communicating through will probably collapse before you deliver the smallest verified message.
If you need to communicate information, FT-8 is not for you.

At a whole 3kbps and line of sight!
Local police already equipped with signal jammer cars. Usually only used in college entrance exam period. They also appeared in recent protest in Jiangyou city.
Can you recommend a guide? I’m interested in trying it out.
Look up Meshtastic. It’s kinda fun. Can chat with random people around you. But I don’t think it’s really that useful unless you have a really good spot like an antenna on your roof with no trees or buildings in the way.
It's not that finicky in practice. I live in a heavily wooded area and I can still see plenty of nodes, some pretty far away. Trees are actually somewhat helpful there because you can easily rig up a node up high by throwing a line over a branch.

That would be LoRa. LoRA is a different thing.
