Do these work with European bands? Is it worth shipping to Europe?
It probably doesn't matter which specific band.
I honestly don't know
I did not understand any of that...
This is the easiest explanation I could come up with:
Your phone (or other cellular devices) constantly broadcasts a few identifiers. The IMEI, which is tied directly to the cellular hardware in your device, and the IMSI, which is tied to your SIM card. Law enforcement uses so called cell-site simulators, which basically pretend to be cellular antennas, while actually just grabbing IMEIs and IMSIs from every device in the area. This is often used during protests, in order to identify those who attend them.
Rayhunter is a piece of software that detects the presence of cell-site simulators, making attendants of protests aware of the hidden danger.
This is especially important, now that the US basically transformed into an authoritarian state. We've already seen how Trump strategically uses law enforcement to crack down on protests, such as the BLM movement in 2020. (https://www.youtube.com/watch?v=K_a63r5Km9I) Being aware of law enforcement/intelligence operations that try to identify and track down protest attendants is more important than ever.
Short version is it's a man-in-the-middle detector to see if you're being spied on, using a cheap off the shelf cellular device.

It needed Xposed framework and worked only on some devices, which are not available anymore.
It probably needs some permissions that aren't available in newer Android versions anymore
Is it necessary to get a cell plan to run the hotspot? If its just a matter of buying the $20 and loading EFF's software, I'm definitely onboard!
Is it necessary to get a cell plan to run the hotspot?
As far as I'm aware: no. Cell-site simulators could theoretically only target devices that connect with a valid IMSI, but I kinda doubt that they are doing that. But you could get a cheap prepaid SIM, instead of an actual cell plan.
I know for phones even an inactive sim works to talk to the towers enough for 911 to work. Might be the same.
Doing my part!
Just got mine and getting this error. Would appreciate any support you nerds can give me because I don't have a Github account:
Using adb at ./platform-tools/adb
Force a switch into the debug mode to enable ADB
/Applications/release/install-common.sh: line 20: ./serial-macos-latest/serial: Bad CPU type in executable
Edit: Installed via Linux, here's what the UI looks like
There's now a green line going across the top of the display and apparently if it detects any problems the line will turn red. Still no idea how I get that info back to the EFF though.
Whoever designs their logos definitely needs a raise IMO.
I'd buy all the stickers if it didn't cost twice their value just to ship them to me.
I hadn't noticed this until you pointed it out, but yeah, their logos are fire
