Satellite phones are extremely easy to determine point of origin, give or take 20m. That's enough to dispatch police or worse, launch an airstrike.
That's exactly how Dzhokhar Dudayev was killed: using two laser guided missiles while he spoke on sat phone. The signal was interceped by a Russian reconaissance aircraft.
I just tried the app via the US App Store and it requires you to verify through SMS before use. This means that it’s neither anonymous nor fit for use in a disaster zone. Good example of software that would be better if open source.

I had the same experience and was disappointed. But a good mesh app is inherently difficult to monetize! Combining mesh over some/several form(s) of 802.11, Signal protocol public key distribution "locally" via QR code, and Delay-Tolerant Networking (Cerf et al. 2007) would be the holy grail (and would have no reliance on SMS or phone number) and also could not be monetized. Which is a damn shame, because it's eminen…
Does everything need to be monetized?

This kind of device matching can be done across any of the carriers or their MVNOs, all of them give up the data when asked by a government entity. Many tower locations will even be identical across carriers, making the matching even easier. Also this correlation could be done with stingray towers without bringing the cell carriers into the loop.
With the higher clustered protestors the tower linking won't be as identifiable as you might think.
I don't think gp here is in china, but rather just offering their procedure for acquiring a burner phone.

This tactic has been used a number of times that I'm aware of, in Eastern Europe, South America and the Middle East.
A drone will act as a receiver/relay for the phone signal, and then triangulate the phone's location.
I find the idea interesting, but is there some kind of open-source alternative that would be available on F-Droid? This would be extremely useful since you can share your F-Droid archive over bluetooth, and that would also allow the app to be distributed the same way. One less way for the authorities to block the app from being acquired.

Seems to be available on F-Droid, but unfortunately is not cross-platform.

This burner phone and your "real" phone are going to be easy to correlate retroactively based on the towers they are both hitting
I'm not the only one using my tower I am sure about that. I am not that special.
No closed source mesh networking can be secure. However good user experience it has. They are no different than using WhatsApp. Indeed in that respect at least Signal is better. I am not sure why protestors did not adopt the open source serval mesh project apk and ios app. [1] In Hong Kong given the density of building it's bit hard to have a line of sight, so it will still be hard to build a local network. But it's…
