How does a Phone make Emergency-Calls without simcard and without internet?

In my country calling 112 connects me with the European Emergency Service, how is this possible when i have no simcard in the phone and no internet connection?
I'm running twrp with lineageos on a samsung device, so even on custom rom's this feature is working.

The benefits of being able to make an emergency call without simcard and networkconnection are obvious, but i do have question...
My phone is capable of sending signals to a far far away person via emergencycall, at the same time my phone is capable of reciving signals from this far far away person.
It all comes down to the one question, these outgoing and incomming signals.. are they only activated while i make the 112 call or maybe... always?

When i say these connections, we aren't just talking about a call now, no. I'm speaking about potential constant celltower geolocation tracking and who knows what not, camera, microphone, remote control.
That would be a privacy breach, does the government have the capabilites?
Any technical details with evidence?

I don't really have any "technical details", but this is what I found:

This has some helpful (and not helpful) info. Especially this one.

This looks like it has good info. (I'm still reading it)

I also stumbled upon this.

My own conclusion is that the Baseband processor (It is Wikipedia ) is probably the weakest point of most devices, and... It is possible for the government to do the kind of spying you mentioned all of the time, if they wanted.

After more research, I found this video: https://yewtu.be/watch?v=L8CYJdWjJ1E. I don't know anything about the guy, but there was plenty of info I found interesting. Simply put, like you said:

Most of the spying happens on the hardware level. So it doesn't matter what OS you put on it.

Interesting. I was watching another one of Rob's videos: link, and he said that Wi-Fi triangulation can be used all of the time, even with "no" Wi-Fi connection, in fact, it works even with airplane mode on. He says this is because Wi-Fi triangulation is a passive process, as it is done in receive mode only, and therefore airplane mode has no effect. There's Part 15 of the FCC rules for you:
This device complies with part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) this device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation.

I forgot to reply yesterday, that's some really interesting finds, you did way better than what i found
I'll try that expirement to, remove batter wait 10 min plug back in, check systemtime, ofc with no connections and airplainemode.
I'm still reading the other stuff, it's quiet a bit of text!
Ah that feels nuts, so even using twrp and lineage isn't stoping the glowies from remote spying, but really how could i think i can buy a phone in 2023 and not having a glowie backdoor in it, how stupd.
Probably they ain't using it, just the fact that they could if they wanted to is as if you have your door locked but it always remains a little bit open so when the burgler comes he could get in if he wanted to.

Oh ofcourse it's robbraxman, haven't seen all his old videos, i probably should.

Right so using custom recovery and rom minimizes the spying but that's about it.

Yeah i've seen that one, some scary sh!t. Only way to avoid wifi triangulation if i remember correctly is using an ethernetadapter to access the internet, i'm actually not sure about it.

That's what ChatGPT says:

By network are we talking about wifi or about celltowers or both? If it's wifi then i shouldn't be able to make an emergencycall when out of range, which would be easy to test.

I thought I was free from most of the spying with Lineage OS too. But of course the hardware plays a part. That Broadband chip still runs proprietary firmware and software on it. Speaking of, I got my Pinephone Pro but am waiting to use it until I finish a Raspberry Pi project I'm working on. Sounds like kill-switches and open-source is the way to go.

Look at this Wikipedia page: https://en.wikipedia.org/wiki/Covert_listening_device. Mainly the "Remotely activated mobile phone microphones" and "Automobile computer systems" sections. Sound legit, look at all those sources. This applies even more to Part 15 of the FCC Rules.

Yeah it make sense to buy a produt that doesn't just adverstise itself with privacy but does really stand by what it says.

Now that you mentioned automobile, so cars and motorbikes also fall in that cathegory, atleast they must have a constant gps tracker, how could to govt give the population vehicles without knowing where they drive that's a national security threat

According to this the Pinephone Pro has hardware kill switches for the following:

  • LTE (includes GPS),
  • Wi-Fi/Bluetooth,
  • Microphone,
  • Camera,
  • Headphone Jack (UART)
