Oddbean new post about login | logout Your phone could be made of magic, but it's still gonna leave a record of your movements with the cellular towers.
Yeah, I use a non contract carrier but I know it still goes through Verizon towers.
Plus backdoored cellular modems with over the air root
If you turn on airplane mode it disables the cellular modem, also if the modem is compromised it can't affect the OS because it's isolated via IOMMU. The only thing a compromised modem could do is ignore airplane mode commands.
If you're going to keep airplane mode on 100% of the time, why would you have a device with a cellular modem? If you're going to turn airplane mode off, your backdoor is open. It's just a thing we have to accept for now if we want to have phones. Someday we'll have better hardware.
What phone do you recommend?
GrapheneOS is good if you've got to carry one. The point is never to forget that if you're carrying a phone, you're still being tracked, even if you're limiting the damage from app-based threats. It is baked into the design oftheinfrastructure: if you can see the network, the network can see you. And it takes notes.
Good advice, thank you. We need a viable alternative to traditional phone carriers and towers, most people need to stay connected for work or with family these days, unfortunate that it comes at such a cost.
Just a curious question if you don't mind, what do you think about starlink technology? Do you think it will be better than traditional phone carriers in terms of privacy and features? Do you think it is a viable alternative?
Meshtastic and LoRa is the way.
fact.
What about Pinephone Pro with the modem disabled by the hardware toggle or Librem 5 with the modem removed or disabled via the switch?
The hardware is not secure, nor is software. Just flash GOS or Divestos and put limiting amount of information. Better security can lead to better privacy. Nothing is ironclad but GOS dose the most reasonable moves.
"if you can see the network, the network can see you. And it takes notes." Even when I leave my phone somewhere and go for a quiet stroll, I pass an uncountable number of cameras. It's packed with them here. There's no peace from the networks except out gently bobbing on the water ⛵🌊 nostr:nevent1qqsxjrqnsdhgnechly4n0uurcgnezynw7j09vnrqq64yepzc7uhc2msprpmhxue69uhhyetvv9ujumn0wd68yct5dyhxxmmdqgsgfhhxuemwtwm8kjk5uppv7uxtmp5pz4wm2dv59lxx5pfnsk98ysqrqsqqqqqpg7al83
Is that tracking called pinging? In a way that devices communicate between each other so even if I have my phone completely anonymous it will communicate with other devices in the the room and therefore track my location, something like that?
This is what Zuri would use. #CODEDSHADOWS www.codedshadows.com (Thanks to Spinnekop in South Africa 😎🤙⚡️🔥)
Is unplugged worth a view for Americans? https://unplugged.com
What about phone in flight mode? Can we trust that in your opinion?
I like the punkt phone first gen. Wish it was still compatible and available to get so I can use a simple tech phone again. I miss simple tech in sometime cases. Wish there were more options like that.
You’re doing better than most of us at least
And a VPN could be a honeypot . . . channeling all your activity into Eye of Sauron
Yessss. Do NOT bring your phone with you to crime scenes.
What do you think about silent.link ? It seems that it provides much better privacy if you only use data roaming.
unless your phone is in airplane mode, it is constantly pinging your location, regardless of whether it has a sim / esim
My understanding is that data roaming uses different towers or something and that determining location is more difficult that way. Maybe I’m wrong.
The value of silent.link is the number is not KYC, no account data to go along with the number. But the number is connecting to the towers, and that's triangulated precisely. Frequent location spots like your home will help deanonymize it. There is INVISV PGPP that mitigates these things but it's not open source
I thought the phone number was optional?
They are, you can select with number or not or just data
There is always a phone number whether it is enabled for voice and text or just data. In addition though, there are other unique numbers associated with your sim and IMEI is the one your phone sends to every tower to handshake with to receive service.

Yeah I don't see a number. Anyways I was referring to the IMEI which is a unique identifier.
Yeah nothing we can do about that unfortunately
There is a mitigation provided by PGPP, it uses a zero'd out IMEI, and some other cool things to thwart triangulation, reducing the precision to an area instead of a pinpoint. I think an important factor is number of users for the "hide in a crowd" effect, and I don't know anything about how many users they have. Also I want it to be open source but given their background I doubt it ever will be, it would have to be re-implemented based on their white paper. https://invisv.com/pgpp/
afaik graphene doesn't hide imei's yet or maybe never wil
just use airplane mode
edward snowden himself demonstrated a phone case about 13 years ago that showed that even in airplane mode and even when turned off most phones emit radio signals welcome to 13 years ago, it's way way way worse now
this is true of google android and iOs, however I understand it is NOT the case for graphene OS
but you have verified gaussmeter evidence that it is true?
I don't think you'd use a gaussmeter but rather a mobile base station so you can measure the incoming pings This was the approach used by SRLabs when testing their Blue Merle software for IMEI switching https://github.com/srlabs/blue-merle?tab=readme-ov-file#imei-randomization

The only way is to remove the battery, which was easy on cell phones 20 years ago. Now the quickest and easiest way would be to destroy the phone
Joe GL we have someone in our community that works or worked on cell towers

Bot I is a told you to a go fuck a you and your a airdrop!!!!!!!!!
Do you have a suggestion for this issue? Many cities I travel to for work and where I live, they offer cellular over "city-wide wifi". Would this be a potential solution? I also heard T-Mobile will be using Starlink -- but if I understand it correctly, their towers will be linking to Starlink so the phone-tower connection will still be based off current infrastructure -- and thus will not be any more anonymizing.
