1. Second cellphone.
2. You don’t need a SIM card to call emergency numbers.

2nd is also important in that your phone is always connected (unless in airplane mode) to some cellular network, and can still be tracked the same way (unique IMEI).

Imagine a standard zombie apocalypse movie. Someone comes up with a vaccine, but instead of the ending showing helicopters and planes transporting them, happy people leaving ships, people cheering in camps and getting mass-vaccinated, a new war just starts. Armed antivaxxers destroying labs, produced vaccines and vaccination centers, and the entire humanity just fucking dies.

THE END

From: https://support.saily.com/hc/en-us/articles/15751399206172-How-do-I-install-the-Saily-eSIM-on-my-device#Android-Manual

It seems you could install it on different device then. There’s also “share eSIM to other person”, which likely too just shows a QR code.

I don’t know about Saily, but I doubt they would want ID. At least for data-only SIMs, if they do offer ones with phone number.

I did a similar thing with a different eSIM provider when I was concerned about privacy, though eventually I did put it on my phone.

I don’t know what else to use on Linux to get disposable Android containers.

Anyway, while it is not related to privacy, they also seem quite expensive. At least for Europe. I don’t know where you’re going. I’ve used BNESIM, which funnily is cheaper than local SIMs for small data amounts (like 1 or 3GB), especially with SIMs without expiration. That can be used without app for sure, but I’ve had to use non-blocking DNS.

Anyway, whatever you choose, use virtual payment cards. Something like privacy.com. There’s a ton of eSIM providers and I am sure they’re not all super safe and legit. My bank provides those thankfully.

How does DD-WRT fare? I’ve been using that, but I only have old routers. I mean, old. But I only have mobile data, so they’re mostly for playing around. Except for the one which supports Wireguard in DD-WRT. That’s very useful as a client. Unfortunately, it’s also the least stable one, rebooting every few minutes and eventually ending up in a bootloop after 1 to 2 hours.

I’ve got I think 8 routers now, 6 of them have Wi-Fi, 1 has 802.11n (the unstable one), the rest peaks with 802.11g.

Only from the Lemmy image view, but the original is JPEG and you can download it too.

It could also be delivered to a pick-up box in which case it’s at worst illegal or at least against ToS. “Billing address” just sounds like something potentially serious.

I think VLC can also open them on Android.

Actually, 8.5GB. Movies are typically on dual layer discs.

I used K3b for that. It can copy to image and even ignore errors if necessary, though I didn’t yet have to try that. It’s 8.5GB per disc, so get some 2TB HDD for that.

Well, perhaps not Monero, and perhaps not a loaf of bread either, but also not far from that. One large e-shop in Slovakia I use (Alza) supports crypto payments via Confirmo (BTC, ETH, USDT, USDC, SOL, POL, LTC, TRX). They sell mostly electronics, but also some food items.

Now, since you’ve mentioned bread:

But I haven’t yet tried crypto.

There’s also a RISC-V laptop - DC ROMA

But it’s still mostly experimental, rather than for regular usage.

Is there something that has to be done first (like Windows generalization)?

They are newbies, for now.

I have had a Linux Mint USB (installed, not live) with me since middle school. Not the same one, of course, that was USB 2.0.
SanDisk CruzerBlade seems to work pretty well. On the other hand, a Panasonic flash drive I have is absolute shit for random access. Booting up install from it will take ages and then it will freeze up all the time.

External SSD would be best, but it’s not worth it for occasional use.

It could rather be more accurate in a dense area thanks to more cell towers. And it seems mmWave 5G can get below 1 meter in accuracy.

A cheap dumbphone could come in handy at almost any age* (calls, short SMS, especially in emergency situations). Though there is a possibility they wouldn’t want to be seen with that. Kids will bully each other for whatever isn’t a norm.
Anyway, preferably a simpler one. I used to spend hours each day on Java games. Really, the only thing that stopped me was headaches.

* Almost any - you don’t want a 3 year old calling 911 for fun

Just like 3 weeks ago I started using Tailscale. I’d highly recommend trying that.

It does some uuuuh… magic to establish direct connections on most networks. You can verify whether you’re using direct connection or relay using tailscale status on Linux.

It uses Wireguard under the hood. There’s also Tailnet lock feature (still in beta) in case you don’t trust Tailscale to not maliciously add devices to your Tailnet.

This would give you lower latency than the VPS solution. I use it with CG-NAT on both sides. I also started using it for LAN since it establishes direct connection over LAN too, and seamlessly switches between networks so I can disconnect from LAN and keep current connections going over WAN or vice versa.

But I’ve just tried now, and it won’t work even on LAN without internet access. Still better than a VPS solution in some way.

But you may also try looking into headscale which is basically a lightweight self-hosted private Tailscale control server, but I haven’t tried anything with that.

Not sure if you’ll find something that cheap, but RackNerd has some pretty cheap offers sometimes. Thing is, they don’t seem to expire, so there’s this: https://racknerdtracker.com/?sort=price

But I haven’t tried them yet.
Also keep in mind the monthly bandwidth limits.
You get what you pay for, and $10/year is basically nothing.

Oh, and you may be responsible for random people’s traffic depending on the provider. I think I’ve read in ToS of some VPS provider that you have to notify them about running a public service for this reason.

I sometimes get this with Mullvad in official YouTube app as well.

Or streamed directly to your device, only relayed through Tesla’s servers if necessary. This wouldn’t need much bandwidth as most connections could be directly peer-to-peer.

You know, I am just thinking of something like Tailscale or WebRTC. Though this would need a 24/7 connected app, so probably not the best solution.
Though if it were used just for the video streams that would likely help a lot too.

Or maybe release some server software that you could self-host and set up the custom one in the car. That would also have the advantage of being independent and future-proof.

Would probably be OK to include in the car costs. You know, like smartphone updates. You don’t pay a monthly fee for those either.

Edit: As for car’s connectivity, it could just have a modem with user-replaceable SIM card and/or eSIM. If the current ones can’t do that, add drivers for some USB modems and USB Ethernet adapters.

DivestOS is discontinued, and together with it Mull. It won’t receive further updates including security updates. Based on F-Droid there is a known vulnerability. It is recommended to cease usage of Mull ASAP.
