So, I just learned about this the very, very hard way.
After buying a second hand S10 and finding american ones can't be unlocked, traveling 4 hours to buy another one after much research, much annoyances to unlock it (samsung requires you to be online, which I didn't know) and testing multiple ROMs, I finally read this page more properly https://wiki.lineageos.org/devices/beyond1lte/ which says "known quirks: IMS". I thought it was just something like dolby sound.
What it means is that it doesn't suport VoLTE and most currently used phone systems. Samsung made their proprietary mess, unlike most other developers, which means it will probably never have an open source version.
And that applies to ALL modern samsung phones. I had samsung phone before with a custom OS, but didn't realize because VoLTE wasn't mandatory back then. Now it is here in Australia, and many countries. So if you ever plan to buy a samsung phone to degoogle it, know that it won't make phone calls. SMS and mobile data also doesn't work.
I don't know how I missed this. It should be talked more often given how popular samsung is. There should always be a warning "YOU WON'T BE ABLE TO MAKE PHONE CALLS IN THE FUTURE IF YOU CONTINUE".
S10 was the last decent phone ever made (for me). Not too big, SD card, headphone jack (one of the most important things for me), good camera, etc, etc... That's why I was so persistent to find one to degoogle.
So I'm stuck with my amazingly shitty pixel 5 (and other ones are even worse for me). And considering the possibility of a life without smartphones at all, since this is a losing battle. Mainstream doesn't care and evil companies have every incentive to kill freedom. It has been getting really bad and it will just get worse. But anyway... this post is not about this.
Be warned, if you care about freedom don't ever buy samsung again. Not because they are evil (they are), but because you won't be able to make phone calls on your "phone".
Don't use a smart phone for calls. That era is over. Get a basic, simple, trustworthy, and dependable flip phone with a hotspot feature and a separate mobile computation device.
Never send sms's or call on that flip phone though because you might as well be posting all of it on Facebook with how easily it can be read. Your carrier logs every text sent in plaintext.
Which phones with those features are even available? My first thought was the Nokia dumbphones, but it looks like they are exclusively compatible with T-Mobile, not AT&T or Verizon.
I would also like to know if anyone has any recommendations for US Verizon flip phones with hotspot built in.
Yeah but if you carry it around with the smart phone in your pocket, the phone you have just a data-connection on (or even if you don't and just use some WiFis), it's not gonna be hard for any sufficiently interested authorities to pair those two devices together as having the same user.
And granted, while it's not gps accuracy, having any wireless phone can be located (roughly) with triangulation.
But it's just like, how much privacy do you need/want, just pointing out things cause I have to keep distracting myself from having a bad day.
That's not the point here. The point is that there are (or soon will be) no iOS or Android devices that meet the most basic minimum requirements for personal computing, and for practical reasons abandoning the operating systems means abandoning the entire platforms. But we still need phone numbers to participate in society.
The point is you were trying to give tips how to avoid being surveilled, for some reason. I'm just reminding you of what not to do when you're doing that.
If you buy a dumb phone with a pre-paid connection, but lug it around in your pocket the same as your smarter phone, then it'll be trivial for the authorities to connect those two as having the same user.
You work in gov't?
I WISH, those guys get paid more.
Am looking into elections though.
Ha. 🙃
