GSM/Edge is planned obsolete.
Look at this map. Even 3G is ready for obsolescence.
If you're really looking for anything close to ready, you should look for Necunos which is rumored to use the same QMI-RIL that Replicant has been developing for years. Librem can't do code. Don't trust these fucks.
Privacy phone
S4 isn't supported.
S3 4G isn't available for valid reasons.
Dumbphone. Carry a laptop and only use your VPN when on untrusted wifi. There is NO private mobile OS and there never will be. Just get a flip phone for calling/texting and desperate web browsing in emergencies, never log into anything with it or connect it to your home network.
Let's discuss phones.
1) dumbphone
>dumb: probably can't leak anything to google/amazon/apple/etc.
Meme choice is librem5 nigger, you have a search engine. End of thread.
Stallman is right, just learn how to live without a phone. It's not that hard, worst case scenario, keep a dumb phone with a removable battery around.

The Librem 5 is the best bet right now to keep some semblance of control and privacy over your phone. "Dumb phones" can be tracked through cell towers, you lose a lot of functionality (web navigation, GPS, media consumption, better contact/calendar management, opening files, etcetera.) by using them AND they WILL contain nothing but proprietary and outdated firmware.
The biggest downside to the Librem 5 is the outdated specs, compared to modern smartphones, and the lack of app support it'll have. So it's like having a "dumb" phone with extra functionality.
As for Purism, they have delivered so far. The Librem 5 has been delayed several times and they have made several mistakes developing it (namely trying to adapt GNOME 3 for it instead of using already finished projects like Ubuntu Touch, KDE Mobile or maybe even FirefoxOS) but so far they have delivered all their other products.
if it runs normal gnu/linux then it will support lots actually useful things. only things it wont support is proprietary android botnet apps but people that buy this probably dont want to install snapchat or other botnets so it should be ok.
Exactly, i'm looking forward to install Gentoo on it and use it like i used to with my old Pocket PC.
Of course. It'll be able to run all of the GNU tools like mv, sed, gcc, etcetera. The Librem 5 is more like what we (or at least I) expected 15 years ago as "pocket computers."
The thing is that it won't have any mainstream appeal and it will not have any mainstream app like WhatsApp. Which may be a problem depending on what OP is expecting.
