Unfortunately, the mobile data connectivity sometimes gets lost. I experience this as well. This is a known bug:

https://source.puri.sm/Librem5/OS-issues/-/issues/328

This issue is not related to the mobile provider as far as I know.

With Crimson (the beta of the next PureOS release) I have the impression the bug happens less. But this is difficult to prove. See: https://forums.puri.sm/t/crimson-experience/22228/304?u=janvlug

@eve VoLTE is working on #Librem5 with #PureOS and #postmarketOS, so I'd expect newer devices to work as well.

Btw, a new global modem upgrade option for the L5 is also apparently coming this year.

@archivescribe @DaveMasonDotMe There's the #FLX1s from @furilabs

Also, upcoming projects from @mechasystems, @dawndrums and @Liberux

Of course, there's the #LibertyPhone / #Librem5 from @purism for true #gnuLinux... which I heard is receiving a new modem upgrade this year. That's what I'm currently daily driving with #postmarketOS.

Het default operating van de #Librem5 is #PureOS, dat @phosh gebruikt. Phosh heeft roots bij Purism.

@verdre AFAIK distros like #Fedora currently tend to default to something like 50% of ram for the default zram size, while e.g. #postmarketos recently switched to 150%, see https://gitlab.postmarketos.org/postmarketOS/pmaports/-/merge_requests/7754, #pureos to 200% (https://source.puri.sm/Librem5/librem5-base/-/merge_requests/381) and Android and ChromeOS both overcommit as well.

I saw this helping a lot when compiling stuff (like libcamera) on my Pixel3a, which previously aborted because of OOM - that vanished completely.

So this might be a low hanging fruit for various distros.
