Does anyone else get many calls that can’t get through? I just had somebody trying to ring and couldn’t get through, but they were able to text/SMS me. Phone was probably on power save at this point, but can’t be sure.
Is there some way to check the modem firmware version? I saw there was a thread about updating it helping, but my Librem 5 wasn’t one of the early ones, so was hoping I’d not be affected.
No, but I usually keep my Librem 5 USA in Lockdown Mode.
Yes, execute sudo apt install bm818-tools, then open the app.
… as in “Suspend?” If so, then that’s still considered “experimental.” Does disabling Suspend have an effect on the calls problem?
I tried that, and get issues. It says it can’t install, and to try with --fix-broken. I ran that, and that fails because /boot is nearly full.
To be fair, the phone has been warning me about that every time I powered on and I was just hoping it would go away.
I would have to test that I suppose.
Recently I have been getting those symptoms on Crimson too, so I interpret it as a call to action to reflash with a new image.
If are receiving warnings that /boot is nearly full, then that stops apt from installing updates and maybe even packages.
You can follow this guide to see if it helps with /boot, and then try installing bm818-tools again.
Hmm, tried to follow that, but something is wrong. I can’t clear off the oldest kernel.

You might want to run ‘apt --fix-broken install’ to correct these.
The following packages have unmet dependencies:
linux-image-librem5 : Depends: linux-image-6.5.0-1-librem5 (>= 6.5.13pureos1~byz1) but it is not going to be installed
E: Unmet dependencies. Try ‘apt --fix-broken install’ with no packages (or specify a solution).
Maybe you are stuck in a dependency loop that apt really does not like.
Try out the instructions from this link under the heading “Errors when /boot is full”
I tried the steps in that last post, and seemingly that cleared /boot enough to install all the pending updates, which is great.
However, that bm818 tool just says “failed to get firmware version” for some reason after all that 
I received that same error. For me, it was because of lack of permissions. Specifically, if you are running the tool as user purism then purism will need to be a member of the dialout group.
I thought the most recent version of bm818-tools was supposed to do that as part of the installation now?
Just in case, @biggaz can follow these instructions to create dialout group and add purismuser to it: https://www.howtogeek.com/50787/add-a-user-to-a-group-or-second-group-on-linux/
Yes, but I didn’t run the install as user purism, therefore the installation added the “wrong” user to the dialout group. So I had to add it manually.
There are other possibilities, such as: the user installed that tool before the install was semi-fixed.
So the starting point for investigation is output from
whoami
groups
Am I up to date?
What modem variant? (-A1, -E1, -T1)
You might have to refer your question to Purism Support (as there is no public procedure for updating modem firmware anyway).
For the time being we only offer BroadMobi BM818 modem. Three variants are available, BM818-A1 (Americas), BM818-E1 (Europe), BM818-T1 (Asia, Australia, New Zealand).
Being in the UK I suppose that will be the E1 modem then.
Yes, you are up to date.
