Strange. I have to enabled it after every boot. Sometimes I have to reboot it several times and do that until it actually works. Even though it shows “enabled” it might not be working. After I got it working it will keep working until I have to reboot (which is basically daily because of the issue with the lock screen no longer taking input). In earlier builds (several months ago) after enabling the modem I had to enter my SIM again.
This only started like a year ago. It was working fine with the initial Beta Edition and only showed up after I had the phone for quite a while.
On every reboot I am asked to enter my SIM but that only unlocks the modem and does not enable it.
I was not the only one to have this issue. I got more context about this, as well as the command to enable the modem, with from other users. But I can’t find the post anymore. Maybe I am remembering wrong and just read the post and did not participate.
I only found the report by another user which I commented on: Modem not showing up
Here’s another user with that problem: Calling/texting (sms) with Pinephone Pro
