I was excited to see that restarting eg25-manager might get a modem that's gone missing back online. I can restart eg25-manager without any errors but unfortunately in my case, it doesn't help Sad So far the only sure-fire method I've found is to restart the device. I'm considering automating a call to reboot when the modem disappears, but for now I just have the phone play an audio file every minute to remind me to restart.

I've also seen a second problem that I intend to see if an eg25-manager restart might help. Every so often my phone loses its LTE connection, and when this happens I can't place or receive calls. Since it's not readily apparent if I'm not getting a call because no one's calling or because LTE is off in the weeds, this is also a problem. So again, I play a sound to tell me to check the phone. I thought that mmcli -m 0 -e might fix things but that experiment failed. Sometimes LTE comes back on its own . . .

I'll post if I find anything else of note.


Hmmm. restarting eg25-manager might actually have worked after all. I tried it when LTE service dropped out and it didn't appear to help when I rechecked the output of mmcli -m 0|grep access. But the modem had returned as modem 1, and I was just assuming it would be restarted as modem 0 again. I'll have to wait for the modem to disappear again to retest this.

Late reply, but for those wondering you can run mmcli commands with 'mmcli -m any' instead of specifying a specific number when the modem inevitably crashes and comes back.
