To live and die on LTE (with a Pinephone)

Code:
/usr/lib/udev/rules.d/80-modem-eg25.rules

ACTION=="add", SUBSYSTEM=="usb", DRIVERS=="usb", ENV{DEVTYPE}=="usb_device", ATTRS{idVendor}=="2c7c", ATTRS{idProduct}=="0125", ATTR{power/control}="on"

if biktorgj is recommending this, it tells a hint. (although for pinephone sdk, i recommend for both stock and pinephone sdk). this fixes constant modem disappearings and occasional die outs.

i use lte (4g) only mode almost all times. some special commands like call waiting commands and call divert commands does not work in lte (in most of a time), so i use older network technolgies some cases.

I changed the modem settings when I first started investigating the issue. In retrospect, I wish I'd investigated a little more before making the change to get some hard data about "modem coma", but my feeling is it seems to happen less frequently with the change.  And missing fewer calls from my wife is pretty much the only goal. Wink (Although the "modem gone" audio warning at midnight last night wasn't such a good idea either . . .)

I use 4g only, since my network only supports 4g now. But when something happens, the setting gets changed automagically from "current: allowed: 4g; preferred: none" to "allowed: 2g, 3g, 4g; preferred: 4g" without me doing anything. And that seems to happen when phone service disappears -- which seems like a reasonable hypothesis. I'm still trying to figure out exactly what the something is, but now I have a script watching the config and logging unexpected changes and playing an audio file when that occurs.
