Question regarding modem

[AntonReiser]

I believe pine64,pinephone-1.0.toml, pine64,pinephone-1.1.toml and pine64,pinephone-1.2.toml are for Pinephone versions 1.0, 1.1 and 1.2 respectively. If you modify the relevant file in /usr/share/eg25-manager directory then eg25-manager will use those but they are overwritten with defaults whenever there is an eg25-manager update (the config file parameters seem to change, presumably trying to improve modem / phone stability). So your changes will be undone every time there is an update in eg25-manager.

To avoid that problem copy the relevant file to a newly created folder in /etc (all sudo) called eg25-manager and modify it as required.
The only problem with that is whenever there is an update you don't get any new improved settings for eg25-manager, so I recommend copying /usr/share/eg25-manager/ file to /etc/eg25-manager/ folder and modifying it again just to be sure (or just diff file1 file2 to see if there are any actual changes).

Otherwise just modify the file in /usr/share/eg25-manager directory and worst case it gets overwritten with an update but you know that you just modify it as required, easy to do via command line and ssh, right?

Hope that clarifies things.

It's easy enough to try it out for any of the files if you don't know which one will work, just update the file and save it and reboot, then test with the relevant AT command.

When will 3G be switched off in Germany? Have you tried the settings in the forum post I gave the link to? I only mentioned 4G calls for O2 but no SMS, so not sure if that would solve the SMS issue. Just curious as to the automatically selected profile, if it's not ROW_Generic_3GPP then ROW_Generic_3GPP could get SMS working too, but no guarantees, of course.

Great, I think the issue is solved now.

Since I have added the aforementioned line to the file pine64,pinephone-1.2.toml, the phone boots with the setting '+QCFG: "ims",2,0' and sends SMS messages! (Except for one case in the test series, in which it was 2,1. I will keep an eye on that.)

With regard to 3G: I just read that my carrier apparently switched it off some months ago. When I set it to "3G only", it still shows the connection bar, but (which had escaped my attention) no network name and it does not make calls. No wonder I could not send messages with force 3G.

I was under the (maybe wrong) impression that it would not help to try the forum post, because it ended with "--> response should be '+QCFG: "ims",1,1'" which was the default setting on my phone anyway.

I think "ROW_Generic_3GPP" is the automatically selected profile, at least the phone tells me

Code:

response: '+QMBNCFG: "List",0,0,0,"ROW_Generic_3GPP",0x05040820,202009031
+QMBNCFG: "List",1,0,0,"VoLTE-ATT",0x0501033C,202004261 (...)

Anyway, after being really frustrated with my new pinephone I am extremely happy now that it works!

Thank you for your effort and your patience!
