Hi Walter, 

From which modem firmare version did you update to which version?

The problem only occurs on my pinephone with the modem firmware version 01.002.01.002 whereas
the pinephone with firmware version 01.001.01.001 does send SMS messages without any problem.

After the discovery that immediately after restart the IMS/VoLTE status is 1,0 for some time (before it becomes 1,1) and that immediately after restart the phone can send at least one text message (see above),

I checked the IMS/VoLTE status on my other, flawlessly working pinephone:

It's 1,0!

So setting it from 1,1 to 1,0 might indeed solve the problem.

How would you do that?

And, in case this works: How can the status be changed permanently?

That's great!
See my previous post for eg25-manager configuration, change the IMS config.
This what you need to change to disable VoLTE support even after reboot:

Code:

# Enable VoLTE support
#    { cmd = "QCFG", subcmd = "ims", expect = "1" },
    { cmd = "QCFG", subcmd = "ims", value = "2" },

It works for my Pinephone so should for you as well.

Weird that 4G calls work if VoLTE is 0 as then calls should switch to 3G....no idea about the AT+CFUN though I understood it as being a reset...I might try with my Pinephone over the weekend. Note that by default eg25-manager has IMS set by MBN so enabled for you it seems.

Thanks, @dcinoz !

What I had not understood: Where do I have to save these lines? 

In /usr/share/eg25-manager there are three files: pine64,pinephone-1.0.toml, pine64,pinephone-1.1.toml and pine64,pinephone-1.2.toml

They all contain these lines

Code:

# Enable VoLTE support

    { cmd = "QCFG", subcmd = "ims", expect = "1" },

Do I have to exchange them in all three files with the lines you posted? And did I understand it correctly that I should copy the directory eg25-manager to  /etc? (Sorry for asking, but I'm a bit afraid of breaking things.)

Regarding the 4G calls: When response: '+QCFG: "ims",2,0' then the phone sends messages and it does indeed do 4G calls, or at least it keeps showing the "4G" on the display when having called or been called. On the other, older pinephone (with firmware version 01.001.01.001) it drops to 2G immediately when making calls. (By the way: While force 3G on the new phone [which we had tried in the course of our conversation] did not change the SMS problem, I later discovered that force 2G does: With only 2G enabled the phone can send messages.)

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.
