Thanks again for this comprehensive guide, @dcinoz.
From what I believe to have understood I would want VoLTE to be enabled and IMS disabled.
VoLTE seems to be enabled since 4G connections remain active when making calls and since the IMS/VoLTE Status normally is 1,1 and becomes 0,1 after doing the QCFG="ims",0' command.
Unfortunately, in both cases the phone did not send text messages even though it could receive them.
What I have discovered though (without knowing if it is new or simply something I had not noticed before) is that the phone sometimes can send exactly one text message immediately after restart.
This seems to coincide with the fact that immediately after restart the IMS/VoLTE status is '+QCFG: "ims",1,0' and not 1,1 (which it is when I wait a little while before doing mmcli -m any --command='AT+QCFG="ims"').
Could that be a hint what the solution might be? And if it is: How can I set the value to 1,0 in order to find out if that does the trick?
