Settings for Sipgate provider
I am getting in my pinephone mobian system the following messages in the logs:
ago 06 10:24:23 hostname mmsdtng[791]: Your MMS settings are not in the database! Please file a merge request at https://gitlab.gnome.org/GNOME/mobile-broadband-provider-info so they can be added
ago 06 10:24:23 hostname mmsdtng[791]: Could not find settings: Operator ID '26203' not found in service provider database
My provider is Sipgate, which seems indeed not to be in the list of German providers. The settings can be found in the support page https://help.sipgate.de/hc/de/articles/4414330920721-Smartphone-f%C3%BCrs-Surfen-konfigurieren (in German): name: sipgate APN: sipgate username: sipgate password: sipgate MCC: 262 MNC: 03
So I guess it makes sense to add that setting. Having said that, Internet connection worked out of the box, so I didn´t need to add this manually to work, although interestingly the default settings were different (I guess it is because the automatic settings come from an old SIM card, which maybe has old settings stored in it). Also, the message in journalctl is actually about MMS, but this provider explicitly states that MMS is not supported (see point 4.7.2 in page https://www.sipgate.de/leistungsbeschreibung, also in German).
