Other phones behave this way.
C2 actually doesn’t.
The SIM you have set to 4G doesn’t recognize incoming calls but you can make outgoing calls-

In german it is Einstellungen->Mobiles Netzwerk->Netzwerk Modus (SIM 1 or 2).
In english it should be something like Settings->Mobile Network->Network Mode.
Mode should be selectable for each SIM-Card separateliy.
There is no support for VoLTE (4G) built in 5.0.0.21. We’ll have to wait for another release.

Yes. And while we’re waiting it helps to switch to 2G or 3G as preferred network.

I have set 3G as preferred network, Calls are working. C2 has on right upper corner 2.5G.

Danke @jcoder, I have looked into the settings as you suggested and have set teh active sim to preferred 3G. Tried calling the C2 and yess!! calls are arriving on the C2.
I hope that in the near future that the Jolla-boys soon will be able to put out an update which will then make it possible to use the other frequency 4G.
The German instructions helped me out, I live in Niederlände that doe make things a bit easier.

There’ll be no 5G
4G is the maximum supported by C2’s hardware

Jolla C2 feels nice and I like the bigger screen. However what I do miss a lot is the following:
-
No predictive text input (!!)
It seems that XT9 has been removed from the Jolla Store, there is no way to have spellcheck and/or predictive text input. This a basic feature and hard to live without… -
No Chinese language input (this works very well on Sailfish 4.6)
-
No Chum store (yet) so therefore some apps missing, so no Privoxy available to use with Tor, no Wireguard? Only way to secure my connections are via OpenVPN…?
-
No video recording possible (both the Camera and the Advanced Camera freeze/crash when trying to record a video)
Especially the predictive text input I’d say is a rather basic but vital feature if you plan to write more than a few words of text on your device.
Apart from the above I like the look and feel (apart from maybe the camera part).

Install the chum rpm and change the OS to 4.6.0.25 - it works! 
OK that will be nice, but the main question is how!? Please feel free to enlighten us with a tutorial how to flash SFOS 4.6 on C2 hardware and where do you get the image file …
Change the OS version in the Chum settings just by writing 4.6.0.15 in the dedicated field.

After installation of the chum package I have no app starter and even in storeman I get no “start” in the drop-down menu …
Isn’t it 4.6.0.15?

4.6.0.15 (not 4.6.0.25)!
P.S.: Please pay much attention to provide correct advice, otherwise such advice may be outright evil, because it frustrates newbies and may result in broken installations (not in this specific case, because 4.6.0.25 is luckily just invalid).

Hey olf nice that you are here to help, but maybe you can tell me how I can get chum installed and started under the C2 … The storeman installed chum, but I get no app starter, when I try via shell to start it, it claims that it has not the proper start parameters and I can’t find any documented start parameters … I tried also to install just the rpm from github, but same result … Can youmaybe help me?
Can you start chum from command line?
maybe you need change also the chum repo version in the repository (inside /etc/ssu/ssu.ini) to get chum installed correctly.
its linux, guys! Use command line!

Done.
Also done, see Storeman 0.7.1 and 0.7.2.
TL;DR
Storeman Installer works fine now on any SailfishOS release (≥ 3.1.0, that is) and should continue to do so with future SailfishOS releases (e.g. 5.0.0.x, 5.1.0.y etc.).
Thus, as originally stated:

No, you installed the SailfishOS:Chum Installer from OpenRepos by the help of Storeman.
The SailfishOS:Chum Installer fails, because the SailfishOS:Chum community repository is not ready for SailfishOS 5.0 yet, as you can see in its log-file (RTFM) and its systemd-journal entries.
… I tried also to install just the rpm from github, but same result …
If you pick the right one, that should work.
Can youmaybe help me?

As Storeman / Storeman Installer and the SailfishOS:Chum GUI application / its Installer do work as advertised in their corresponding documentation (i.e. absolutely fine now for Storeman / Storeman Installer and with a manual workaround for the SailfishOS:Chum GUI application) I will mute this thread for me, because I do not own an Jolla C2.
Additionally, all questions here WRT these two topics were answered by me in this discussion thread, even though these answers were already provided in the corresponding documentation.
Actually I perceive asking here at FSO, because it is easier than following web-links and reading documentation first, as quite rude!
If you have read the documentation exhaustively and you either do not comprehend the documentation (which would constitute a flaw of that documentation) or are convinced that a technical issue exists (which must be reproducible), please file a proper bug report at the correct location (i.e. at the issue tracker of the appropriate GitHub repository), as advised in the documentation.
In general, chatter in this forum (usually just “does not work for me”) is never a proper bug report for a third party software developer (i.e. ≠ Jolla).
I hope that experienced FSO and SailfishOS users will provide newbies with a link to answers already provided at FSO and / or (even better) the appropriate user documentation at OpenRepos.
Thanks!
P.S.: Please bear in mind that the current SailfishOS releases for the Jolla C2 have the status of what is usually called a “cBeta (closed / community beta)” release by Jolla, i.e. a “early beta” (“EA (early access)” releases are the betas after the cBeta releases and before the first “GA (general availability)” release of a SailfishOS release X.Y.0).
Furthermore, the current batch of Jolla C2 phones was explicitly advertised as being developer devices, hence it is not at all surprising that many things do not work. Yes, the phrase “SailfishOS as it is meant to be” is laughable, but that is a dire tradition of Jolla marketing communications; I assume they meant “We hope that we will be able to deliver a SailfishOS experience as it is meant to be on the Jolla C2 in the future” (i.e. “soon™” in Jolla’s parlance).

Yesterday the C2 arrived. It had 80% battery. I plugged the charger in and after a few hours I tapped twice on the screen to see if the battery was full. Setting up went smooth, I sat close to our router. I choose English. Wifi is ok.
Not everything works as it should be (apps from Aurora and F-Droid don’t show up, the pulley menu doesn’t have a push, no incoming calls, etc.) but I expect all this will be solved in the future. I did not yet install Sailfish 5.
To my amazement the browser had Google as default (For years I use Qwant or Duckduckgo). There is no list of search engines other than the big four. The thumbnails are new. In search (Bing) the text is small while I had set the text in setting on huge.
For me the C2 is a set back, not because of the omissions in the OS, that are expected to be temporarily, but because of the hardware:
the sides of the C2 hurt my fingers so I cannot hold it longer than one or two minutes and the other nuisance is the sound. The sound is not suitable for persons with damaged hearing like me. Hearing aids don’t make the sound better, on the contrary. I realise how lucky I was/am with the text adaptation, the rounded sides and the excellent sound of the XA2 and XA2 plus.
This is why I want to return the C2 on my cost. Or someone else in the community is interested?
