nice update

seems to also have fixed my problem with calls not working again after a restart so now I don't have to mess with the cellular settings every time I restart the phone anymore.

Allright got it working again.

Connection type:
2G/3G/4G

APN is set to:

Name: Vodafone
APN: web.vodafone.de

turns out every time I do a restart calls completely stop working, but I've found a method that seems to be working reliably:

When restarting always Power off instead of using the restart option.
Once everything is back on go to the Carrier & APN settings tick the little box next to your APN again
then manually select the carrier again.

My Calls stopped working again after a restart, did not change any settings.

I somehow just managed to make a call after I set it to 2G/3G/4G and APN Name Vodafone, restarted the phone and then just clicking on Carrier.

I'm happy now

I went to System Settings -> Cellular and tried all the connection types and the options under Carrier & APN

Hi, I'm having the same issue tried all the options I could find but just can't get phonecalls to work.
I'm in Germany carrier is Vodafone.
