What the hell is going on with connection?

Hello @nika_ishan‌,

did you try to restart your phone already? Turning it off completely and starting it new then?

After doing that the sim card will connect completely new with the network, which might help.

If that doesn't help: Did you try the Live-Check already?

The last two days there were some network problems.

Today it should all be fine again, but it is possible that at some places there is some kind of a network issue.

Which is the postal code where you have a confinement?

Kind regards,

Jessica
