I don't even understand the "iPhone Cellular Calls"-option under Facetime-settings on my iPhone.
It's turned off, and when I try to turn it on, I get a message saying "Facetime and iCloud needs to be logged in to the same iCloud-account" (I'm not 100% on the wording, as my iOS is in my native language, Danish).
The odd thing is, both Facetime and iCloud ARE logged in to the same iCloud-account! But I still can't enable this setting.. I've tried rebooting, logging out and back in, hard reset (or whatever home+sleep-button for 10 secs is called)
Nothing lets me turn the darned thing on! 🙁
