IOS – Can’t switch iMessages on

iosmessages

I can't switch iMessages ON anymore (it was ON).
When I try to flip the switch from OFF to ON it instantly returns to OFF (I don't see any message like "activating…", it just doens't flip). So I don't think it's a server problem because the iPhone isn't even trying to connect. It's like te switch is broken.

I try'ed/checked

  • restart
  • hard reset
  • resetting the iPhone settings
  • changing Wifi network and switching to mobile internet
  • there are no restrictions (they are off)
  • Facetime works (I can turn it on/off)
  • Date & time are correct
  • I can send iMessages via Messages on my iMac
  • Googling
  • Plain SMS messages work fine
  • I can log in and out on my iCloud account

I did make a change to my AppleID. Move my mobile number from "home number" to "mobile number" (http://snag.gy/ze6Ip.jpg) because iMessages didn't work with my mobile number anymore. I tried reverting this changed without succes.

Anyone has an idea how I can fix this?

I created a new (iCloud) backup, wiped the phone and restored my backup. Not really a decent solution, but iMessages works again and I didn't lose anything.
