I ported my number over from Vodafone to Spark this morning and now iMessage won't activate. I know there have been some threads about this before and I read through them, but they were quite old and I was wondering if it is still just a matter of waiting for it to work?

I called Spark and told me that they don't support 3rd party apps and to call Apple, and Apple told me to wait 24 hours and then contact them again if it's not working.

It seems that I should have deregistered my number with Apple first and that sometimes help, but I didn't and now my phone won't receive that text message code to deactivate it either, so I seem to be out of luck for now :( All other text messages are working though, just not the one from Apple.

Is there anything else I can do?
