There are a few of us having issues getting iMessage in iOS7 to activate on the Telecom Network.
See this thread over on the Apple iOS forum: http://www.geekzone.co.nz/forums.asp?forumid=76&topicid=133468&page_no=1#920660
One of the theories is that the return SMS message is somehow getting blocked.
I wondered if anyone from Telecom who monitor this forum could suggest a way for checking this out or who to contact?
