Telstra iMessage Activation Problem Status
Thought I'd start a specifc topic relating to iPhones on the Telstra network that can't get iMessage and Facetime activated as the original thread is also dealing with other iMessage issues unrelated to Telstra.
Original discussion here: https://discussions.apple.com/thread/5318987?start=0&tstart=0
To summarise,
New iPhone5x and old phones updated to ios7 that needed to be activated for iMessage seems to be having problems registering their mobile number with Apple's iMessage (and Facetime) servers. Some people have got iMessage working with their Apple ID, but that isn't the problem, it's having their carrier number activated with iMessage.
If you have success with your Telstra phone please let us know on this discussion so we can check to see if ours is also working.
