Yesterday morning I ported my number from Spark to Vodafon. All good but then I started getting those messages from iMessage saying activation failed. As usual vodafone recommended to reboot network setting which I did but it didn't help.
I can see my iMessage activates for my @gmail.com address and so does for my @icloud.com, but my nz number keeps failing and never succeeding.
Do I just need to wait a few days and try again or is there any other workaround here?
Is this a prepay connection you have? If so Facetime/iMessages activates by sending a one off 'invisible' txt to a server in the UK. Needless to say this is still an international SMS so if you haven't got sufficient credit the sms will fail.
