I noticed some time ago that activation of iMessage on my IPhone 5S was unsuccessful but havant got around to sorting it until now.
The last couple of days I keep seeing a pop up which whether I accept or not keeps coming back, it says ‘iCloud Your carrier may charge for SMS messages used to activate iCloud.’
I also get a similar one but saying iMessage instead of iCloud.
Suffice to say, under Settings -> Messages it says ‘Activation unsuccessful Turn on iMessage to try again’
I’ve tried a network reset but no difference.
Any ideas please?
