Jul 7, 2015 10:29 AM in response to klobasozrutby ChrisJ4203,You cannot update your device to iOS 8.3. If you just did an update, then it had to update to iOS 8.4, unless your device is jailbroken or hacked. When you say that iMessage fails, what error message do you see?

Jul 7, 2015 12:49 PM in response to ChrisJ4203by klobasozrut,I did the update last week, the ios 8.3 were actual.
The eroor message is
"Aktivácia iMessage
Nepodarilo sa prihlásiĆ„. Skontrolujte pripojenie k sieti a skúste to znovu"
this is of course in Slovak, in English it means something like
"Activate iMessage
Unable to login. Check the network connection and try again."
But, of course, the internet connection works perfectly.

Jul 7, 2015 11:57 PM in response to ChrisJ4203by klobasozrut,Yes, of course I do (Slovak Telecom, formerly T-Mobile).
I`ve actualised the password and the credit card on my Apple ID. And then I repeately tried to connect to iMessage service on my iPhone. That`s all, I don`t know what troubleshooting should I try in this case...
