Imessage and facebook will not activate
I have changed my apple ID password, and since then my imessage and facetime will not activate, it says: "Could not sign in. Please check your network and try again." My internet connection is fine, my username/new password have been entered correctly, my time/date are correct, I have the latest software installed, and I have turned it on and off again, yet the same problem keeps arising.
Could anybody help (I have the iphone 5, if this helps).
Thank you in advance.
iPhone 5, iOS 7.1.2
