I can't sign into Messages or FaceTime on my iPad

My daughter recently gave me her old iPad and we have restored all settings before setting it up as a new iPad with my AppleId. All other AppleID services are working as expected, however I get an error whenever I try to sign-in on Messages or FaceTime.

I've followed all the advice I can currently find on the subject, checked TimeZone, reset the iPad again, logged out etc., etc. and waited for over a week to see if that affected activation. My son and daughter have both tried logging into FaceTime on the device and it works fine for them, so l'm drawing the conclusion that it is something to do with my AppleId. With that thought in mind I created a completely new AppleId and reset the iPad again and set it up with the new ID. Same problem. I'm complete baffled as to the problem as I can use both my AppleIds for FaceTime on my old iPhone 4 over Wi-Fi.

can anyone suggest a solution?
