We have 2 iPads and FaceTime and iMessage stopped working on both of them! Works fine on iPhone but not iPad. Both iPads are WIFI only. Any suggestions?
Settings > WiFi > find the active wifi network ( the one with the tick)

Click the blue arrow> find the DNS entry ( 4th item down), note its value.

In the DNS field type in 8.8.8.8

Click the home button and then try iMessage and Facetime.
