IMessage Activation Unsuccessful
I have been trying to switch my AppleID contact to my icloud address and I am unable to do so. Therefore, I am unable to use Imessage or FaceTime applications. I AM able to receive Network/Contact SMS texts. Applications that require data/WiFi connection e.g. WhatsApp, Instagram, Facebook also WORKS FINE. I have attached an image of the Error message that arises when the switch is attempted. Please Help. :(
iPhone 8 Plus, iOS 12
