Why does my iPhone say iMessage needs to be enabled?
In order to send and receive iMessages to your iPhone, iMessage must be enabled. … When iMessage is enabled, iMessages are sent using a Wi-Fi connection or cellular data when a Wi-Fi connection is not available.
Why won’t my iMessages activate?
Make sure you’re connected to a cellular or Wi-Fi network. If you’re using an iPhone, you need SMS messaging to activate your phone number with iMessage and FaceTime. Depending on your carrier, you may be charged for this SMS. Go to Settings > General > Date & Time and make sure your time zone has been set correctly.
