Are you suddenly unable to send or receive iMessages (or text messages) from your iPhone? When you attempt to send an iMessage or text message you get a not delivered message or an iOS system message below.
Cannot Send Message
IMessage needs to be enabled to send this message.
In addition, you probably already checked that iMessage was enabled in your iOS iPhone settings (Settings -> Messages).
Here’s what most likely happened – you probably disabled (by mistake) your cellular antenna connection in Control Center on your iPhone.
- On your iPhone home screen, swipe up to reveal your iPhone control center.
- Check to see if your iPhone Cellular Antenna connection is disabled. If it is, enable it.
Try to send iMessage / text messages again.
If the problem persists, try to reset your iPhone network connection settings.
