- Open the Settings app.
- Tap Messages.
- Tap the switch next to iMessage. You’ll know iMessage is off when the switch is positioned to the left and gray.
- Tap the switch again to turn it back on. You’ll know iMessage is back on when the switch is green and positioned to the right.
Why this works:
Turning iMessage off and back on can sometimes fix a minor software issue when your iPhone is not receiving iMessages. Think of it like restarting your iPhone, but specifically for iMessage.
