If your Apple Watch isn’t connected or paired with your iPhone
If you see a red iPhone icon on your Apple Watch, or you’re trying to pair and can’t find the ‘i’ icon, try to connect your devices again.
Check your Apple Watch connection
If you don’t get notifications, messages or calls on your Apple Watch, your Apple Watch and iPhone may not be connected.
When your devices aren’t connected, the red iPhone icon
or the red X icon
will appear in Control Centre. When your Apple Watch connects again, the green iPhone icon
appears.
Bring your Apple Watch and paired iPhone close together. If your watch shows that the devices are still disconnected, try the steps below. After each step, see if your devices can connect.
Try to connect your Apple Watch and iPhone again
Keep your Apple Watch and paired iPhone close together to make sure they’re in range.
On your iPhone, swipe down from the top right-hand corner of your screen to open Control Centre, then make sure Airplane Mode is off and Wi-Fi and Bluetooth are on.
On your Apple Watch, press the side button to open Control Centre, then make sure Airplane Mode is off.
Unpair your devices, then pair them again
If your Apple Watch still can't connect, unpair it from your iPhone, then pair your Apple Watch and iPhone again.
