- To receive SMS, MMS, or push notifications from third-party apps on your Apple Watch Series 3 (GPS + Cellular), your paired iPhone must be powered on and connected to Wi-Fi or cellular, but it doesn't need to be nearby. You also need to be signed in to iMessage on your iPhone.
- If you're on Wi-Fi and want to call a phone number, make sure that Wi-Fi calling is turned on for your Apple Watch. Otherwise, try making a FaceTime audio call.
- For GPS accuracy when you walk, run, or cycle outdoors, select the appropriate Workout and bring your iPhone. For GPS accuracy, you can also calibrate your Apple Watch. Apple Watch Series 2 or later has built-in GPS that allows you to get more accurate distance and speed information during an outdoor workout without your paired iPhone.
