Use Apple Watch without its paired iPhone
Use your Apple Watch without your iPhone nearby
With Apple Watch with cellular and an activated cellular plan, you can stay connected even when away from your iPhone. For all other models of Apple Watch, there are still things you can do even when you are away from your iPhone and not connected to Wi-Fi.
Use transit cards and use your student ID card
Use the watch, world clock, alarms, timers, and the stopwatch
Check your heart rate, edit your sleep schedule, measure your blood oxygen levels, track menstrual cycles, and relax and breathe mindfully
Apple Watch has a built-in GPS that allows you to get more accurate distance and speed information during an outdoor workout without your paired iPhone. Apple Watch also has a built-in barometric altimeter to get more accurate elevation gain/descent information. The always-on altimeter in Apple Watch SE, Apple Watch Series 6, and later is even more accurate, showing your current elevation in real time.
If your Apple Watch is connected to Wi-Fi
When your Apple Watch is connected to a Wi-Fi network, you can still do the following (even if your iPhone is turned off):
Get apps from the App Store
Make phone calls (make phone calls if you have Wi-Fi calling enabled or want to make a FaceTime audio call and you’re within range of a Wi-Fi network)
Stream music, podcasts, and audiobooks to your Apple Watch
Use third-party apps that support Wi-Fi connectivity
Your Apple Watch uses Bluetooth® wireless technology to connect to its paired iPhone and uses the iPhone for many wireless functions. Your Apple Watch can configure Wi-Fi networks on its own, and also connect to Wi-Fi networks you’ve set up or connected to using the paired iPhone. For more information, see the Apple Support article About Bluetooth, Wi-Fi, and cellular on your Apple Watch.
