Set up cellular on Apple Watch for yourself

Usually, you can enable cellular service on Apple Watch during the initial setup by following the onscreen instructions. It could also be set up later; however, before we go through the steps, let’s check out some prerequisites.

Requirements to set up cellular on Apple Watch

• Apple Watch compatibility – Ensure you’re using a cellular model Apple Watch Series 3 or above.
• Cellular plan support – Cellular service is not available in all areas or with all carriers, so check Apple’s website to see if you have an eligible cellular plan.
• Carrier clause –
  • The iPhone and Apple Watch must use the same carrier when setting for yourself.
  • When setting for a family member, they can have different carriers.
  • If using an enterprise or corporate cellular service plan, check with the company if the cellular plan is supported.
• Be in the range – When setting up cellular on Apple Watch, you must be within your carrier’s network range.

How to activate cellular on Apple Watch

1. Launch the Watch app on your paired iPhone.
2. Tap the My Watch tab.
3. Here, tap Cellular → Set Up Cellular.
   The steps from here might vary depending upon the carrier; follow the onscreen instructions.

If you need some assistance, call the carrier provider. Once the setup is complete, your Apple Watch cellular network is ready to use. But before anything else, let’s test out whether cellular is working or not.

Connect Apple Watch to a cellular network

By default, Apple Watch selects the most power-efficient network available, whether it’s a Wi-Fi network or a nearby iPhone. So, to test the Apple Watch cellular, turn off the Wi-Fi and Bluetooth (disconnects the iPhone).

To turn on the cellular network on Apple Watch

1. Open the Control Center (swipe up from the bottom of the screen).
2. Check if the cellular icon is:
   • Green = On
   • White = Off
3. If it’s white, touch and hold the icon to turn.

Now, try to make a call, message, or open an app that requires a connection to check whether cellular is working on the watch or not. If it’s not working, try this troubleshooting guide to resolve the issue.

To turn off the cellular network on Apple Watch – Go to Control Center → long-press the cellular icon; it should turn white.

Set up cellular on Apple Watch for a family member  

Available from watchOS 7 and later, you can set up a family member’s watch (kids or elderly) who might not have their own iPhone. Once set up, they can make calls, send messages, share locations, etc.

Requirements to set up cellular on a family member’s Apple Watch

• Apple Watch – Series 4 or later with cellular or Apple Watch SE with cellular running watchOS 7 or later.
• iPhone – iPhone 6s or later with iOS 14 or later.
• Cellular carrier support – Your carrier should support Apple Watch cellular.
• Apple ID –
  • Your Apple ID with two-factor authentication enabled.
  • Family member’s Apple ID to use in the Apple Watch.
• Family Sharing – Your Family Sharing setup should include the Apple ID of the Apple Watch user. Plus, you should be the organizer or parent/guardian to complete the setup.

Note: Do check Family Setup availability in your area; it’s not available in all countries and regions.

Activate cellular on a family member’s Apple Watch

You can either enable cellular on a family member’s Apple Watch during setup. But if you’ve missed the opportunity, here’s how to do it later:

1. Open the Watch app on your iPhone.
2. Tap All Watches
3. Select your family member’s Apple Watch → tap Done.
4. Tap Cellular → Set Up Cellular.
5. Follow the onscreen instructions; you might have to contact the carrier for help.

Note: After setup, go to Settings on the family member’s watch and tap iPhone. Here you can check the phone number assigned to the watch.

Transfer cellular plan from your old Apple Watch to new one

Are you transferring to a new Apple Watch? No worries, follow these steps to continue using your cellular plan on the new device without a hiccup.

1. Remove the cellular plan from the old Apple Watch (steps mentioned below).
2. Pair the new watch with your iPhone.
3. Select Set up Cellular during the setup.

Notably, some carriers allow you to transfer the existing plan directly from the Apple Watch app. Just follow the onscreen instructions. However, if that option is missing, contact the carrier for assistance.
