Set up cellular on Apple Watch

With a cellular connection on Apple Watch, you can make calls, reply to messages, receive notifications and more – even while you’re away from your iPhone.

Before you start

  • Make sure that you have the latest software on your iPhone and your Apple Watch.
  • Check for updates to your network provider settings.
  • Make sure that you have an eligible mobile data plan with a supported network provider. Your iPhone and Apple Watch must use the same network provider,* and you must be within your provider’s network when you set up cellular on your watch.
  • If you have an enterprise or corporate mobile data plan, check with your company or network provider to see if they support this feature. Pre-paid accounts and some older accounts aren’t currently supported. To make sure that your account is eligible, contact your network provider.

* An Apple Watch that you set up for a family member can use a different network provider than your iPhone uses.

Set up cellular on your Apple Watch

You can activate cellular when you first set up your Apple Watch. During setup, look for the option to set up cellular, then follow the onscreen steps.

You can also set up cellular later from the Apple Watch app:

  1. On your iPhone, open the Apple Watch app.
  2. Tap the My Watch tab, then tap Cellular.
  3. Tap Set Up Cellular.
  4. Follow the instructions for your network provider. You may need to contact your network provider for help.

Set up cellular on a family member's Apple Watch

You can set up a cellular Apple Watch for a family member who doesn't have their own iPhone. If your network provider supports the use of a managed Apple Watch, you're given the option to add the watch to your plan during setup. If your network provider doesn't support it, you may be able to use an alternative carrier. 

To see the phone number assigned to your family member's Apple Watch after you’ve set up cellular, go to Settings on the watch, then tap Phone. 

Setting up a managed Apple Watch for a family member is available only in certain countries or regions.

If you're in mainland China, you must verify your identity when setting up cellular on a family member’s Apple Watch, as required by local regulations. Contact your network provider for further assistance if needed.

Connect to a mobile data network

Your Apple Watch with cellular automatically switches to the most power-efficient wireless available: it can connect to your iPhone when itʼs nearby, a Wi-Fi or cellular network. When your watch connects to cellular, it uses LTE networks. If LTE isn't available, your watch will try to connect to UMTS if your network provider supports it. 

When your watch connects to a cellular network, you can check the signal strength from Control Centre or the Explorer watch face. To open Control Centre, touch and hold the bottom of the screen, then swipe up.

The Cellular button turns white when your mobile data plan is active, but your watch is connected to your iPhone using Bluetooth or Wi-Fi.

Changing network providers

Your iPhone and Apple Watch must use the same network provider, unless the watch was set up for a family member who doesn't have an iPhone. If you change network providers on your iPhone,* you need to remove the previous service plan on your Apple Watch and sign up for a new plan. Here's how:

  1. On your iPhone, open the Apple Watch app. 
  2. Tap the My Watch tab, then tap Cellular. 
  3. Your Apple Watch should automatically switch to the network provider that your iPhone is using. If you need to add a new plan, tap Add a New Plan, then follow the onscreen steps. If your previous plan still appears in the Apple Watch app, you can remove it.

If you need help, contact your network provider. 

* Network provider fees may apply. Contact your network provider for details. 

Transfer your mobile data plan to a new Apple Watch

When you’re ready to start using a new Apple Watch, you can transfer cellular service from your old watch to your new one. Here’s how:

  1. Remove the mobile data plan from your old Apple Watch. You can do this from the Apple Watch app or by erasing your old Apple Watch. 
  2. Pair your new Apple Watch with your iPhone. During setup, tap “Set up Cellular” to add a mobile data plan.
  3. Some network providers allow you to transfer your existing plan to your new Apple Watch directly from the Apple Watch app. 
  4. If you don’t see an option to transfer your mobile data plan, contact your network provider for help.

Remove your mobile data plan

You can remove your mobile data plan at any time:

  1. On your iPhone, open the Apple Watch app. 
  2. Tap the My Watch tab, then tap Cellular. 
  3. Tap the information button  next to your mobile data plan at the top of the screen. 
  4. Tap Remove [network provider] Plan. Tap again to confirm. 
  5. If you aren't going to pair again, you may need to contact your network provider to cancel your mobile data subscription.*

When you erase and unpair your Apple Watch, you also get the option to remove the plan from your Apple Watch. When asked, choose Erase All to remove the plan. 

* Network provider fees may apply. Contact your network provider for details. 

About international roaming

  • Cellular roaming isn't supported outside your network provider network coverage area.
  • To cover the LTE and UMTS bands used around the world, cellular models of Apple Watch come in regional models for the Americas, China mainland and Europe/Asia Pacific. Unlike iPhone, there isn't a worldwide Apple Watch model that supports all cellular bands used globally.
  • When your Apple Watch is connected to your iPhone or a previously joined Wi-Fi network, you can still use all the features of your Apple Watch, even if cellular isn't available.
