Set up and use cellular on Apple Watch Series 3 (GPS + Cellular)

With Apple Watch Series 3 (GPS + Cellular) and a cellular connection, you can make calls, reply to messages, receive notifications, and more, with just your Apple Watch. Even when you aren't connected to your iPhone or Wi-Fi.

    

Here's what you need

Before you set up cellular, check for updates to your carrier settings.

If you have an enterprise or corporate cellular service plan, check with your company or carrier 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 carrier.

Set up your cellular plan

You can activate Apple Watch Series 3 (GPS + Cellular) when you first set up your Apple Watch. During setup, look for the option to set up cellular, then follow the onscreen steps.

Or you can set up cellular later:

  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 carrier. You might need to contact your carrier for help.

Connect to a cellular network

Apple Watch Series 3 (GPS + Cellular) will automatically switch to the most power-efficient wireless available. It can connect to your iPhone when itʼs nearby, a previously joined Wi-Fi network, or cellular. Your Apple Watch can connect to LTE networks. If LTE isn't available, your watch will try to connect to UMTS if your carrier supports it. 

When your watch connects to a cellular network, you can check the signal strength from Control Center or the Explorer watch face. To open Control Center, swipe up on the watch face.

Control Center

The Cellular button turns green when you have a connection. The green dots show the signal strength. 

Control Center

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

Changing carriers

Your iPhone and Apple Watch Series 3 (GPS + Cellular) must use the same carrier. If you change carriers 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 plan should automatically switch. 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 carrier.

About international roaming

  • Cellular roaming isn't supported outside your carrier network coverage area.
  • To cover the LTE and UMTS bands used around the world, Apple Watch Series 3 (GPS + Cellular) comes in three regional models – Americas, China, and Europe/Asia Pacific. Unlike iPhone, there isn't a worldwide Apple Watch Series 3 model that supports all cellular bands used globally, so it isn't possible for Apple Watch to roam.
  • 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. 

Learn more

  • To check your cellular data usage, use the Apple Watch app. Open the app on your iPhone, tap the My Watch tab, tap Cellular, then scroll to the Cellular Data Usage section. 
  • To turn your cellular connection on or off, swipe up from the watch face to open Control Center. Tap Cellular icon, then turn Cellular on or off.
  • Turning on cellular for extended periods uses more battery power. Also, some apps might not update without a connection to your iPhone.
