Apple Watch Support & Set Up

To get started:

To set up and use a new Apple Watch, you need iPhone XS or later with iOS 18.0.1. Learn how to identify your iPhone model and how to update your iPhone to the latest version of iOS.
Make sure that your iPhone has Bluetooth turned on and check that it's connected to Wi-Fi or a cellular network.
Download apps you want to use on your Apple Watch. Apps must be downloaded on both the phone and the watch to sync data.
Your iPhone should have the Apple Watch app already installed. If not, download the Apple Watch app from the App Store.
If you have not setup a Cellular plan on your Watch, you will have the option to activate services during your initial setup. See the Add a Watch Rate Plan section to complete your Watch activation.

Center your watch face in the camera on your iPhone. Wait for a message to say that your Apple Watch is paired. If you can't use the camera, or the pairing animation doesn't appear or your iPhone can't read it, select Pair Manually, then follow the prompts.
Next, select Set Up as New Apple Watch. If asked, update your Apple Watch to the latest version of watchOS. Once completed follow the prompts to customize your Watch.
If you've set up another Apple Watch with your current iPhone, a screen appears that says Make This Your New Apple Watch.

If asked, enter your Apple ID password. If you aren’t asked, you can sign in later from the Apple Watch app: select General > Apple ID, then sign in.
Certain features that require a cellular phone number won’t work on cellular models of Apple Watch unless you sign in to iCloud. Note: If Find My Device isn't set up on your iPhone, you'll be asked to turn on Activation Lock.
If an Activation Lock screen appears, your Apple Watch is already linked to an Apple ID. Enter the email address and password for that Apple ID to continue.
Create a passcode. On your iPhone, select Create a Passcode or Add a Long Passcode, then switch to your Apple Watch to enter your new code. To skip, select Don't Add Passcode. Note: You can skip creating a passcode, but you need one for certain features like Apple Pay.

Customize your settings such as preferred text size, fitness details, and notification levels.
You'll also be asked to set up Apple Pay by adding a card. Your iPhone walks you through features like the Always On display and your preferred app view.
Keep your devices close as they sync. Your Apple Watch shows the watch face when the pairing procedure is finished and your watch is ready to use. Note: Keep your Apple Watch and iPhone close together so the devices can continue syncing information.

If you recently purchased your Apple Watch and have not activated service, review the steps to activate your device now.

Once you've turned on and setup your Watch, open the Apple Watch app on your iPhone.
In the Apple Watch App Select Cellular > Set Up Cellular.
You will be prompted to sign in to your Metro Account. Enter your Metro by T-Mobile Account PIN.
Select a Metro by T-Mobile Apple Watch rate plan > Enter your E911 Address > Enter your Payment Details > Agree to the Terms & Conditions to finish setting up your device.
