Apple Watch​

note

5G Apple Watches (Series 11, Ultra 3, SE 3) are supported but will only connect via LTE for now.

Apple Watch plans are available in two modes:

  • Companion mode — your watch shares the same phone number as your iPhone (available on Warp)
  • Standalone mode — your watch gets its own number, even without an active US Mobile line on your iPhone (Warp only)
note

You need an iPhone 6s or newer to activate an Apple Watch. Visual Voicemail won't work in Standalone mode on 5G Apple Watches.

Setting up companion mode​

note

Make sure your iPhone and Apple Watch are signed in with the same iCloud account. When pairing, choose For Myself / Personal Use.

warning

Do not select "Set Up Cellular" during or after pairing — companion mode activates automatically over the air. Selecting it will cause errors.

  1. Bring your Apple Watch close to your iPhone and wait for the pairing animation.
  2. Select Continue on your iPhone, then Set Up for Myself / Personal Use.
  3. Confirm the same iCloud Apple ID is signed in on both devices and follow the on-screen steps.
  4. Let pairing finish — cellular activates automatically. Once complete, open Settings > Cellular on the watch to confirm the plan appears.
  5. Test by making a call or sending a message with your iPhone out of Bluetooth range.

Setting up standalone mode​

Standalone mode is designed for family members (such as children) who don't have their own iPhone. You manage settings like Screen Time, contacts, and location sharing from your iPhone.

Before you start:

  • Separate Apple Accounts for yourself and the family member using the watch
  • Two-factor authentication enabled on your Apple Account
  • A Family Sharing group that includes the watch user (you must be the organizer or parent/guardian)

Setup steps:

  1. Remove any physical SIMs and turn off any eSIMs on the iPhone you're using for setup (this prevents other carriers from blocking the Set Up Cellular option).

  2. Restart both your iPhone and Apple Watch.

  3. On your iPhone, open the Apple Watch app, select All Watches, select the family member's watch, and select Done.

  4. Select Cellular > Set Up Cellular.

    note

    The watch must be signed in with a different iCloud account than your iPhone for this option to appear.

  5. Complete the installation in the pop-up. Your watch line will be active when done.

  6. On the watch, go to Settings > Cellular to confirm the plan shows as active.

Switching to a new Apple Watch​

  1. Sign in and go to My Lines, then select your wearable line.
  2. Select Change Watch under Line Management.
  3. Enter the IMEI of your new watch and select Confirm.
  4. Select Authorize Transfer.
