Add NumberSync

Sync and use your watch

Start using your iPhone’s wireless number on your watch¹ in a few steps. (While your watch can only sync to one iPhone at a time, an iPhone can sync to up to three watches.)

Place your watch and iPhone next to each other.
Open the Watch app on your iPhone.
Follow the prompts to pair and select Myself to set up your watch.
Continue to follow the prompts to activate and use AT&T NumberSync® on your watch.

In addition to making calls, you can also get notices and listen to your smartphone’s voicemail on the watch.

Want device-specific instructions? Go to Device Support, select your device, and enter NumberSync in the search field. If you’re still having trouble, you can get help with NumberSync issues.

Connect to our network

Apple Watch works in three different modes:

Bluetooth®: The watch uses Bluetooth to communicate with your iPhone. When you make or receive a call on the watch, your iPhone makes or receives the call but sends it to the watch. The iPhone also shares its data with the watch using Bluetooth. Turning on airplane mode or turning off Bluetooth doesn’t stop this connection.
Wi-Fi®: When outside Bluetooth range, the watch connects to known Wi-Fi networks for data and to make and receive calls
Cellular: If the watch has a wireless plan and isn’t near Bluetooth or Wi-Fi, it will use our network for calls and data.

FYI: You can get text messages and iMessages on your watch. For text messages, make sure your iPhone is turned on and connected to our network or Wi-Fi. For iMessages, your phone doesn’t have to be turned on to receive messages on the watch. Just make sure iMessage is enabled.

Eliminar NumberSync

Open Settings on your iPhone.
Choose Cellular, then Pick your SIM, and then Calls on other devices.
Toggle off Calls on other devices.

Note: Turning Wi-Fi Calling off disables it for all devices on your account.

Unsync watch with a wireless plan using your watch

Open the Watch app on your iPhone.
Tab Cellular and then the info icon.
Elige Manage AT&T account.
Tap Unsync watch.

FYI: Unsyncing your watch doesn’t cancel the wireless plan associated with it.

Unsync watch with a wireless plan using att.com

Go to Manage NumberSync devices.
Choose your device and then Unsync watch.
Follow the prompts to confirm removal, then restart your iPhone and watch.

Heads up: Removing NumberSync doesn't cancel your phone plan. It just means your watch won't be able to use our wireless network, and we'll still bill you for monthly service. Para cancelar tu plan, contáctanos.

Unsync watch to resync to another iPhone

Open the Watch app on your iPhone.
Tap My Watch and then All Watches.
Select the info icon for the watch you want to unsync.
Tap Unpair Apple Watch and then Keep Plan.
Wait for the process to finish before you sync your new iPhone.

Good to know: Unsyncing your watch from an iPhone returns the watch to its factory state.
