Set up NumberSync for wearables

Choose your messaging app

If you don’t already have an AT&T cloud inbox, we’ll create one for you as part of the NumberSync^SM setup. The inbox syncs messages between your smartphone and smartwatch.

For the best NumberSync experience, choose AT&T Messages Backup & Sync as the default messaging app on your smartphone. Here’s how:

1. Go to Messages.
2. Tap More, then Settings, and finally AT&T Messages Backup & Sync.
3. Select Turn it on if it’s not already enabled. We’ll send you a confirmation text.

Good to know: To sync a wearable with a smartphone number on a different account, you have to enter the AT&T user ID and password for that account. After you enter the Sync Code, you’ll be asked to sign in with the smartphone number's AT&T user ID to complete the NumberSync setup.
