Create a user ID for every smartphone number
Even if you don’t manage the AT&T account for your household, you’ll need a user ID associated with your smartphone number in order to sync your phone with your wearable. Example: If you have a family of five and each person has a NumberSync capable wearable, then each person will need a user ID associated with their smartphone number.
