How do I add family members to AT&T Secure Family?
If you have an AT&T wireless account, you can add family members when you first set up Secure Family. Or, add them later from the app by tapping the plus (+) icon at the top and following the prompts. You can only add numbers that are on your AT&T account.
If you have an AT&T PREPAID account or U.S. wireless service with another provider, select a contact from your contact list. Or, enter a U.S. wireless phone number. Secure Family will invite them to install the companion app so you can pair with them.
