  • Communication to the Kids Watch is only allowed between the allowed Parents, Guardians, or Friends. Contact types can only be managed by the Admin, from the Companion Application. Although the Watch has a connection to the T-Mobile network, only the contacts on the approved list can communicate with the Watch. The Watch does not support iMessaging or group messaging.

If the child responds, they will only respond to the approved contact in an individual thread, and no one else in the group message will get their response.
