What is SMS Opt-In?
SMS Opt-In enables operators to allow community members, visitors, event participants, or other users outside of their organization to subscribe to receive alerts by SMS. These outside users can subscribe to receive alerts by sending a text event code via SMS.
Organization Administrators create event codes, and then share the event code and the short code with users. When a user opts-in by sending an SMS with the event code, they are added to the BlackBerry® AtHoc® management system. Administrators can then target them in alerts.
