Billing
Unless otherwise agreed, SMS text message rates apply at $0.01 / Text message sent. While you can send a text to dozens or hundreds of persons in your organization, text rates apply at the rate of $0.01 / Person / Text sent.
Automated SMS Texts
Another feature of the SMS text communication mechanism is to have texts sent to employees when certain events occur. The primary events are Daily & Weekly Hours Thresholds. The use in this is to make sure that the user receives an alert as soon as possible should their hours be reaching a preset level whereby the employees should take action - such as log out or check in with the manager. See Setting and Managing Notifications for more information.
