SMS Messaging allows you to send SMS messages from within the portal and/or from your mobile device. You (and your drivers) can explore additional query services for more advanced functions performed from an SMS-enabled device–such as getting a vehicle’s current location, setting landmarks, adding stop notes, and more.
In order to use Messaging, you must have the Messaging permission enabled in the User Access List, the SMS Messaging and SMS/Email items enabled in the Menu Access List (Custom and Dashlet categories). You will only see messages associated with vehicles and/or drivers that are available to you.
Your message cannot exceed 160 characters. If your message exceeds 160 characters, the message is broken down into multiple messages consisting of 153 characters. The total maximum character limit is 918 characters.
