In {{#fas:cog}} (SETTINGS) ->GUEST MANAGEMENT->AUTO ACTIONS you can set up manual and automated Auto Actions to send SMS messages to guests.
We can set a short alphanumeric code (max 11 char) that the guest sees as the sender of the message for a fee. This could be your trading name for example. The code will be set for the masteraccount (the account paying for the SMS) and apply to all subaccounts.
