The Inbound SMS activity lets you download and process text messages from an external account.
The first tab of the Inbound SMS activity lets you enter the routing parameters for SMS messages and enter the script to be executed on receiving each message. The second tab lets you assign a schedule to the activity, and the third tab defines the expiration conditions of the activity.
SMS routing: Select the external account to be used for SMS recovery. External accounts are configured via the Administration > Platform > External accounts node of the tree.
The Script, Schedule and Expiry tabs are detailed in Inbound Emails.
