A Marketing Cloud admin wants to configure a new keyword for an upcoming SMS campaign.

When encountering an issue with the availability of a desired SMS keyword such as "CELEBRATION":

Keyword Unavailability: The keyword may already be in use within another business unit within the organization, making it unavailable for use in the current context.

Solution: Check the keyword usage across all business units and, if possible, coordinate to see if the keyword can be shared or if an alternative keyword would be suitable.
