Currently we have to do all of our SMS marketing outside of maropost because we don't have the ability to send SMS messages as part of journeys. As I think most businesses send bulk SMS messages in their auto-responders in some form or another, I think this is an important request that would not only help us, but help everybody else as well!
One of our upcoming strategic initiatives is the project called "Unique Identifier." This project unifies contact records across all messaging channels including email, SMS, and mobile apps. A unified contact record is the foundation to cross-channel messaging -- which you'll start to see available within Journeys.
