Dimagi provides a set of shared SMS connections for our projects. You can also setup your own private connections.
An overview of SMS connection options can be found here (Gateway Options for SMS Projects).
For each project, you must select a connection that will be used. (For advanced projects, it can also be controlled per recipient phone number).
Set a Project Gateway Connection
Go to the Messaging tab, select Dashboard and then select SMS Connectivity in the left menu.
Choose a gateway as the default. If needed, add another gateway (HTTP or Android).
Add Another Connection
If you'd like to use a different connection for your project, you can add it using the "Add Another Gateway" option at the bottom of the page.
Choose Telerivet (Android) to setup an Android phone based connection (Setup an Android SMS Gateway).
