Using the Communication Extension to Send Text Messages
The Communication extension allows you to send text messages directly to a mobile phone number. This is helpful to directly reach people with no or only limited Internet connectivity or users outside your organization.
Install the Communication Extension
To install the extension, go to the Extensions menu, open the 
Marketplace (Updates and Extensions), and search for Communication Extension. For more detail, see Adding extensions.
Get API Access Tokens
The extension requires an account with a 3rd party API provided by vonage (https://www.vonage.com/communications-apis/messages/). Once you have created an account, you can log in and directly see the API key and secret tokens.
Please note, that for testing purposes you can send only messages to the phone number you initially provided when creating your account. When you add additional credits, you can send messages to arbitrary numbers. The actual prices can vary by country, but on average a message costs a few cents.

Sending a Text Message
Once the connection is set up, it can be used in combination with the Send Text Message (SMS) operator to send a text message from a process.
This operator takes a mobile phone number and a text message as input parameters. On execution it will to send the message to the provided number using the credentials from the connection object. You can also specify a sender name to identify yourself.
