There are a couple reasons why a user in Workflow Builder might not have SMS fully enabled for their account or extension. Check to see which of these two issues may be affecting you and take the appropriate action.
You do not have a phone/device or phone number assigned to you
All SMS messages must be sent from a phone number you have rights to. For most, this is a phone number that has been assigned to them. You can verify that you have a number via our Admin Console. Follow these steps.
- Log into the Admin Console
- Click the "Settings" tab.
- Expand the "Phones & Numbers" section.
- Check for one of the following:
- There is a "Primary Number" assigned to you.
- Under the "Numbers" tab, make sure a number is assigned to you.
If you do not have a number assigned to you, contact your account administrator to have one assigned to you.

SMS feature is not enabled for your number/extension
If you have a phone number, that phone number needs to be enabled for SMS. This check is best done via a RingCentral API, but in almost all circumstances a number is not enabled for SMS because your organization has not successfully completed a TCR registration. This is a step required by all carriers to help combat fraud and comply with industry regulations.
To resolve this problem, please register your company and how you are using SMS via the Admin Console.
