Do you have CT Text on your account?

In order to send/receive messages, you will need to have CT Text setup on your account.  Webex Go and Teams Mobile do not inherently offer SMS capabilities.  You will need to have an SMS service, with a compliant campaign registered, to be able to send/receive SMS messages.  

CT Text is CallTower's messaging platform. This platform not only enables SMS capabilities for your eSIM, CallTower can also optionally activate an integration to Webex/Teams so all messages sent from your native messaging application can sync with your Webex/Teams inboxes. 

If issues persist

If you have followed the steps in your welcome email, completed the setup guide, reviewed these steps, and are still having issues- please reach out to CallTower Support.
