To see an alert on your Windows computer when a text arrives on your business number, check your notification settings in the Teams app.

1. In Teams, select the three dots at the top of the window, then Settings.
   
2. Select Notifications and activity.
   
3. Make sure notifications are not muted.
   
4. Scroll down to the apps section and expand the SMS app.
5. Check that:
   • the toggle is On,
   • SMS Received is set to Show in Activity and banner, and
   • Other Activities is set to Show in Activity and banner.
     

Your organization may have given the SMS app a different name. Look for the name and icon your administrator gave you.
