SMS Working

I am trying to figure out how to get SMS working. I have enabled SMS on my phone number. That phone number now shows "disable sms" as an option in the phone numbers listing. I sent that phone number an SMS from another phone and I do not see the message come through in Teams.

I tried following the setup which says to enable enterprise voice but it is not shown where the how-to describes: https://learn.microsoft.com/en-us/microsoftteams/sms-overview
