Additional chat-related features and issues within Microsoft Teams for business
Hi Albert,
My name is Didi. I'm happy to help you today.
I'm afraid the ability to use the SMS feature is currently only available in the 'Teams personal' and 'Teams small business versions' but not in the business version.
I invite you to upvote this requested feature or leave a comment at the following feedback portal links:
