This guide shows how end users can send and receive SMS and MMS messages within Microsoft Teams, using two connector options: the SMS Connector App and the new Unified Connector App. This guide outlines how message presentation differs between the two apps

Connector Apps Overview

Microsoft Teams supports two connector apps for SMS and MMS messaging: the legacy SMS Connector App and the new Unified Connector App. Both provide access to full SMS application interface as an embedded tab, but they differ in presenting the SMS from within the Microsoft Teams client.

SMS Connector App

Operates through Teams and Channels
- Each hosted phone number is linked to a Team
- Each channel is linked to the other SMS party.
Includes the SMS full interface as an embedded tab within the app for direct access to SMS conversations aside from teams and channels.

Unified Connector App (new)

Operates through Chats
- Displays SMS and MMS messages as Chats in the Microsoft Teams chat interface.
- Provides a streamlined, private messaging experience aligned with typical Teams chat interactions.
Includes the same SMS full interface as an embedded tab within the app for direct access to SMS conversations aside from Teams chat.
