Today workforce is more mobile than ever before, employees need a full featured mobile experience that works across networks and devices. To help organizations with the Microsoft is now releasing Teams Phone Mobile in General Available, previously this service was announced as Operator Connect Mobile. To start with it will be available from Rogers in Canada and Telia in Sweden. More partners will release Teams Phone Mobile soon.

My colleagues and I been testing Teams Phone Mobile for a couple of months, and it will be great to see customers starting to use it, there have been many questions from customers that wants to start using Teams Phone Mobile. I really hope that the partners in this program will expand fast so we can see a broad availability of Teams Phone Mobile.

Update (Feb 27th 2023)

Now we have Teams Phone Mobile available in five different countries from Verizon (United States), Rogers Business (Canada), Telekom Deutschland (Germany), Telia (Sweden) and Swisscom (Switzerland).


Users enabled with Teams Phone Mobile will get their mobile phone number assigned to their Teams user account, there is no need for an additional fixed number in Teams anymore. All incoming calls to their mobile phone number will ring on their signed-in Teams Devices and on their mobile phone, Teams mobile app or native dialer.

When you do an outbound call (or inbound) from your mobile native dialer to a colleague or external user in Teams you will be able to uplift the call from your native dialer to your Teams mobile app and start sharing documents and video in Teams. When you uplift a PSTN call from your native dialer to Teams you will be able to use features in Teams like, recording, transcription and easily transfer calls to users in your company directory. With Teams Phone Mobile users will have the same voicemail for both Teams and mobile calls, since you now only have one number.

Incoming calls will only ring on one native dialer, never both as users might experiences in earlier simultaneously ring scenarios. Users will be able to select if incoming calls should ring on Teams mobile app or on native dialer, this can also be controlled with a mobile policy from Teams Admin Center.

In our tests and in conversation with others I think that the most common configuration will be that users select to receive calls in their native dialer on the mobile.

User Experience

When users start their Teams mobile app, they will get a First Run Experience (FRE) pop-up, this will show the phone number that is configured for the user. Without the FRE, there can be issues using Teams Phone Mobile and the solution is to sign out and sign in again or reinstall the mobile app.

First Run Experience shows the phone number assigned to the signed in user.

When a user, in native dialer mode, receives a PSTN call to their mobile number it will ring on all their signed-in Teams applications (computer, desk phones, displays, etc) and on their native dialer on their mobile phone. User can then select to answer on any Teams application or in their mobile native dialer, but it will never ring on the Teams mobile app.

Presence – see that you colleagues are in a call

Presence is an important part of Teams and can (should) be used before calling a user, if you see that your colleague is busy “In a call” you will probably not call them, if it is not super duper important. Now with Teams Phone Mobile, we will be able to see “In a call” for users busy in a native mobile call as well. This presence can also be used by third-party tools like attendant software.

PSTN Calls

In this example we see a call from external PSTN to my test user, it is the same functionality with outbound calls from native dialer.

In the example above we see an incoming PSTN call, that is answered. Then I open the Teams app and get the information that I have an ongoing call and Teams asks if I want to move that call to Teams. The call is then moved to Teams and I can continue the conversation in Teams with the caller. Since the caller was a PSTN caller there are no options to share video or content, but I can use other Teams features like captions and transfer calls.

Teams will ask user in mobile app if they want to move the call from native dialer to Teams app.

PSTN Calls from Teams users

If the caller is a Teams user that dials a Teams call (Teams -> Teams) or a PSTN call (Teams -> PSTN) we will get more capabilities in Teams when we do Uplift of the call.

In this example I get a call from an external Teams user, I select to answer the call on my mobile on the native dialer. When I open the Teams app on the mobile phone Teams see that is a Teams user that called me and can also see that it is Adele that called me. I select to move the call to Teams I can now turn on video, I could also start sharing content in the call since it is now a Teams to Teams call.

Move call to computer

When I have an ongoing PSTN call on my native dialer on my mobile phone I can open any Teams client where I’m signed in and it will ask me if I want to move the call to that device instead.

One use case for that is if I answer an incoming call when I’m not at my desk, but during the call I arrive at my desk and want to start sharing an application from my computer. In this case I can easly move the call from my native dialer to my Teams application om my computer and start sharing my desktop and video.

Call history and missed calls

Call history will be shown in both native dialer and Teams. If you answer a call in Teams it will not be shown as a missed call on your mobile and if you answer the call in the native dialer, it will not be shown as missed in Teams – this is a common issue when using Simultaneous ring with Teams and external mobile phone numbers.

You will see missed calls on both native dialer and in your Teams history so you can select where to call back from.


To get started with Teams Phone Mobile you first need a connection with one of the carriers in the partner program, open Teams Admin Center and open the Operator Connect section and filter on Teams Phone Mobile. You should currently see two carriers in that list, contact them via Teams Admin Center or directly and they will set you up with a subscription.

When you are up and running you will see all your available phone numbers in Teams Admin Center and can start assigning them to users. As you can see in the example below phone numbers from Microsoft Calling Plans, Operator Connect (landline) and Teams Phone Mobile are all listed in the same view and administrated in the same way, easy for administrators.

An additional policy is now available in Teams Admin Center, Mobility policy. This controls where calls should arrive on the mobile device.

All calls will now be shown in PSTN & SMS ‎(‎preview)‎‎ usage report, this includes mobile calls for users activated with Teams Phone Mobile.
