Tango Extend for Microsoft Teams
Add a Tango Extend eSIM to any mobile phone and use the green button to make business calls from your Microsoft Teams number.

"Now with native mobile integration via Tango Extend, even those users who are never at a desk can maximize their communications efficiency with Teams on any mobile phone."

Teams native mobile calling, without the Teams app
Most attempts to bring Microsoft Teams to mobile rely on the Teams mobile app — which means an extra app to launch, dependence on data connectivity, battery drain, and a learning curve for users. For frontline and field teams, that combination usually means the app is ignored and business calls fall back to personal numbers.
Tango Extend takes a different route. As a Microsoft Operator Connect partner, we provision Teams Phone numbers directly onto a business eSIM. Calls to and from that number run on the cellular voice channel through the phone's native dialer — yet remain a Teams call end-to-end, with Teams identity, Teams routing, Teams recording, and Teams analytics intact.
For IT teams, that means no SBC, no Direct Routing infrastructure, and no separate mobile carrier contracts. For users, it means business mobile calling that simply works — exactly like dialling any other number, with no app to open.
