You’re standing at Zurich main station. Your train is due to arrive in two minutes. Just then, your smartphone rings. It’s an important customer. You see the call in the Teams app, press “Accept” – and then it happens. “Hello? Can you hear me? Hello?” The connection crackles. The voice sounds like a robot. The image freezes and the conversation is gone. Why is this happening? You have an expensive smartphone and a modern subscription. The problem is not with your phone. The problem lies in the way we work on the go. Many companies that want to connect their smartphones to Microsoft Teams rely exclusively on the app. And they often try desperately to squeeze professional business telephony through a narrow data channel. The Microsoft Teams apps are great for chats, files, and short messages. But they are often simply not enough for reliable “hybrid work telephony” and stable real-time communication in the field. There is a better solution. It puts an end to “app frustration.” It combines the stability of the GSM network with the intelligence of Microsoft Teams. And it’s called Easy Mobile Connect. Connect your smartphone to Microsoft Teams now!
To understand the added value of Easy Mobile Connect, we need to get a little technical. When you make a call using the classic Teams app on your cell phone, you are using VoIP (Voice over IP). Your voice is broken down into small data packets and sent over the mobile Internet (4G/5G). This works wonderfully in the office on Wi-Fi.
But outside, the mobile internet is a “shared medium.” You share the bandwidth with hundreds of commuters who are streaming Netflix or checking social media. When the cell is full, your voice packets are slowed down. The result: “robot voice,” delays (latency), and dropped calls.
Then there’s the usability factor: If you want to call someone, you first have to unlock your phone. Then find the Teams app. Wait for it to load. Search for the contact. That takes time. And if your phone’s power-saving mode puts the app to sleep in the background, it sometimes doesn’t even ring. In short, apps are often a makeshift solution for pure telephony. Not a permanent solution.
How would you like to be able to use your business cell phone just like your personal one? Without searching for apps. Without data dependency. Simply by using the normal green phone button. That’s exactly what Easy Mobile Connect from TwinCap First makes possible.
We use modern eSIM technology (in partnership with Tango Networks) to connect your smartphone to Microsoft Teams. This turns your cell phone into a real extension of your phone system.
The genius of it: you no longer need the Teams app to make calls. You use the normal phone function of your iPhone or Android device.
In the past, we had to juggle: “You can reach me at the office at -10 or on my cell phone at 079…” That’s a thing of the past. Easy Mobile Connect finally implements the single phone number, also known as the One Number Concept.
Whether you’re sitting in the office, working from home, or on the highway, you always communicate under one identity. When you call from your mobile, the customer sees your landline number. This creates trust and professionalism.
There is one important prerequisite: For this seamless integration to work, your Teams telephony (direct routing) must already be running via TwinCap First. Why is that? Because we are technically building the bridge between the mobile network and your Teams tenant. We can only do this if we also have ‘access’ to the lines. So if you already use us for your phone calls, there’s nothing standing in the way of the traffic light.
Easy Mobile Connect solves specific problems in everyday work for a wide range of professions:
Whether salespeople, chauffeurs, or tradespeople: anyone sitting in a car or truck doesn’t have a free hand for apps. With Easy Mobile Connect, you can make calls using your car’s hands-free system. The connection is stable, even when you’re driving on country roads where 5G is still unheard of. You’re reachable – professionally and securely.
This isn’t about convenience, it’s about response time. One problem with the Teams app is often that the ringtone is too quiet or cannot be changed. Since Easy Mobile Connect uses the native phone function, you can set your own loud ringtone. If an emergency call comes in at night, you’ll wake up. Guaranteed. It just works.
Similar to being on call: You won’t hear a soft “Teams bling” on a construction site. You need a robust ring tone and vibration. Since you use your cell phone “as normal,” you benefit from all the hardware features of your device without being restricted by an app.
Do you work in a regulated industry (finance, law) where calls must be logged or recorded? When employees make private calls, you have a “blind spot.” Since Easy Mobile Connect technically routes every call through the Teams server, your compliance guidelines also apply to mobile devices. Seamlessly.
Many employees do not want to install company apps on their private cell phones and reject monitoring mobile device management (MDM). Easy Mobile Connect is the most elegant solution here. The business eSIM is installed via a QR code, and you’re ready to go. As soon as you finish work, you simply switch off the eSIM, and it is deleted when you leave the company. This means your private data remains untouched and private at all times.
You may be wondering, “Sounds good, but is it complicated to set up?” No. The process is radically simplified. Since we at TwinCap First have direct access to the routing (our Teams Direct Routing solution is a prerequisite), we activate the “Microsoft SIP Gateway” for you in the background.
Your onboarding process is as follows:
To install, you need the Extend app from Tango Networks in your Microsoft Teams (this can be installed by IT or by yourself):
No IT technician needs to touch your cell phone. No hours of training. Anyone who knows how to use a phone can use Easy Mobile Connect.
It’s 2026. “Modern work” or “hybrid work telephony” doesn’t mean we have to put up with poor connections just because we’re not sitting at our desks. And it also doesn’t mean that we have to give customers our private cell phone numbers just to stay connected.
Easy Mobile Connect gives you the quality of a landline and the freedom of mobile communications.
Are you ready to bring your Teams telephony into 2026 and connect your smartphone to Microsoft Teams? Already using our Teams telephony? Then you’re ready to go. Let’s talk – and you’ll be able to test the offer free of charge for 30 days in no time.
