Yes, you can! With the Koll app, you can call any of the more than seven billion mobile phones around the world. The call topic and your contact information are always shown to the receiver, making calling more open and transparent.
Does the receiver need to install the Koll app?
No, they don’t. The receiver sees a Koll call just like a normal phone call, but it also shows the caller’s contact details and the reason for the call.
In which countries is the Koll app available?
The Koll app (which the caller needs to make calls) can currently be downloaded in the following countries:
The Baltic countries
The Nordic countries
Germany
The United Kingdom (UK)
You can download the app in these countries, but once it’s installed, you can use it anywhere in the world.
