We are a telecommunications operator that promotes simplicity, transparency and fairness not only in mobile communication, but is also actively involved in important social issues. With our product portfolio, we are trying to systematically change the usual rules of mobile communication. Thanks to this, we have been here for 15 years and currently provide our services to more than 2.3 million customers. We are among the most popular employers and through our Fair Foundation O2 we are also involved in the field of social responsibility.
