O2 is the fastest growing mobile operator in Slovakia. Since the beginning of its operation, it has brought revolutionary solutions, open communication and fairness to all customers without distinction. With a simple product portfolio, it systematically changes the rules of mobile communication. We were the first to bring a truly unlimited program for calls and SMS to Slovakia, the first to introduce a commercial test operation of the LTE network, or to offer mobile payments via NFC technology. We consistently enjoy the highest customer satisfaction among all operators.
