Our brands

Our best-known own brand is our core brand O2. With it, we inspire, support, and empower our customers to shape their digital lives freely and confidently. O2's products and services are available across all channels for consumers and business customers. In addition to our core brand, our secondary and partner brands offer products for individual needs.
Our Blau brand, for example, is characterized by a particularly simple, clear product portfolio with an excellent price/performance ratio. With brands such as AY YILDIZ, we also appeal to ethnic target groups. Through our entire brand portfolio and our strong partners, we as Telefónica Deutschland reach an enormously large number of interested parties and tap into new customer groups.
