Roaming

To enable O₂ Telefónica customers to make mobile calls and surf the Internet in around 200 countries, we work more than 500 mobile network operators (roaming partners) worldwide. As different as the countries are, we have the goal to offer our end-customer always highest quality at the best possible costs. To this end, O₂ Telefónica enters so-called "roaming agreements" with selected network operators

in around 200 countries, which ensure technical connectivity and billing. These roaming agreements are two-sided: Customers of O₂ Telefónica brands can make calls or surf the Internet in the foreign partner network. Conversely, customers of the respective roaming partner can also use the O₂ Telefónica network when they are in Germany.
