O2

O2 Germany (operated by Telefónica Germany) is one of the three major mobile network operators in Germany, offering a wide range of mobile, home internet, and business connectivity solutions. With a focus on affordable pricing and flexible tariffs, O2 is particularly popular among younger users, freelancers, and expats.

For newcomers to Germany, O2 offers both prepaid SIM cards (no fixed contract required) and monthly plans. Prepaid options are especially useful when you first arrive and haven’t yet completed your Anmeldung (address registration), as they can be purchased and activated with just a passport. O2’s Free and O2 My Handy tariff families offer a wide range of data allowances and optional EU roaming add-ons.

O2 shops are found in most major cities and shopping centres across Germany, and online purchases and account management are fully supported in German. The network coverage is strong in urban areas, with continued investment in 5G expansion.

O2 Business serves self-employed individuals and SMEs with tailored mobile and connectivity solutions, making it a versatile provider for expat entrepreneurs. Customer service is available via phone, live chat, and in-store across Germany.
