1&1

1&1 is one of Germany’s largest telecommunications and internet service providers, offering mobile plans, home broadband, and digital services to millions of customers across the country. As part of the United Internet Group, 1&1 has built a reputation for competitive pricing and reliable network coverage.

For expats setting up in Germany, 1&1 offers a range of mobile tariffs — both SIM-only and with smartphone options — covering the O2 and (increasingly) 1&1’s own new network. Home internet packages include DSL, fibre (FTTH), and cable connections, making 1&1 a practical one-stop shop for connectivity needs when moving into a new apartment.

1&1’s website and customer service are primarily in German, though the sign-up process for standard packages is straightforward. An Anmeldung (German address registration) is typically required to take out a contract, and a SCHUFA check may be conducted for longer-term agreements.

For those who prefer a digital-first experience, 1&1 offers online account management, self-service troubleshooting, and a comprehensive help centre. Customer support is available by phone and online chat during business hours.
