Mein o2

Manage your o2 mobile contract with the award-winning Mein o2 app — your gateway to account control, consumption tracking, and billing anytime, anywhere.

Whether you're on a prepaid plan, monthly contract, or My Handy device payment agreement, Mein o2 puts all essential services in one place. Access your account details, monitor usage, handle billing, and update your information without visiting a store or calling customer support.

For contract customers, stay on top of your spending with real-time data volume tracking — both at home and internationally. View consumption for calls and SMS outside your flat rates using the convenient home widget. Review detailed tariff information, browse available options, and upgrade your plan directly from your phone. Download itemized bills whenever you need them, manage SIM and contract services including eSIM activation and number portability, and submit network checks or fault reports instantly. Mein o2 rewards loyalty too — unlock new customer benefits every month through the Priority program.

Prepaid users gain immediate visibility into their remaining data, minutes, and SMS units. Check your current credit balance and top up instantly, switch tariffs on demand, or add extra options to match your needs. Update your account details with just a few taps, and run live network diagnostics whenever connectivity feels off.

My Handy customers enjoy a dedicated view of their device contract, access their digital invoice anytime, track their installment plan in detail, and benefit from early payment options.

The app delivers live network checks, allowing you to report faults directly to o2 support without leaving your home. Everything from invoice viewing to service management is streamlined for mobile convenience — no more logging into a web browser or waiting for postal bills.

Mein o2 is built exclusively for o2 private customers in Germany. Business accounts should download the dedicated o2 Business App instead. Note that Alice Mobile connections and third-party provider accounts are not supported. You'll need an active account at o2online.de to get started.
