GÖNN is a mobile tariff and deals app developed by Telekom Deutschland GmbH. It offers a unique mobile tariff with exclusive deals for users under 28 years old. The app provides 10 GB of data per month on the Telekom 5G network, with the option to expand at any time. It also includes an Allnet Flat for SMS and phone calls, EU-wide roaming, and support for both SIM and eSIM cards.

One of the standout features of GÖNN is the inclusion of three dayflats per month. Users can enjoy worry-free mobile data while attending festivals, lounging at the beach, or exploring cities. GÖNN allows users to decide when they need and use their dayflats.

Additionally, GÖNN offers a referral program called "Friends with GÖNNefits." Users can refer up to five friends and receive an additional dayflat for unlimited surfing every month for a whole year, both for themselves and their referred friends.

The app also provides monthly exclusive deals that are unique, varied, and without hidden costs. Users can avail up to three deals within 12 months, and there are no exclusions based on tariff type.

GÖNN supports eSIM, which is a built-in digital SIM card in new phones. This allows users to surf on Telekom's 5G network without the need for a physical SIM card. The eSIM feature also enables users to use an additional tariff, such as a corporate contract, alongside their regular SIM card.

To use GÖNN, users must be between 18 and 27 years old. The app can only be booked digitally through the app itself. For more information and answers to frequently asked questions, users can visit the official GÖNN website.

Overall, GÖNN is a mobile tariff and deals app that offers an attractive package for young users. With its generous data allowance, exclusive deals, and convenient eSIM support, GÖNN provides a compelling option for those looking for more than just a boring tariff.
