We want to give each member of the nominees the greatest possible flexibility to work on their final solution. Nevertheless, the final results should meet the following core guideline:


Web3 for telecommunication - creating a human centered internet: deliver a tangible prototype or solution (at least an MVP) customized to “Telekom”/T-Mobile USA during the “development phase”.


At the end of the development phase, you will pitch your ideas in front of a grand jury in Bonn (Germany). You will need to prepare a pitch deck in the preparation phase (template will be provided). You will also need to demonstrate your tangible solution.

A minimum viable product (MVP) is a solution with basic functionality. It is a simple yet complete product. It is devoid of many advanced features and only focuses on the core of the idea. The distinctive feature of a minimum viable product is quality. Many people mistakenly think that an MVP is a raw version of a solution. But an MVP implies a simple product, and at the same time, it must be of high quality to interest the target audience. This includes easy navigation, beautiful design, and an intuitive interface.
During the development phase, we would like you to deliver a tangible research or design concept that you can present during the final pitch & award ceremony. Typical examples of a prototype could be:
  • Design prototype: deliver something tangible, like a film, collage, click-dummy, 3D Model, etc.
  • Technical prototype: you should deliver a functional and tangible technical prototype of your idea.


Yes, it will be possible to save your application, edit and delete it until the end of the respective submission phase. Once the submission deadline arrives, your application will be automatically submitted, and it will be locked from editing.

The applications will be accepted from October 31, 2022 until January 20, 2023, 23:59 CEST. The selected ideas will be notified via email by February 3, 2023 and admitted to the development phase.

In the development phase from February 6, 2023 until May 7, 2023, 23:59 CEST we are expecting you to work on the development of a prototype or solution.

The pitch session and award ceremony will be held on May 23-24, 2023 in Bonn, Germany. Please mark in your calendar the dates from May 22, 2023 until May 24, 2023. These are the dates you should plan to be in Bonn for organizational reasons (e.g., installing your solution, technical readiness, dry run of the pitch session).

The evaluation and selection process of the T Challenge is designed to create an open, accountable, multi-step selection process based solely on the merit of the submitted ideas. All submissions shall receive the same opportunity.

Each eligible submitted idea shall be evaluated by expert evaluators from DTAG, TMUS or selected partners. The main selection criteria are a clearly expressed concept, which in the view of the evaluators holds the most promise to have significant impact on the customer experience and has the best fit with Deutsche Telekom’s and T-Mobile USA’s strategic goals.

After the idea submission phase, a qualification jury will assign all idea proposals to one of the three “top award categories”. Per “top award category” up to 6 teams will be nominated and enter the “development phase”. During the development phase, each team should focus on further developing/adapting the idea to be able to present a tangible solution during the final pitch- and demo day. A grand jury will select one winner for each “top award category”. Additionally, we would like to honor the best performing teams with our three “special awards”.

All nominees in the development phase (up to 18 teams) are eligible to be (additionally) awarded with any of these special awards. This means that you could win in all special award categories in addition to your top award nomination.
