The Federal Network Agency (Bundesnetzagentur) has implemented new regulatory norms designed to transform the declaratory rights of subscribers into a functional legal mechanism. Mobile users now possess a legitimate instrument to renegotiate contract terms in cases where a provider systematically fails to deliver the stated quality of connection. This pertains to the possibility of a proportionate reduction in monthly fees or even the unilateral cancellation of the contract.
To apply these norms correctly, the legal context must be understood. Although the concept of a right to a discount was legally enshrined in the Telecommunications Act as early as 2021, the lack of a clear measurement methodology rendered it virtually inapplicable in practice. Providers frequently cited the technical characteristics of radio wave propagation and external factors. The agency’s new clarifications establish rigid criteria under which a client’s claim is considered justified.
When Mobile Service Fees Can Be Reduced
The grounds for a lawful claim for compensation are the proven fact that the actual data transfer speed regularly and significantly deviates from the parameters guaranteed by the contract. The regulator emphasised: “A single failure is insufficient to lodge a claim. The violation must be systemic in nature and recorded using officially approved software.”
A critical aspect is the transparency of recording violations. Unlike previous periods when the evidence base was formed arbitrarily, the only recognised argument now is the data from a measurement protocol. This removes subjective assessments from the parties and moves the dispute into the realm of specific figures and technical indicators.
Conditions That Must Be Met
The evidence collection procedure requires a high degree of discipline and strict adherence to the algorithm from the user. For a claim to gain legal force, the subscriber is obliged to perform the following actions:
- Carry out 30 control measurements via the specialised app “Breitbandmessung Nachweisverfahren Mobilfunk”;
- Distribute the measurement sessions evenly over 5 calendar days (6 measurements per day);
- Conduct testing at any location within Germany, confirming the mobile nature of the service.
The right to financial compensation or contract termination arises if, for at least three out of the five days, the established minimum speed was not reached even once. Furthermore, threshold values are differentiated depending on the type of terrain where the measurement is taken:
- Rural regions: actual speed must be at least 10% of the maximum promised;
- Semi-urban areas: the threshold is 15%;
- Cities: the minimum permissible level is defined at 25%.
What This Means for Clients
If the measurement protocols confirm the operator’s failure to meet its obligations, the client gains the legal right to choose one of two paths. The first is a proportionate reduction of the monthly bill. The second is the early termination of the contract without paying penalties.
However, experts point out a significant nuance: the methodology for calculating the specific discount amount is not prescribed by law. This means the subscriber must enter into individual negotiations with the service provider. In the absence of a consensus, the matter may be referred to the courts, requiring a willingness to invest additional time.
Criticism from Consumer Rights Advocates
Representatives of public consumer protection organisations are sceptical about the effectiveness of the measures, calling them a “compromise solution.” Felix Flosbach from the North Rhine-Westphalia Consumer Advice Centre noted the methodological vulnerability of the rules. According to him, if only three out of thirty tests fall slightly above the critical threshold, the right to compensation will be lost, even if the other twenty-seven results demonstrate catastrophically poor connection quality.
Lina Ehrig from the Federation of German Consumer Organisations adds to this criticism by pointing out the lack of transparent mechanisms for calculating discounts. Providers retain the right to independently determine the discount size, which often leads to opaque calculations and causes further dissatisfaction among clients.
Experience in Fixed-Line Communication and the State of Mobile Networks
Practical experience with similar norms in the field of home broadband internet shows that the bureaucratic complexity of the process often deters users. Many discontinue the series of measurements midway due to the high labour intensity of the procedure. Major market players, such as Deutsche Telekom, confirm that the actual number of formally processed claims remains extremely low compared to the total number of complaints regarding connectivity.
Nevertheless, the general technical background in Germany demonstrates positive dynamics. Multi-billion dollar investments in infrastructure have resulted in a significant increase in coverage by the end of 2025. The Telekom network provides 4G coverage across 92.5% of the territory and 5G across 87.9%. Vodafone and O2 Telefónica also show high results, covering approximately 90% of the country with the 4G standard. Thus, while the mechanisms for protecting rights have become more accessible, the vast majority of subscribers already have access to high-quality connectivity that meets the technological standards of the current year.
