Climber Florian Schattenberg feels right at home on the rock face. Moving between training sessions and real ascents, indoor and outdoor climbing are a central part of his everyday life. It’s a discipline built entirely on routine, meticulous preparation and clear processes. You need to be able to rely on your equipment, your partners and the commitments you make,” Florian says.
Communication is a tool that is often underestimated. When you’re climbing, most communications are simple and direct: a call, a reply and everyone is on the same page.
But what happens when you don’t just need to communicate with your climbing partner – like being able to call for help in an emergency? That’s when reliable mobile coverage becomes a lifeline. Opening the Mobilfunk-Check app has become second nature after a climb to Florian. “It’s not something I think about 24/7, but it’s reassuring to know you can reach someone if you need to,” he explains. It’s not just about convenience – it’s also about safety.
And that is exactly what the Mobilfunk-Messwoche is all about. With the app, assessing mobile network quality is right at your fingertips. The “check network” feature systematically tracks key connection metrics like signal strength, network technology and stability. To protect privacy, all data is collected anonymously – helping build a highly detailed, real-world map of mobile coverage across Germany.
The “speed test” feature measures precise download and upload performance, while latency data shows exactly how quickly the network responds. Results can vary significantly, especially in mountainous terrain or remote climbing areas. Solid rock faces, the distance to the nearest cell tower, and local network traffic can all influence connection quality. That’s why any single test is only ever a snapshot.
Building a reliable, big-picture view takes repeated measurements across different locations and at different times. Together, the data pinpoints exactly where coverage is “rock-solid” and where gaps still remain – creating a real-world roadmap to improve long-term network quality.
Now it’s your turn! Check your network today. The more people who take part, the more accurately we can evaluate network quality.
