My plan advertises "up to 50 Mbit/s" on a 4G connection. I was getting less than 1 Mbit/s a lot of the time. Websites and videos would not load properly.

I downloaded the app of the german ministry that allows you to take speed tests and file a complaint. After multiple weeks of measuring connection speeds on the cellular network, I was able to file a complaint.

What did the provider do? Did they put your IMEI onto some list of other customers that complained, where all of you get better network prioritization?

I'm genuinely curious.
