Hey @Thalhammer
Hologram is working hard to shed more light on the state of Cat-M1/NB-IoT networks in Germany and the rest of the world. As you are aware Cat-M1/NB-IoT is still relatively new and globally the roaming scenarios aren’t fully standardized yet, so we have very few confirmed Cat-M1/NB-IoT networks that we have access to and Germany is not one of those countries.
Having said that, there is a lot happening in the global Cat-M1/NB-IoT sphere which should give us more insight into how everything will shake out in a few months time.
Best,
Maiky
