I remember being on a tour in Romania in 2019 on a bus and in the middle of a forest in Transylvania and a colleague called that they have some issues at work and if I could please look into it. Then I just tethered my LTE reception (sometimes it dropped to 3G but was still usable) to my laptop, SSHed in and fixed the issues for them. In Germany, even being on a quite populated beach some 500 meters away from the promenade of a popular vacation city (Heringsdorf) is a hit or miss in regards to a usable mobile reception not even talking about LTE (this is on O2 Deutschland, in August 2020). There are many parts of Germany, that are more or less white spots in regards to a usable mobile data connection. I mean, sometimes my phone would just use the polish signal from Świnoujście even though Heringsdorf is about 10 km from the border.
