Floor plan single-family house 130 sqm, hillside plot, 2 floors

I plan to replace my 300L tank next year with a 200 x 60 x 60 one. Almost exclusively blue Congo tetras will go in there. :) I still need to save a bit.

I am currently having problems with our telecommunications house connection.
Fiber optic cable was installed into the house, but the provider is not making progress with further expansion in the area, and it is currently uncertain when it can be activated.
I already commissioned Telekom in February of this year to additionally and as a precaution lay a copper cable to the house.
But even here, despite multiple inquiries, Telekom is hardly making any effort to dig up the street and lay a cable.
I am now forced to order a mobile home spot for the time being, mainly because I work from home and am dependent on an internet connection.
Mobile home spots are significantly more expensive than comparable DSL providers, but we have no other choice.
My question about this:
Has anyone of you had similar problems or experienced this before? Isn't there a supply obligation on the part of telecommunications providers?
Or is a mobile data connection sufficient to be exempt from the supply obligation?!

I am now forced to order a mobile hotspot for the time being, if only because I work from home and absolutely depend on an internet connection. Mobile hotspots are significantly more expensive than comparable DSL providers, but we have no other choice.

Does that mean a broadcast vehicle is then parked in your street (nowadays of course in car-trailer format) because your house cannot currently be connected terrestrially?

Hehe, there are also cell towers in the underdeveloped Westpfalz. Anyone else have any ideas?

Unfortunately, I cannot contribute anything, but I would still like to ask a question: With whom did you build in the Westpfalz?

Hehe, there are also cell towers in the underdeveloped West Palatinate.

You mentioned a mobile hotspot. If the West Palatinate has mobile cell towers , it must be rather well developed. What I meant (and what I also imagine under the mentioned mobile hotspot) are, as I said, OB vans in mini format, i.e. access points of terrestrial cell towers housed in a kind of catering trailer that can be parked by the roadside.
