Cable Germany & Telekom sensible??

I will start building soon and now the following question arises regarding the house connection.

We are planning with a satellite dish for the TV and want to do internet and phone through Kabel Deutschland.

Would you still have a Telekom line installed in the house in addition? Or is that even necessary?

I don't really want to have anything to do with Telekom anymore, but I also don't want to be dependent on one provider. Would you bite the bullet, have a connection installed and pay for it, which you might never use?

You then become dependent on the KD. The DTAG only lays the cable for you, ultimately you can order elsewhere. It costs €384! I would do it (I have it too). But I don’t have a cable for it, since I want SAT.

I would also have both installed. As "Perlenmann" already says, Telekom only lays the cable. And the excavation is done only once anyway.

In any case, have it installed. What will you do if someday your boss says: Guy, from now on you’ll occasionally work from home, and I’ll pay for your home internet connection (like my boss currently does)? And this internet connection has to be from Telekom due to contracts. Then you’re stuck with the short end of the stick and might have to redo everything.

Of course, your boss can hardly force you to do this, but I like to use home office as an opportunity to avoid being stuck in rush hour traffic sometimes.

Or another scenario, you have performance problems with Kabel Deutschland. What then? Or they kick you out of the contract because your child causes a monthly traffic of 100 gigabytes.
(I already received this threat from KabelBW because I distributed my own Linux distribution and had massive traffic peaks over 3 months.)

So I’d invest the 400 €, or have a branch office set up at your place for free. Just in case.

Have you already inquired at Kabel Deutschland? In our new development area, no cable was laid, or rather, we were not even given an offer, but the laying was refused.

Thank you first of all for the answers.

I actually see it that way too. At this point, one probably shouldn't cut costs.

@Wastl: No, I haven't inquired by phone yet but only did a availability check over the internet. According to this, it should work, but I heard yesterday that our future neighbors apparently had problems with the Telekom connection. Apparently, Telekom did not connect them. But I'll ask about that.
