Take the hit for once and do the right thing.
If this is your provider, give them the message.

In any case, multiplexing wouldn't stop the tracking, and they might as well figure out just as much about you.
Worked for a year then woke up day to have no phone number anymore and a completely rude support rep.
So, no. This isn't an option.
... maybe I should check whether they're doing this stuff too. My experience with them makes me believe "absolutely" (they're annoying to deal with, but hey, they're following the law).
This is the opinion of every German I've ever met, but as an outsider who formed their opinion before hearing the public's opinion, O2 gives me consistently better signal than my work phone where my boss decided to go with Telekom for some reason I have yet to ask after (but, knowing germans, I have a suspicion). This is in NRW mostly (both cities and forested area), can't remember if it was different in Frankfurt or Stuttgart, so at least not noticeably worse I guess.
The fairly recent (like, after people formed this opinion) merger with E+ probably helped, if I remember this provider's history correctly.
