Alas, this will do nothing to thwart tower triangulation techniques.
Even your "privacy-friendly dumb cellular" is announcing its unique ID
to all towers within range at regular intervals, and what with increased
tower density these days it's all too easy to derive your location.
True, it won't have the same degree of fidelity as even consumer-grade
GPS, but it's a lot more information than I'm comfortable handing over.

So I use a pay-as-you-go sim, paid for with cash.  I also don't sweat it
when I forget the thing or the battery runs out.  After all, it
increases my personal privacy.
