Nonsense they are an MVNO they don’t really control their network they and their provider still track you (even if only for signaling purposes) and the SIM card can’t really block anything they just route all your data through TOR which is actually a pretty poor thing to do from an OpSec perspective.
Also with mobile phones data only or not all mobile phones must be able to call emergency services and provide their location data if you are so paranoid that you elect to use TOR for everything you might considering never touching a mobile phone again.
