knowing a phone model is not the same as seeing and ID card with all the Details, that makes a huge difference for the individual’s privacy…
most ISP operators I have seen don’t give a damn about your privacy, if you’re their friend, just ask… give them a phone number and they’ll give you all the details ( Face, Home Address… Etc )… In other countries like Iraq, you can buy that information for a very very low price…
removing the ID card from the equation provides huge privacy benefits for people from these sick fucks… If you’re worried about being found by the authorities… Avoid SIM cards alltogether
