    Those devices may have a fingerprint. A lot devices can be uniquely identified. Here is an example that I read a long time ago so it might be wrong or I might not remember correctly.

    Your phone has a gyroscope, compass and accelerometer. Those tools are not perfect. Your compass does not point straight north, so it has to be calibrated. That calibration produces like a 6digits offset (0.739842). If you look at all the calibration numbers for a device you get a number that is basically unique for each phone. So even if you used different networks, they can still know that you used a device that you had previously used or associated with you account somehow. That’s why brave is an important step in what I said.
