Using this system, the researchers uncovered vulnerabilities in real-world mobile networks, including billing flaws that allow free internet access, weaknesses in IPv6 firewalls, and hidden communication between SIM cards and their home networks. They also demonstrate how users can be tracked via signal characteristics during roaming voice calls.
