After listening to nostr:npub1h8nk2346qezka5cpm8jjh3yl5j88pf4ly2ptu7s6uu55wcfqy0wq36rpev‘s Basics of Bitcoin about hashes, could we not find a way to protect against this by hashing something on the device against the SIM to verify only it could use the SIM without some change process (new phone etc)? This is out of control!
