Hi barathr, thanks for joining the discussion! Having had a brief look at your paper and the Usenix slides[0], I've got three questions:
- Given that your Android app is security-critical for its users, are you planning on open-sourcing it in the near future?
- How exactly does your app work on Android? How does it rotate the IMSI? (I don't know a lot about eSIMs but I would have thought a regular app can't easily change the carrier/network settings.)
- As for the relay functionality, I suppose on Android this "simply" sets up a VPN once the network connection is established?
