Pretty Good Phone Privacy

https://raghavan.usc.edu/papers/pgpp-arxiv20.pdf describes a new MVNO “backend stack” that requires no carrier changes, but shields MVNO customers from the carrier. Republic should take a look at this idea to see if it can increase customer privacy.

Pretty big ask based on an academic paper tested only in a lab using 3 devices in a traditional MVNO environment without Republic’s hybrid calling.
