The service is not cheap, requires eSIM devices, has no phone number thus no calls or SMS/MMS, uses AT&T for the backend virtual carrier.
Sounds like a list of cons but at the same time some pros. No carrier tracking, randomized IMSI, relaying (multi-hop) traffic (VPN really).
Figure if one wanted to start off fresh they could get a Pixel, install CalyxOS, Graphene, or some other unGoogled OS, the PGPP service, and something like JMP.chat (to have a number people can call as well as send SMS/MMS) to have what sounds like a pretty good private setup.
For those who like to read debates, discussion, legalities, pros, cons, etc. there is quite the discussion on ycombinator (Hacker News) regarding PGPP and related matters. Quite interesting.
Yeah. I was reading some info about that at the Graphene GitHub regarding that.
It’s like for every upside of something there’s a downside. sigh
In general I prefer to set up a ROM with neither Google nor microG. The day when eSIMs can be used without neither, something like PGPP would seem pretty good.
