Ah yes I see that. Will be curious if it stays as just a dead zone service. Interesting the wireless providers would sign on for this which could ultimately challenge them in the future.
It probably isn't physically possible to do phone with Starlink high speed service. The dedicated antenna would be better than existing 4G/5G but small size would be a problem. Also, the Starlink antennas depend on having good view of the size.
Finally, the market is tiny of people wandering in the wilderness who want high-speed data. Starlink competes with itself since its service can be used for remote camps; there are rumors of a smaller antenna. Starlink even makes it easier to setup wilderness cell towers and microcells at house.
