Tesla is working on a smart phone that uses satellite communications. Will supposedly have a solar panel on the back so it can charge anywhere during the day, and if no cellular connection is available, it will directly communicate via the Starlink satellites. Not in widespread use until they get more version2 Starlink satellites in space - these can communicate to mobile devices without a cumbersome antenna dish.
Going to need some non-economical, subsidized, polar orbit satellites to provide coverage for high latitudes.
