This is related to a pretty good example of why eSim fails in practice! You cannot use a Google Fi data sim with an Apple Watch (the cellular version, that is).

This is related to a pretty good example of why eSim fails in practice! You cannot use a Google Fi data sim with an Apple Watch (the cellular version, that is). Since the Apple Watch (Cellular) version uses an eSim, it's tied to explicit network support, and therefore won't work. If it took a normal SIM I could just put my Fi data sim in and be good to go.
