Key Takeaways

  • Upgrading to a cellular Apple Watch comes with added cost, but it allows you to leave your iPhone behind while continuing to make phone calls and stream music.
  • Both the cellular and GPS-only Apple Watch models have the same hardware, but the cellular version unlocks Family Setup and exclusive watch faces.
  • Battery life is roughly 18 hours for both models, but heavily relying on a cellular connection will deplete the battery faster.
