A:Answer With the GPS+ Cellular the phone functions work even if you don't have your iPhone nearby. A "GPS + Cellular" Apple Watch, or simply a "cellular Apple Watch," is a model that allows you to make calls, send texts, and use data on your watch even when your iPhone is not nearby, as it has the capability to connect directly to a cellular network through a dedicated cellular plan added to your existing phone service; essentially giving your watch its own phone number to function independently.
