Apple Watch's GPS + Cellular variant, first introduced with Series 3, connects to your carrier's SIM automatically and lets the watch send texts, take calls, get notifications, and stream music independently of a paired iPhone. The standard GPS model still needs a nearby iPhone for most of these functions, while the cellular version works over 4G or 5G on its own.
