⁶Emergency SOS requires a cellular connection or Wi-Fi calling via an Apple Watch or a nearby iPhone’s internet connection. You can use Apple Watch Cellular models to make emergency calls in many locations where cellular service is available. Some cellular networks may not support emergency calling from Apple Watch if it is not activated, incompatible with a specific network, not configured for use on a particular network, not set up for cellular service, or if the network does not support IMS emergency calling.

⁸Apple conducted testing in July–August 2026 using preproduction Apple Watch Series 12 (GPS) and Apple Watch Series 12 (GPS + Cellular) units paired with iPhones. All devices were tested with preproduction software, Apple Watch magnetic fast charger–USB-C cable (model A3277), and Apple’s 20W USB-C power adapter (model A2305). Charging time varies with power source, region, settings, battery charge, usage, and environmental factors. Actual results may vary.
