Apple Watch Ultra 3: A closer look at its satellite communications tools

Here is a 184-word summary of the news article: The new Apple Watch Ultra 3 is the second mainstream smartwatch after the Garmin Fenix 8 Pro to support satellite communications. This feature allows users to send messages, share their location, and contact emergency services when cellular connectivity is unavailable. The process of connecting to satellites is similar to the iPhone 14's implementation, requiring the wearer to aim their wrist towards the sky. In addition to satellite connectivity, the Ultra 3 boasts other upgrades like the S10 chip, a larger display, bigger battery, and support for 5G. It also introduces new health features like hypertension notifications and sleep score tracking, which will also come to the Series 11 and older Apple Watch models. The article compares the Ultra 3's satellite capabilities to the upcoming Pixel Watch 4, which uses a different satellite network and has a "check replies" feature. While the Ultra 3's satellite services are initially limited to certain countries, Apple is providing two years of free satellite service with the purchase of the watch.
