Apple Watch Series 3 features built-in cellular and more

Apple Watch Series 3 (GPS + Cellular) features a full LTE and UMTS cellular radio that switches seamlessly to cellular when it is away from iPhone. The watch shares the same number as iPhone so there’s no need to provide an additional number to family, friends or colleagues; and to help get customers started, participating carriers are also offering special introductory cellular plans at launch. Customers have the ability to make cellular calls directly with Apple Watch Series 3 (GPS + Cellular) and, when paired with AirPods, enjoy a seamless and fully wireless experience. Apple also pioneered an industry-first antenna design that uses the display itself as both a transmitting and receiving element for LTE and UMTS, while introducing a built-in eSIM that is over one-hundredth the size of a traditional SIM card, making over-the-air activation possible without compromising space.2
