Why Does Verizon require a Separate Line for an Apple watch when Apple itself says its not needed arent you charging for needless services then
Apple Watch neither needs nor supports using a separate phone number for the watch.
The watch does not have cellular capabilities of its own, so cannot be used for cellular calls or text messages via cellular service unless it is connected to the paired iPhone (but Wi-Fi calling may be available - see below), which must be an iPhone 5 or later, running the latest version of iOS:
The full range of features is available when Apple Watch and iPhone are connected. Whenever possible, the devices will connect via Bluetooth.
You don't necessarily need to have your iPhone on or immediately around you (within arm's reach, for example) for the devices to establish and maintain their Bluetooth connection. Normal Bluetooth range is around 33 feet / 10 meters (this will vary in practice due to wireless interference).
Whenever your watch can't connect to the iPhone, it will attempt, as a fallback, to connect to a known, compatible Wi-Fi network.
When instead connected to Wi-Fi, the watch also still offers a number of features, including receiving and sending messages via iMessage. If your carrier offers Wi-Fi Calling and it is supported on your plan and enabled on your iPhone, you can also use Apple Watch to make calls and (subject to carrier support) send and receive texts.
If your watch is unable to connect either via Bluetooth or Wi-Fi, it again still offers some - although fewer - features.
Features that remain available in each case are detailed here:
That's certainly a wonderful question on the Apple Watches, Josh1012. The Apple Watch Series 3 and newer models are supported on Verizon's cellular network, and the Apple Watch Series 3 is the only one that requires a phone line paired for service. The separate line of service for the watch is partially for clear billing, while it mainly is to supply cellular service to the watch directly, even if the phone is out of Bluetooth range and without Wifi.
