Can I make calls on a 4G smartwatch?
Yes – if your smartwatch has LTE or eSIM with an active plan, you can make and receive calls without your phone. Apple Watch 11 GPS + Cellular and Samsung Galaxy Watch 8 LTE both support true standalone calling. Without LTE, most watches need your paired phone nearby or online via Wi-Fi. When Apple Watch is connected to a Wi-Fi network, you can still do the following (even if your iPhone is turned off): Get apps in the App Store. Send messages.
