Google has updated its Android Wear OS for smartwatches with cellular support, so wearables on the platform will be able to stay connected with a SIM card, even when the phones they pair with arenβt nearby.
The first smartwatch to ship with a SIM slot along with support for cellular connectivity is the LG Watch Urbane 2nd Edition, which was announced last month and will be available in the US and South Korea this month.

The new feature will allow your smartwatch to automatically switch to a cellular connection when youβre out of range of your phoneβs Bluetooth or trusted Wi-Fi network. If both devices are online, youβll be able to receive notifications and run apps as usual, no matter how far apart your phone and watch are.
Thatβll come in handy when you want to go out for a run and leave your phone at home, without missing alerts. Plus, youβll be able to make and receive calls on your watch, if youβre into having conversations with your wrist.
While this puts Android Wear ahead of Appleβs WatchOS in terms of functionality for the time being, it may not be the killer feature every potential smartwatch buyer is looking for. Cellular connectivity means an additional strain on your watchβs tiny battery, so you might find yourself charging your timepiece more than usual because of it.
