Raise your hand if this comes as unexpected news to you. Crickets. Alright, we know Google isn't really revealing the most secret of secrets with its newest "Cellular support comes to Android Wear" announcement, but it is clarifying a few things we didn't know about how LTE would work on our smartwatches.
In his post, Peter Ludwig, Product Manager for Android Wear, explains that cellular connectivity on Wear will allow you to leave your phone behind and use your smartwatch on the go. However, it doesn't seem like you'll be able to completely forego the phone, à la Samsung Gear S2, because both phone and watch will need to be turned on and connected to a network for Wear to do its thing. Essentially, it looks like LTE won't make the watch completely independent, it will just release it from the Bluetooth or WiFi restriction, so you can use it away from your phone and outside of known WiFi networks. The watch automatically switches to LTE and everything should work as if your phone was nearby: calls, messages, apps, fitness tracking, Google Now and Google searches, etc.
Google's announcement post focuses on the LG Watch Urbane 2nd Edition. Suspiciously, it stays mum about speaker support coming to existing Android Wear devices like the Huawei Watch and the ASUS ZenWatch 2. Technically, you should be able to use those to make calls and get Google answers without having your phone nearby or holding it to your ear. But we still don't have any confirmation, so we're left waiting again.
