[Review] I tried using Galaxy Watch4 (LTE) in the new era of smart watch

New OS adopted, and built -in LTE

Galaxy Watch4 is a smartwatch announced in September by Samsung, known in the Android smartphone "Galaxy" series.The product variations are very abundant, there are two products lines, "Galaxy Watch4" and "Galaxy Watch4 Classic" with different appearance, wristbands, etc., each with two display sizes, and two to three more color variations.It is prepared.

The general smart watch has a Bluetooth/Wi-Fi communication function and operates in combination with a smartphone.The smartwatch side has a built -in microphone and speakers to make a call, but since this is based on the telephone function on the smartphone side, the smartphone is turned off or the smartphone is left somewhere and forgetting it.You can't make a phone call in a situation where there is only a smart watch.

Under these circumstances, Galaxy Watch4 has a model with additional mobile communication functions by LTE in addition to Bluetooth/Wi-Fi.In Japan, only au is available among the four major carriers (mobile phone companies), and in order to enable LTE communication, a paid option contract called au mobile phone line and its paid option "Number Sear" is required.is.Please note that even if you prepare only a watch, you can not call it alone.

If you subscribe to the "number share", the same phone number as the mobile phone to be paired will be assigned to the smartwatch side, making it possible to send and incoming the phone with a smartwatch alone.The Apple Watch is already a familiar service, but it has not been used on Android terminals so far.

So, this time, I borrowed the display size 40mm/black of the LTE compatible version of the au LTE.The selling price at the au online shop is 38,764 yen.The smartphone to be paired is Pixel 5 (updated to Andorid 12) sold from au, and is equipped with a physical SIM card from the "Pitat Plan 5G" contract.

Let's talk about the adoption of the new OS.Android ... or rather, Google has been providing a smartwatch OS under the "Wear OS by Google" (formerly the Andorid Wear) brand.However, in May, Samsung announced the integration with the OS "Tizen" that was developed independently.The new "Wear OS Powered by Samsung" was born, and the earliest product that adopted the OS is Galaxy Watch4.

Personally, I have been using Wear OS by Google (and its predecessor OS) smartwatch since 2016.Most recently, we purchased "OPPO Watch" in September 2020, and Wear OS by Google is almost part of life.We are also paying attention to how much change has occurred with the OS new Galaxy Watch4.
