The Galaxy Watch 4 series comes in two models; the Galaxy Watch 4 Classic which succeeds the Galaxy Watch 3 and the Galaxy Watch 4 which succeeds the Galaxy Watch Active 2. I have used it all and I can only say it keeps getting better. The respective models come in two sizes; 44mm and 40mm for the Galaxy Watch 4 and 46mm and 42mm for the Galaxy Watch 4 Classic. Each of these sizes is available in Bluetooth only and LTE models. As a result of the different sizes and models, consumers have to make double decisions with respect to size and model. The first thing you should know is that the LTE and Bluetooth models have the same design and features. The only difference between these two is that the LTE model is a standalone smartwatch and is priced higher than the Bluetooth model. So, in this guide, we’re comparing the difference between the Galaxy Watch 4 Classic Bluetooth vs LTE model to help you decide which of these models is right for you.
Also note that the 42mm and 46mm sizes have the same features and design except that the 46mm is bigger, priced higher, and has a longer battery.

Samsung Galaxy Watch 4 Classic Bluetooth vs LTE – The Difference
The Bluetooth and LTE models of the Galaxy Watch 4 Classic have the same design and the features are also the same. The only difference between these two is that the LTE model comes with an eSIM that enables cellular connectivity on the watch. This makes it a standalone smartwatch that can make and receive calls independent of a smartphone and the LTE model is also priced higher than the Bluetooth model.
Meanwhile, the Bluetooth model can also make and receive calls, but it will require your phone to be nearby to perform these functions.
In other words, the LTE model is a more comprehensive smartwatch than the Bluetooth model.
The presence of a cellular network on the Galaxy Watch 4 Classic, will not only allow you to make and receive calls, but it will also give you access to the internet which is required for you to download watch faces, stream music, install apps, and access Google maps. The LTE model with cellular can perform all these functions independent of your smartphone, but the Bluetooth model will require your phone to perform these same functions.
Although, the Galaxy Watch 4 Classic has wifi and Bluetooth as means of connecting to other devices. And with a working WiFi network connected, you can stream music, download apps, and download watch faces on the Bluetooth model independent of your phone.
