Samsung Galaxy Watch 4 Bluetooth vs LTE Prices -The Bluetooth model is cheaper
Starting with the Prices, the LTE model is priced higher as a result of its standalone capabilities. The 40mm Bluetooth model costs $249.99, while the 44mm Bluetooth model costs $279.99.
On the other hand, the 40mm LTE model costs $299.99, while the 44mm LTE model costs $329.99. So, you’ll have to pay extra more to get the LTE model.
Cellular Connectivity/Standalone Capabilities – The LTE model is a standalone smartwatch
The main difference between the LTE and Bluetooth models of the Galaxy Watch 4 is the presence of an eSIM in the LTE model. This enables standalone capabilities like being able to make and receive calls independent of a smartphone. It can also receive messages, and you can install apps directly on the watch independent of a smartphone.
You can do all these with the Bluetooth model, but your phone must be nearby to make and receive calls and receive messages or to install apps.
It’s about the added freedom that comes with the LTE model. So, if you’re looking for a smartwatch that allows you to receive messages, make and receive calls without carrying your phone along, then the LTE model will suffice.
Galaxy Watch 4 LTE Carriers – Which Carriers are Supported? – A total of four models serve the globeBefore you decide to purchase the LTE model of the Galaxy Watch 4, you want to be sure that you’re buying the right model for your region.

It’s the same battery capacity for both models. However, when you turn on LTE on the LTE model, the battery life will be shorter. Otherwise, you get up to 2 days of battery life with the 44mm size or just over a day of battery life with the 40mm size. This is quite abysmal but still better than what you get with the Apple Watch Series 7 which only averages about a day of battery life. Nonetheless, I recommended some tips that can help you get a little longer battery life from the Galaxy Watch 4
