Smartwatches have become much more useful over the years thanks to faster chips, improved health/fitness tracking, and more capable apps. The first is LTE connectivity, which allows you to use your smartwatch separately from your smartphone. However, not all smartwatches support LTE connectivity.
Google and Samsung smartwatches are available in LTE, but many other Android smartwatches are only available in Bluetooth/Wi-Fi models. Is LTE connectivity a must for smartwatches?
Perhaps the biggest argument for LTE on smartwatches is that it can be used without tethering to your smartphone. This means you can make calls, send texts, and stream music from some apps without your phone nearby. Useful if you misplace it. This could also be useful in certain emergencies, especially with the growing number of smartwatches with features like fall detection.
A recent update to Google Maps also makes it possible to navigate on Wear OS smartwatches without having to piggyback on a connected smartphone.
On the other hand, many people cannot let go of their smartphones for long periods of time. Never leave home without checking your keys, wallet and phone. This fact alone might not be worth using an LTE-equipped smartwatch. Especially since that connection usually comes with a monthly extra charge.
Additionally, many apps are adapted for non-LTE smartwatches. Top streaming services like YouTube Music and Spotify have dedicated his Wear OS apps that allow users to download tracks and playlists for offline listening. Samsung smartwatches such as the Galaxy Watch 5 can also store music files from your smartphone. Many fitness apps can track routes without an LTE connection thanks to built-in GPS.

Galaxy Watch 5 is a smartwatch that has it all. Great design, impressive health and fitness tracking, decent battery life, and amazing performance. Additionally, for a small extra charge, you can get an LTE model that is completely disconnected from your phone.
