Top 10 LTE Smart Watches 2021 | 4G/5G Smartwatches with call feature for Android and iOS

 

LTE connectivity (cellular connectivity) is an important premium feature of a smartwatch that helps with keeping your smartphone totally aside. You would want to use this feature during outdoor sports activities and while doing household chores and house cleaning, and also in situations where you don’t want to carry your smartphone and still not miss any call or message even if you are out of Bluetooth or Wi-Fi range from your smartphone. Check out the Top LTE Smart Watches. 

Well, LTE comes at a much higher price compared to the same watch non-LTE version. Also, some smartwatches such as Fossil Gen 5 LTE and Mobvoi TicWatch Pro 4G/LTE (check out Mobvoi TicWatch Pro 3 review) only support Verizon. So you would want to do your due diligence before picking one that suits your needs.

We did extensive research on all the smartwatches available in the market today and picked the Top LTE Smart Watches 2021 that support LTE/cellular connectivity.

You can track as many as 40 physical activities, and of these 7 can be tracked automatically. The built-in GPS can help you get accurate activity readings and incident tracking. The sleep tracking and heart rate tracking of the smartwatch are pretty good. The strong LTE connectivity allows you to use your smartwatch as a smartphone.

The price of the smartwatch is a little on the higher side, but the features are as great as Apple Watch 6.

Calls, notifications, Maps, Music, health tracking, etc seamlessly work with iOS and you have tons of apps that are compatible with Watch OS (Apple Watch 6) and iOS (iPhone). Google’s Wear OS is lightyears behind Apple’s Watch OS, vastly due to Google’s negligence of Wear OS. All leading music streaming services such as Spotify and Pandora perfectly sync with the Apple Watch 6. 

The Apple Watch 6 comes with some amazing fitness features along with an accurate and powerful blood oxygen monitor. The ECG app detects your heart rhythm and is pretty accurate. Tracking workouts like running, swimming, and cycling is easy, detailed, and accurate with Apple Watch 6. You can take a dip into the pool up to 50 meters deep.

The upgraded/renewed Galaxy Watch Active 2 comes with FDA-cleared health features such as ECG monitoring.

  • Fitness features
  • Accurate heart rate monitoring
  • Notifications

Pros
  • Best for the price

Cons
  • Lack of always-on display

Apple Watch Top LTE Smart Watches have always been a key player and a leading contender in the smartwatch market. The Apple Watch 3, initially released with Watch OS 4.0, is easily upgradable to the latest Watch OS 7.0. You do have LTE connectivity and all the fitness features you get in Apple Watch SE. The only major difference between the old Apple Watch 3 and the new Watch SE is storage capacity: the former has 16 GB and the latter has 32 GB. For me, 16 GB works pretty well. Other minor differences would include fall detection and chipset (Watch 3 uses Apple S3). Also, similar to Apple Watch SE, you would not get the ECG monitor, SpO2 tracking, and always-on display.

The sound quality of the speaker is good. As for the fitness features, you can get information related to the number of calories burnt, resting and average heart rate, distance, and speed of the run, among others. If you are considering the latest Apple Watch SE, we would ask you to consider Apple Watch 3 since it comes with similar features and a very affordable price.
