Best Smartwatches With Sim Card (LTE)

With the advent of wearable tech, more smartwatches have been entering the market every year. What was previously thought of as a gimmick now has serious markets in the space. Our phones, which were perhaps mandatory for us to bring everywhere, have seemingly given up their uses in favor of sleeker, more portable smartwatches that also have LTE functionality.

Therefore, if you are an avid traveler, don’t like bringing your phone everywhere, or are keen on using a cellular connection on your smartwatch, we’ve jotted down the best smartwatches that have LTE functionality for you right here.

Benefits of a Smartwatch with a Sim Card (LTE)

Let’s get one misconception out of the way from the get-go. You cannot use an LTE smartwatch as your sole cellular device. However, there are still a few distinct advantages you gain from opting for a smartwatch that has an LTE configuration.

  • Portability: Having the convenience of keeping your smartphone at home and still being able to listen to music or attend calls is quite useful!
  • Travel Partner: You might not always be able to whip out your phone when you are cycling or traveling. With your LTE-activated watch, you can still check for directions while not needing to reach for your pocket.
  • Better Cellular: If you have an older phone, chances are that your newer smartwatch might end up receiving better signals than your handset. In these cases, a watch can turn out to be extremely useful as you get that much-needed data.

The primary disadvantage of owning an LTE Smartwatch is excessive battery consumption which can lead to your device not being used for an entire day in most cases. Thankfully, you can turn your cellular off and bring your battery life back!

Now that we’ve gone through the benefits of owning a Smartwatch with a Sim Card, we’ll now be noting down some of our best picks. Instead of opting for a traditional list, we’re going to be mentioning the best smartwatch for each particular category.

People complained that Apple Watches have a short battery life. Apple had a solution, they created a new model – Apple Watch Series 8 Ultra, with improved battery life, among other things. Thanks, Apple. Thank you also for not naming it Apple Watch Series 8 Pro…

The Ultra watch is larger than all its predecessors. 49mm(41-45mm before).It’s not just bigger. It’s also more durable, brighter, and has an improved battery life of up to 36 hours. It is also water resistant to 100 meters. Not only can you swim with it now, but you can do some diving. It even has a built-in depth gauge.

It has a digital crown and a side button. The crown button now has deeper ridges, and the side button extends out from the body. It’s easier to press it now, even if you are wearing gloves.

Overall, it’s a great watch, offers a lot of functionalities, and is great for everyday people, great for hikers, great for athletes, etc.

Best LTE Samsung Watch
2. Samsung Galaxy Watch 5 Pro
  • Size: 44-45mm
  • OS: Wear OS
  • Water Resistance: IP68, water resistant up to 5-feet for up to 30 minutes
  • Additional Features: Sleep Monitor, Blood Pressure Monitor, Activity Tracker, Daily Workout Memory, Elevation Tracker
  • Battery Life: ~80 hours
  • Connectivity: WiFi, Bluetooth, GPS, NFC, LTE
  • Compatibility: Android
  • Great Battery Life
  • Titanium Body
  • Great Health Functions
  • Fast Charging
  • Bulky
  • Some Features Not Working(Have To Wait For Software Update)
  • Rotating Bezel Is Removed

Just like Apple, Samsung also released an updated version of their SmartWatch, but they named it the Pro watch instead of Ultra. Samsung is working hard to surpass Apple, working together with Google in terms of software updates, and they managed to create a beautiful smartwatch with a lot of functionalities. A watch that s made for harsher conditions.

If you’re looking for an LTE Android smartwatch, you won’t find any better.

Samsung has improved its battery life on the Pro model. It has Sapphire crystal glass and titanium body, improved sleep tracking, a new temperature sensor, body temperature(there are some errors with this function), and enhanced Bluetooth and wi-fi connectivity.

Considering the fact that it’s a Pro model, I would like it to be more rugged, but it is what it is; overall, I believe it’s the best Android watch you can get as of now. They also have removed the rotating hardware bezel.

It’s definitely a nice update if you’re using an older Samsung smartwatch.

3. Apple Watch Series 8
  • Size: 41-45mm
  • OS: WatchOS
  • Water Resistance: Water resistance rating – 50 meters, IP6X(dust resistant)
  • Additional Features: Activity Tracker, Heart Rate Monitor, Sleep Monitor, Blood Oxygen
  • Battery Life: 18 hours
  • Connectivity: LTE, WiFi, Bluetooth, GPS, NFC
  • Compatibility: Apple iPhone
  • Security Features
  • Reusable Bands
  • Ecosystem
  • Fitness Tracking
  • Same Aesthetic
  • Poor Battery Life
  • Compatible only with iPhone

If you already have an Apple Watch Series 7, buying the Apple Watch Series 8 doesn’t really make sense. If you are upgrading from an older version, you will get additional screen real estate, better speakers, faster processing, additional health features, ECG, etc.

Don’t get us wrong, it’s a great watch, but compared to it’s predecessors, the improvements aren’t that great, to consider buying a new watch.

They updated Ovulation Tracker for women, emergancy crash deetection and now it has a better processor, which makes it a bit faster.

Overall, it’s a great watch for fitness & activity tracking, for navigation, for contactless payments, phone calls, emergencies, media controling, home controling, etc.

4. Samsung Galaxy Watch 5
  • Size: 40-45mm
  • OS: Wear OS
  • Water Resistance: IP68, water resistant up to 5-feet for up to 30 minutes
  • Additional Features: Sleep Monitor, Blood Pressure Monitor, Activity Tracker, Daily Workout Memory, Elevation Tracker
  • Battery Life: ~50 hours
  • Connectivity: WiFi, Bluetooth, GPS, NFC, LTE
  • Compatibility: Android
  • Fast Charging
  • Great Performance
  • Google Assistant
  • Body Temperature
  • Bottom Curve
  • WearOS 3
  • Samsung Locked Features(Limited to Samsung Smartphone users)
  • Some Features Still Not Working(Needs Update)

Samsung Galaxy Watch 5 has made some improvements incomparison to it’s predecesor Galaxy Watch 4. More ergonomic design, Google Assistant, faster snappier processor and wearOS 3.

If you’re in the market for LTE smartwatch and you have an Android phone, this is the best option you will find. Should you buy it if you already have Galaxy Watch 4? Well I wouldn’t be too hasty in this situation. There are some imporvements, but they aren’t major. The biggest advantage if you’re updating from an older model at least for me – fast charging.

It’s great for casual users and for people into fitness. Samsung has already created five different versions of this watch and keeps improving and let’s hope they don’t stop. Overall, I believe this currently is the best Android watch you can get besides their Pro model.

Best Security Oriented LTE Smartwatch
5. Garmin Forerunner 945 LTE
  • Size: 44 mm variant
  • OS: Proprietary
  • Water Resistance: IP6X
  • Additional Features: Heart Rate Sensor, Pedometer
  • Battery Life: 35 hours
  • Connectivity: WiFi, Bluetooth, LTE
  • Compatibility: iOS, Android
  • Rugged Design
  • Has An Immense Array Of Security Features
  • Full With Features
  • No Touchscreen
  • Expensive
  • Blood Oxygen Isn’t 100% Accurate

Clunky but functional would be the best way to describe the Garmin Forerunner 945 LTE. While not the most good-looking or the most powerful, the Forerunner 945 LTE never claimed to be either. With the lack of a touchscreen, conventional navigation methods are thrown right out of the window.

Instead, you’ll have to rely on the side buttons loitered around either end of the watch to navigate across each menu. As you might’ve already guessed, the lack of a touchscreen reduces the number of options the watch has when it comes to applications. The inclusion of proprietary software does indeed bring in applications like Spotify, but that is pretty much it.

In terms of security, though, this is where the Forerunner shines. You’ll be able to use Garmin’s LiveTrack, which allows your friends to see your location in real-time using their high-accuracy GPS sensor present within. 

Besides that, though, their most exciting feature is the inclusion of Assistance Plus. This not only sends your location to Emergency Services but also uses Garmin’s IECC network, the same one used by individuals who are caught in a pinch in extreme situations, be it stranded at sea or lost in a mountain. 

All in all, if you have a knack for keeping yourself secure or just can’t stay out of trouble, the Garmin Forerunner 945 LTE is a no-brainer.

Do All Garmin smartwatches work with iPhones?

6. Samsung Galaxy Watch Active 2
  • Size: 40-44mm
  • OS: Tizen OS
  • Water Resistance: Swimproof (5 ATM)
  • Additional Features: ECG, Heart Rate Sensor, Sleep Tracking
  • Battery Life: ~48 hours
  • Connectivity: WiFi, Bluetooth, GPS, NFC, LTE
  • Compatibility: Android & iPhone(with limited features)
  • Stellar Price
  • Works with iPhones
  • Modern, Stylish Design
  • ECG Features Not Available In All Countries
  • Tizen OS is Lackluster

If you are on a budget, the Samsung Galaxy Watch Active is the way to go. Featuring a battery life of about 2-3 days, the introduction of FDA improved ECG, and a sleek design that still looks timeless, you’ll be able to squeeze in a lot out of this tiny package.

Considered an honorable predecessor to the new and improved Galaxy Watch 3, the Active 2 still runs Samsung’s proprietary Tizen OS. While you can’t expect the same plethora of applications to be greeting the Active 2 anytime soon, you still have access to the basics like Spotify, Pandora, and even a third-party application that lets you watch YouTube directly on the watch.

Besides that though, the watch offers great fitness tracking, integrates well with Samsung Health, and works as a great companion. In terms of LTE usage, the watch is quite solid. You can perform everything from navigating throughout the city or listening to your favorite beats with your phone miles away. 

We’re big fans of the Galaxy Active 2’s overall design language. It comes in a variety of colors, and while it does not have the same variety of bands as, say, an Apple Watch, it does get the job done. 

One caveat that we’ve noticed with the LTE version of this smartphone is that the battery will drain considerably faster. While this isn’t a deal-breaker, you’ll need to vary in how much you use your device. Otherwise, it might not even last the entire day in some instances.

Apple Budget
7. Apple Watch Series SE 2022
  • Size: 44-44mm
  • OS: WatchOS
  • Water Resistance: Water resistance rating – 50 meters
  • Additional Features: Sleep Monitor, Activity Tracker, Voice Control, GPS, Heart Rate Monitor
  • Battery Life: 18 hours
  • Connectivity: LTE, WiFi, Bluetooth, GPS, NFC
  • Compatibility: Apple iPhone
  • Great Price
  • Upgraded Processor
  • Lightweight
  • No Always-On Display
  • No ECG 
  • No SpO2

If you’ve been an avid Apple fan, you’d know that the SE lineup was always reserved for something special. While features are generally cut around from an Apple device once it gets the SE tag, the Apple Watch, for this instance, was truly something different.

Honing the same design the SE featured a slightly older processor (the S5 from the Watch Series 5) alongside limited color options and the same brushed aluminum finish. Besides that though, the watch operated and functioned exactly like a flagship. 

While the lack of an Always-On Display, especially on an AMOLED might be a drawback for some of you, it ends up saving you a ton of battery life. Speaking of, the cellular connection on this device is great, and the battery life does end up lasting through the entire day, even with moderate to heavy use. While you can’t expect anything more out of the watch in terms of battery, you can expect Apple to be providing a few years of software support.

Besides that, though, there’s not much to complain about the Apple Watch Series SE. It is functional, durable, works with your iPhone, and gets the job done, be it seeing notifications, replying to texts, making calls, or calling an Uber. All in all, the Series SE is an excellent choice if you aren’t in the mood for spending a pretty buck on getting the latest and greatest and can make do with the great price-to-performance ratio that the Series SE provides. 

Best Battery Life
8. TicWatch Pro 4G LTE
  • Size: 44mm
  • OS: Proprietary
  • Water Resistance: IP68
  • Additional Features: Heart Rate Sensor, GPS, Pedometer
  • Battery Life: 2-5 days (if you adjust settings) By turning off AMOLED display you can get it to last 30 days
  • Connectivity: WiFi, Bluetooth, GPS, NFC, LTE
  • Compatibility: Android & iPhone
  • Google Assistant
  • Durable Design
  • Great Battery Life
  • iOS & Android Compatibility
  • Bulky
  • A Bit Slow
  • A Bit Outdated

Alright, we get it. Not everyone’s in the mood to sacrifice battery life for a cellular connection. However, with this pick, you will still have to make sacrifices in terms of the overall quality and functionalities of the device.

The primary feature which makes the TicWatch Pro 4G / LTE so attractive is the introduction of a unique dual-layer display that helps save battery life allowing for the watch to last up to 30 days if used in a certain manner. However, from our observation, even regular LTE usage yielded us 5-6 days which is much better than all the other devices mentioned in the list.

However, as we mentioned earlier, there are still a few tradeoffs that you’ll have to make do with if you want to have such stellar battery life on your wrist with a cellular connection onboard. Firstly, the TicWatch Pro 4G / LTE might feel like a glorified pager in some cases.

Don’t get us wrong, it does have all your basic utilities from being able to track your health, counting your steps, and displaying your notifications. But, that’s pretty much where all the list stops. Don’t expect advanced sleep tracking, onboard applications, or anything that demands more processing power as the Snapdragon Wear 2100 present in the device is sluggish at best and unresponsive at the worst.

However, the TicWatch does make up for its downfalls in some other avenues. For example, you’ll be greeted with a great microphone and an integrated Google Assistant (take notes Samsung!) that let you make and receive calls with relative ease.

All in all, while not the best smartwatch out there, if your primary purpose is to have a smartwatch that has a great battery, is able to perform all the basic utilities most require from a smartwatch while still coming from a reputable brand with passable design, the TicWatch Pro 4G / LTE is a great pick.

9. Fossil Gen 5 LTE
  • Size: 44mm
  • OS: Proprietary
  • Water Resistance: 3ATM
  • Additional Features: Heart Rate Sensor, Pedometer
  • Battery Life: 24 hours
  • Connectivity: LTE, WiFi, Bluetooth, GPS, NFC
  • Compatibility: Apple iPhone, Android
  • Compatibility with iPhone & Android
  • Aesthetically Pleasing Design
  • Beautiful Display
  • Future Update Not Guaranteed
  • A Bit Sluggish 

Fossil has been making great watches for a long while now, and their headway into the smartwatch space has them taking their design language and combining it with tech. While their earlier iterations felt like a hit-or-miss, the Gen 5 LTE is truly an all-rounder.

Don’t get us wrong, the Gen 6 improves on this watch in almost every single way. However, it still does not have an LTE version. However, with that said, the watch runs Google’s Watch OS and therefore has access to hundreds of different applications that work great.

What we’re more impressed with, though, is the seamless LTE connectivity and the Stainless Steel case enveloping the AMOLED display. With a passable Snapdragon Wear 3100 inside, you’ll be able to chug through most tasks with relative ease. 

Fossil offers tons of amazing straps right on their website allowing you to mix and match, having you create the look you desire. While the straps are on the pricier end, we assume that’s what you pay for investing in the Fossil brand! 

Verdict: Which LTE SmartWatch Is The Best?

To be honest, it all comes down to preference. Most of these watches have the same amazing functions, give or take, but Smartwatches are accessories. You have to pick the one you really like. I’m talking visually.

I personally believe Apple Watch Series 8 Ultra is #1 LTE Smartwatch. The #2 I would give to Samsung Galaxy Watch 5 Pro

As long as it has a cellular connection(LTE) you will be able to:

  • Make calls without a phone
  • Go for a run without a phone and listen to Spotify
  • Receive text messages when your phone is left at home

You get the point. For me, it’s simple – I like to count my daily steps. I like to go for a run, but I don’t like taking my phone with me. Especially in summer when it’s crazy hot. I wear a t-shirt, shorts and running shoes, there’s no room for a phone, but I’ve no problem wearing a watch and AirPods, it just makes running more enjoyable. Honestly, that’s the only reason why I even considered the LTE smartwatch.

Since I run this blog, people often ask me to explain what’s the difference between LTE and a normal smartwatch, and this is what I say:

LTE smartwatch is like a proxy. It works as an intermediary between you and your phone.


Do I Need To Pay For My Smartwatch’s LTE ConnectIon?

In most cases, you will need to pay for your smartwatch’s LTE connection. However, cell providers, especially in the U.S. offer special discounts and deals if you already have a phone on contract with them. But, if you don’t have that ease, the watch will operate just like a regular phone in terms of data consumption.

Does an LTE Smartwatch Have Worse Battery Life?

While an LTE smartwatch does not inherently have a component that passively saps away battery life, it does lead your battery to die faster if you have LTE on constantly. Therefore, we recommend selectively turning the option off and not keeping it turned on constantly. 

Can I Make Calls On My LTE Smartwatch?

Yes, you can make calls on your LTE Smartwatch and even receive texts. However, your phone number remains the same as your actual smartphone. You cannot have a dedicated number just for your smartwatch. In fact, your smartwatch will always act as an extension to your smartwatch.

Is LTE Smartwatch Supported In Roaming?

Depending on your phone’s carrier and what sim you have installed, your smartwatch should also be able to work just fine when you are traveling abroad. However, your mileage may vary depending on the local provider and what their regulations and policies are.

I bought my first smartwatch in 2018 and have been wearing one ever since. It might get frustrating at times to receive 100 notifications a day. That's why we need to know how to make the best of them and how to use them to improve our daily lives, not the other way around. I write about the newest smartwatches, I create top picks, and I write helpful guides and simply explain complicated things.
