Do you own a smartwatch? How about a smartphone? If your answer was ‘yes’ to both of these questions, I wonder – doesn’t it annoy you to carry both devices around? I know it does me, which is why a standalone smartwatch with SIM card support should be the obvious choice – if making phone calls from your wrist sounds cool, you may have watched too many TV series in the 1980s. But it does sound cool.

Sure, from a technological point of view, there is no way a smartwatch can stack up to a high-tech smartphone, especially if you consider the screen and camera. However, the mobility and reduced size offered by smartwatches will most likely come in handy. Sending and receiving calls and SMS messages on the go will turn out to be a practical decision, aside from looking all cool while doing so.

Smartwatches are very powerful devices today, packing dual-core processors and over 1GB of RAM. They’re faster than ever and they’re able to run increasingly technical tasks, so why not handle calls and messages without a phone too?

Due to a rise in the popularity of standalone smartwatches, we’ve come up with a short list comprising nothing but the best smartwatches that use SIM cards. But before we get into the actual products, let’s give you a few pointers on what to look for when buying one of these smartwatches.

Buyer’s Guide

Samsung Galaxy Watch Active 2

Samsung Galaxy Watch Active 2

What are the key features you should be looking at, before deciding which watch is the right one for you? We will find out together.

Standalone

Truth be told, not all watches work independently from a smartphone; some form their own LTE/3G/4G connection using a SIM card or eSIM card, while others act as an extension of a smartphone via Bluetooth. Wi-fi, Bluetooth, or standalone – which one do you prefer?

Battery life

Communicating wirelessly will deplete any battery in a short time, and charging up your smartwatch every night isn’t exactly what we dream about. Fitness tracking and other sensors will make sure you do, which is why you should make sure energy-saving modes are available when you’re on the go.

User Interface

These small devices require a smart UI, making them easy to use and practical; otherwise, what’s the point?

Tech companies are way ahead of ourselves, which is why they continuously upgrade and develop some of the smartest interfaces available – feel free to check out the latest Apple, Samsung or Garmin watches to get a glimpse of what we are talking about. A carefully designed UI can improve energy consumption as well as system performance.

Durability

First off, check the waterproof rating of every smartwatch. Will your device survive a splash, or will it join you while swimming? Will the screen handle scratches? This kind of questions should be answered before making a purchase.

Fees

It all depends on the carrier, but a compatible smartwatch available on that carrier must be synced with a phone on an existing plan. Even when used independently, the two devices will be sharing the same number. Also worth mentioning, the smartwatch may have a data use limit of its own; however, both the watch and smartphone will usually share the same plan.

The Best Smartwatches with SIM Cards

Now that you’ve seen a few things to look at when you’re buying your next smartwatch, let’s take a closer look at the 15 best smartwatches with SIM cards you could buy right now, starting with:

Apple Watch Series 5

Apple Watch Series 5

Apple Watch Series 5

Cellular-enabled, this excellent Apple-built smartwatch requires an iPhone to share a plan with. It will allow users to make calls or send texts, you’ll get social media or weather updates, and even benefit from Apple Music. Praised as the best LTE smartwatch around, packing GPS and 4G connectivity, the Apple Watch 5 Series shows off an incredibly sleek design.

Almost perfectly proportioned, and as heavy as we want it without becoming uncomfortable, this solid piece of technology is dustproof and waterproof – ideal for those of you of a more active nature. The metal wrist, the overall build quality – titanium or ceramic versions are also available – make this watch worth your time.

Speaking of which, most of you remember that battery life has been an issue with previous versions. You will get a day and a half, at the most, from this watch; an improvement for sure, but not that impressive. The 16m crystal clear HD display uses quite a lot of power.

However, this watch makes up for it by showing off a wide array of apps, such as the health diagnostics tools – it’s as close to a digital doctor you could get. You also get a wireless charger, 32GB of internal storage, and Apple’s dual-core S5 64-bit processor. A bit on the pricy side, the Apple Watch Series 5 is the best standalone smartwatch around – especially if you’re an avid iPhone user.

Samsung Gear S3

Samsung Gear S3

Samsung Gear S3

A solid upgrade from the Samsung Gear S2, this Android smartwatch is 3G/4G enabled and can be used independently from your phone, with GPS connectivity too.

The Samsung Gear S3 will gladly allow you to access social media, maps, weather, but phone features – calls and messages – are also included with the package. One downside, though – this device is only compatible with Samsung creations released after the Galaxy 6.

Showing off a sport-style, this watch features a distinctly circular dial. Bold yet comfortable, this elegant Samsung smartwatch comes with a rotating bezel specially designed to enable ease of navigation through the watch’s menus and apps – the AMOLED screen will definitely help out with that, and the fact that it can detect when you’re looking at it, increasing the screen brightness accordingly, is one hell of a feature.

With features in mind, we do recommend the Samsung Health and Health Monitor apps, which will make anyone passionate enough to keep track of their exercise, heart rates, and more. Modern and stylish, this device might be the ultimate Android smartwatch.

Putting out a classic vibe, this watch shows off all the premium features you might look for in a smartwatch. Powered by Android Wear OS, this watch comes with an interesting hardware specification. The understated exterior hides a Quad Core 1.2 GHz processor, 768MB of RAM, and a Qualcomm Snapdragon 400 that makes everything ‘tick’.

Thanks to its SIM card compatibility, this device will complete any task and possibly replace your phone. It’s not exactly flawless, because you won’t be able to take this watch swimming, but other than that, there is plenty to feel excited about.

Let’s not forget about the 1.38-inches P-OLED touchscreen and the wonderful front end. Could this make you forget about the Apple watch?

Here’s a watch from a relatively unknown brand, but a device that’s surprisingly good. The LEMFO KW88 will deliver the best performance, packed by a quad-core processor, 512MB of RAM and a 1.39-inches AMOLED touch screen. This thing will quickly make a lasting impression, and it comes with Android 5.1 OS as well.

Thanks to Google Play, users will be able to download some of their favorite apps directly to the watch. The built-in camera is a rare treat for a smartwatch, although the GPS, heart rate monitoring, and a pedometer are also welcomed.

Available at an affordable price, the BURG Neon 16A has plenty to offer if you’re new to the world of smartwatches. The specs list includes a 1.54-inch LCD touchscreen display, Micro SD support of up to 16GB, and a 3-day battery life before a new charge is required.

Limited, for obvious reasons, this watch still manages to impress. For instance, it supports all GSM networks and it will also provide two-way Bluetooth-based communication. Call me up and check it out. In the meantime, if you need fitness tracking abilities, you will have to look another way.

Ticwatch Pro

Ticwatch Pro

Ticwatch Pro

This smartwatch could be described as powerful, cheap, and very flexible. With a bold design and offering great value for your money, this device sets a high standard for Android smartwatches. The Ticwatch Pro, coming to you courtesy of Chinese company Mobvoi, is a piece of tech that can be used as a phone and communications device – no smartphone required.

Due to the fact that this smartwatch uses the Google Wear OS, it is compatible with way more apps than most smartwatches. Looking great, with a top-mounted black or silver bezel, this watch manages to show off a discreet yet interesting vibe.

There is a custom fitness app as well, called Fitness Pro, which will handle its business. But it’s that battery life that gets us very excited – up to 30 days on a single charge, although intense use will allow you about 5 days’ worth of fun. It’s still a lot more than most similar products on the market.

Samsung Galaxy Watch Active2

Samsung Galaxy Watch Active2

Samsung Galaxy Watch Active2

Samsung’s Galaxy Watch Active2 is more refined and a true challenger to Apple’s domination. It runs 4G and LTE, which means it is truly independent of your Samsung smartphone. An updated version of Samsung’s Tizen wearable OS makes sure this watch acts precisely and delivers a smooth experience.

This Galaxy Watch Active2 features a round 340 x 340 pixel AMOLED responsive touchscreen, which gives this watch an overall minimalist vibe, that’s appealing to both men and women. The rotary bezel navigation feature will feel natural and intuitive, that’s why we’re pretty sure everyone is generally pleased by this watch.

With a dual-core processor powering everything up, backed up by a 3-day battery, fitness addicts will have plenty of time to enjoy the dedicated apps included with this offering. The watch impresses with numerous features for fitness and health but unfortunately it’s not ok for swimming.

Garmin Vivoactive 3 Music

Garmin Vivoactive 3 Music

Garmin Vivoactive 3 Music

Garmin designed this watch primarily as a fitness and sports smartwatch, which might explain the excellent tracking software dedicated to such activities. Staying in shape requires time, which is why the manufacturer made sure that more-than-decent battery life will make your day.

4G and LTE enabled, the Garmin Vivoactive 3 Music will function independently of a phone while looking all stylish. It might be bulky and not at all meant for fashion events, but this thing will feel comfortable while working out and keeping healthy.

The 1.2-inch screen offers great colors while the side-swipe nav function is unique but works well. The Garmin watch is waterproof to 50 meters while battery life is impressive, allowing for up to 5 days of usage on a single charge.

Pradory Smart Watch

Pradory Smart Watch

Pradory Smart Watch

Running on Bluetooth 4.0 by default, you could consider this watch out of its time. However, it will deliver a range of up to 33 feet, as a compensation method. This almost ‘invisible’ wearable packs a 1.54-inch LCD panel and comes with waterproof capabilities.

Powered by a custom OS, yet compatible with most Android smartphones and iPhones, this thing won’t allow you to get bored.

It comes with a SIM card slot, making this a smartwatch phone – yes, making phone calls and sending text messages is possible, sans your smartphone. With up to 5-7 days of power on a full charge, this watch is really impressive, especially if you consider that only 30 minutes will be required to charge this thing up.

WJPILIS Smartwatch

WJPILIS Smart watch

WJPILIS Smart watch

Yet another unknown brand name, hopefully until now, WJPILIS also offers a standalone smartwatch with SIM. The overall design of this smartwatch is familiar, yet the wearable packs a camera on the front – something of a useful feature for a watch that you can use independently of a smartphone.

Yet again, we are dealing with a device that runs an independent operating system, which means Android fans and users will most likely not like it. Nonetheless, the smartwatch is able to use WhatsApp, Viber, or other apps to push through important notifications. The SIM allows this wearable to make or receive calls, while the MicroSD card slot also comes in handy.

Battery life is not that impressive, although one thing is not sure – is this watch waterproof or not? Feel free to find out, although we do not recommend you going crazy.
