Main Functions of Standalone Smartwatch with Cellular Functions

According to Wikipedia, the smartwatch has the capabilities of a computer in the form of a watch, and recent models have incorporated the touch interface on the watch surface. Different sensors and processing power are also included within the smartwatch to make it even more intelligent and provide useful information to the users.

Smartwatch has evolved and become an independent, standalone device without the need for a smartphone to support its features. You can wear your smartwatch without carrying a smartphone with you, and do all the usual activities with it.

Here are some common types of functions you can find on a Standalone Smartwatch:

  • make and receive calls with a SIM card or eSIM; cellular-enabled
  • receive text messages, and notifications from your smartphone
  • display time and date, alarm clock, timer, stopwatch
  • provide weather status and forecast
  • access Maps
  • play Music
  • track your swimming workout
  • GPS tracking
  • wireless payment
  • fitness tracking
  • health diagnostics like heart rate, ECG, blood oxygen
  • sleep monitoring
  • access to the manufacturer or third-party apps
fitness tracking
Smartwatch tracking your runs

We expect more advanced functions will be incorporated into the smartwatch in the next few years. With the Internet of Things becoming common in most places, Standalone Smartwatches are likely to be used in wider applications. There are already sensors within the smartwatch, more components could be added to increase its capability.

More and more smartwatch makers are adding cameras to it. Using the smartwatch to open a door or start a car is also likely to materialize. As long as humans can imagine, it could be the next function to consider.

Smartwatch with SIM

Comparing those smartwatches that need to work with a smartphone, smartwatches with a SIM allow you to work independently without a phone.

This is particularly useful for runners and swimmers who like to keep things light and simple. Smartwatch with sim can connect directly with the cellular provider, and provide instantaneous communication.

For runners, they can receive urgent calls during the run. Swimmers too can get direct notifications when people want to reach them, in the case of an emergency.

However, there is a drawback to a SIM smartwatch. You need to subscribe to a data plan every month, which in time, will add up a lot of money.

Smartwatch For Learning

One of the potential uses of the smartwatch is learning. In this aspect, we have yet to see any kind of application being developed and widely promoted in the market. Some research is pointing in this direction, and whoever comes up with the innovative learning idea using the smartwatch, they are likely to catch the market with a big wave.


Popular Brands of Standalone Smartwatch with SIM

These are the popular brands of Standalone Smartwatch come with SIM card or built-in eSIM you can find on the market:

1.Apple Inc.

Apple was founded in 1976 and introduced the first Apple Watch in 2015. Since then, it has released various series and uses watchOS on its smartwatch. The company has maintained its leading position in the smartwatch market, thanks to its iPhone popularity. The challenge now is improving the battery life of the Apple Watch. Apple has expanded the features of the smartwatch, allowing you to manage your calendar, delivers reminders, provide directions, enables interface with various applications without carrying your phone. Apple intends to make further contributions in the area of wellness and health segments. We shall see more developments from Apple in this market.


Samsung was founded in 1938 as a trading company and entered the electronics industry in the late 1960s as Samsung Electronics Co., Ltd. The first Samsung Smartwatch was Galaxy Gear released in 2013, as a companion for Samsung Galaxy Smartphones and Tablets. Since then, different models and versions have come on board from Gear Series (2013 to 2017) to Galaxy Watch Series (starting from 2018 till now). It has its own Smartwatch operating system called Tizen OS with the latest version 5.5 on Samsung Galaxy Watch 3. Rumor on the internet that Samsung may switch to WearOS from Google for its coming new Galaxy Watch 4 or Galaxy Watch Active 4 model to allow more apps development.

3.TicWatch (Mobvoi)

Mobvoi launched the TicWatch line of Smartwatches in 2015, powered by its own TicWear OS with Google operating system. It has since switched over to Google’s WearOS for its Pro version and is compatible with Android and iOS devices. There is a 4G/LTE version offered by Verizon for those who need a cellular connection on the go. It is empowered by Mobvoi’s proprietary layered display technology.

4.Fossil Group, Inc.

Fossil Group, Inc is an American fashion designer and watch manufacturer founded in 1984. Their brands include the famous Swiss Zodiac watches. The first smartwatch by Fossil was in 2015 and has since released more than 150 smartwatches, hybrid smartwatches, and fitness trackers throughout 40 countries.


The company was founded in 1987 as a technology company in China. Since then, it has expanded into many product lines including the smartwatch market. Huawei overtook Apple in 2018 as the 2nd biggest smartphone manufacturer in the world, after Samsung Electronics. The first Huawei Smartwatch was released in September 2015 and its own Harmony OS for the smartwatch was unveiled in 2019. Huawei also has its own app store call Huawei AppGallery, aiming to compete with Google’s Android Play Store.


Amazfit brand belongs to Zepp Health Corporation in China, which was founded in 2013 and formerly known as Huami Corp. In February 2021 the company name was changed to Zepp Health Corp. It has strong collaborations with other US companies like Timex Group and AliveCor Inc to incorporate more medical functionality within its smartwatches. In 2019, Zepp shipped 42.3 million smart wearable devices.

According to a Global Smartwatch market research in 1H2020, Apple is leading with a market share of 51.4%. Huawei and Samsung have 9.4% and 7.2% of the market respectively. Amazfit is getting popular recently climbing up fast with a 2.4% market share. For Fossil, it is in the niche designer watch market therefore market share is relatively small only at 2.1%. As for the TicWatch brand under Mobvoi corporation, the same for other smartwatch makers its share is negligible small to include in the market survey this round.

Apple and Samsung are constantly competing with each other. They have their own watch OS and have many developers supporting their apps at every new release. We expect them to launch new series every year.

More smartwatch makers are also joining the games and we expect more innovative products to be released in the coming years. There may be cross-over products appearing soon and one product which we foresee is the headband or eyewear market. How about a brain wave headset that able to control another device to open/close or on/off function? It is up to your imagination to come up with a new product which other has not thought about.

Standalone Smartwatch Best Suitable For Your Activities

If you check on the internet, there are a wide variety of smartwatches for you to buy. You need to decide what you intend to do with the smartwatch. A smartwatch is not to replace the smartphone completely, and it will never be (at least for a while). List down 3 to 5 of the activities below you intend to use the smartwatch for, and choose that smartwatch offering these features:

  • Swimming
  • running
  • cycling
  • Mountain hiking
  • casual exercise
  • dancing
  • e-payment
  • health monitoring

For example, if you wish to track your running performance and at the same time receive phone calls without carrying your phone with you. Choose a smartphone with a cellular function so you can leave your phone at home. At the same time, select the smartwatch with running apps with a full performance analysis report for you to review. You may omit those smartwatches with Ski or mountain hiking features, to avoid paying extra for these unnecessary functions.

Places to Buy Your Standalone Smartwatch

There are various popular marketplaces where you can buy different types of smartwatches. Amazon’s Online Store is our first choice when comes to buying and reviewing electronics products. You will be able to compare all the models and check user reviews before you make a final purchase.

The other alternative is to check on the manufacturer’s website and buy directly from them. However, we notice the price offered at Amazon is usually better if you wish to have a good deal.

4 thoughts on “11 Best Standalone Smartwatch With eSIM Cellular”

  1. Thanks for listing several standalone smartwatches. I’m actually interested to buy as a preparation after the lockdown period has been lifted in my country. My lifestyle isn’t that active, so I’m not interested in Galaxy Active or Amazfit. I’m also not a fan of Apple products, so it seems the Fossil ones is good for me. How do you think about it when comparing to Galaxy Watch Classic? 

    • Fossil design is very sleek and fashionable. Furthermore, it is a reputable watchmaker for many years so you can be assured of the performance and quality of the watch. The three buttons on the side are unique among all the smartwatches, especially the larger middle button which is a rotating crown for you to scroll through options or app menu. 

      Samsung Galaxy Watch Classic is rumored to be released in August this year. It will come with a new One UI Watch interface, which will be overlaid on top of the new Wear OS from Google. Users will be able to access the Google Play Store and Google apps. The load times for all the apps will also be faster, with a more accurate sensor reading.  

      The latest Fossil Gen 5 model uses Qualcomm Snapdragon Wear 3100, which is considered an older wearable chip. We expect the new Samsung Galaxy Watch Classic uses a newer wearable chip from Qualcomm. That should make the new Samsung Smartwatch a hot favorite among all Android users. 

  2. I like this article. I’ve never bought a smartwatch but my husband promised to get me one since he works in a tech shop. 
    I especially appreciate the part related to health and fitness and I love the fact that you did a list of different smartwatches so that people can choose the best one for them, as a smartwatch is not a cheap purchase. 


    • Dear Maja,

      Thank you for the comment. Happy for you to have a loving husband to buy you a standalone smartwatch with eSIM. He will be able to reach you wherever you go for any fitness run or exercise. 

      Comparing the features and benefits a smartwatch offering, it is value for money in fact. Moreover, you stand to learn another new skill/knowledge in your daily life which will become part of our lifestyle in the years to come. Wearable devices are going to be popular and vast in numbers and varieties for the next few years. 

      Each of us may carry one of them with us all day long to do some work or tasks and use it to turn on/off some appliances or equipment. It could even be our door or car at home or transportation in public places.  

      You may suggest your husband reviewing these 11 Best Standalone Smartwatches which we have listed here. Get him to get one for you and start enjoying the freedom of workout without carrying a smartphone. 

      Cheer to you, Maja for visiting our site!
