Buying Guide For The Best Smart Watch With Sim Card
While there are a lot of options available on the market for a smart watch, one can’t help but wonder why there is a need for one with a SIM card. To put it simply, having a SIM card on your watch simply brings it much closer to being a fully functional smartphone than it already is. If your smartwatch features a SIM card, you will be able to receive calls, send SMS, and also browse the internet without needing your smart phone in your hands.
A lot of people find it beneficial since it makes daily life so much easier and using the smart watch for your calls is certainly a great feeling which is possible thanks to TWS earphones and headphones. But, as there has been an overflow of smart watches in the market recently, it is simply amazing to see just how many options are there, even if you decide on a budget and feature set beforehand. To save you from the trouble of browsing for hours and hours to find a decent option, we have decided to bring the best options right here. If you need any more information about the smart watches mentioned here, kindly refer to our buying guide present right here.
1. Type of SIM
Before you pick up a smartwatch to use with your SIM card, you need to first check what type of SIM card is supported by the watch to ensure if it’s the right option for you. There are multiple options available for the type of SIM used by a watch such as a physical SIM or an eSIM. While both of these options can achieve the same results, having a physical SIM does have its advantages.
First of all, it does not restrict you to using just one SIM card and you can switch the SIMs as per your needs. Also, using an eSIM is only possible if your data carrier allows an eSIM connection, which is mostly adapted nowadays from most data carriers. However, using an eSIM is not optional in case you are going for a smartwatch that supports dual SIM cards. In such a case, you will be able to use a physical SIM in the watch whereas the other has to be an eSIM due to its compact form factor.
2. Battery Specifications
One of the few factors that affect the reliability of a smartwatch the most is its battery specification. The battery life of a smartwatch not only depends upon its battery capacity but also on the OS of the watch as well as its features and functionality along with your usage type. If your smart watch comes with an operating system like WearOS or WatchOS, you will have a wide range of functionalities available along with a dedicated app store to download more apps.
However, such smart watches usually have a very limited battery backup, up to 20 hours at best. On the other hand, smart watches that have a fixed set of features offer a very long battery backup. Some fitness-based smart watches can also go for as long as 30 days without needing a recharge. When it comes to smart watches with a SIM card, you can find great options that offer up to 180 hours of battery life.
3. UI and Aesthetics
A smart watch is not only a handy smart device like your smartphone, but also an integral part of your apparel like other watches. So, it is not an exaggeration to say that a smartwatch should be the right option in terms of looks and design to make it an ideal option for a user. The aesthetic factor of a smart watch includes many factors such as the dial size, the shape of the dial, the type of strap, the quality of the strap, and much more.
You will have to consider all of these features to find the best smartwatch. While the looks and colors are important for the exterior, the UI of a smart watch makes up for the internal design of the software and its features. A smart watch is only a suitable option if it is easier to navigate, not only when you are still, but also when you are on the move. And since you are buying a smart watch with a SIM, there are many more functions for you to see, and using the watch gets more and more complicated with more features.
4. Features
Lastly, we will talk about the one factor that makes these watches actually smart and beneficial to the user, the smart features. While there are a lot of options in the market that are marketed under the smart tag, not all of these watches are actually smart. In fact, a lot of brands have started to deliver fitbits and fitness bands with a large display under the tag smartwatch. If you want to get your hands on an actual smart watch, you need to carefully check the feature set offered by the watch.
Some of the few features that you will only find on a true smart watch are an operating system, a dedicated app store, calling features, and instant messaging. Other smart features that are not entirely necessary but definitely make the watch more useful include voice access, fitness tracking, blood oxygen level measurement, and other health-related features. While browsing for a smart watch, you will also come across a few options that feature a camera to allow video calls right from the watch, which is quite rare.
FAQs
If you wish to use a variety of applications on your smart watch, you need to pick up an option that is powered by WearOS or WatchOS. Such smart watches offer a truly smart user experience with a wide range of applications specifically developed for the watch. You can customize these watches the way you want and get the most use out of them. However, the battery life on such smart watches is not very reliable and you will have to charge these watches at least once every day.
While SIM card support has made it possible to place and receive calls from a smart watch directly, it is still not an efficient way of communication. First of all, you will need a pair of TWS or wireless earphones or headphones in order to communicate on the call. On top of that, you will also notice a slight degradation in terms of voice quality if you are placing a call from your watch. As for the video calls, the display of a smart watch is too small to have a proper video chat. Still, having a feature is always better than not having it when you need it.
There are many reasons why one would need a SIM card on a smart watch. If you are going on a morning jog and don’t want your phone with you, you can simply wear the watch and start your run. You can still stay connected to the world as you will receive SMS and calls on your watch. You can also browse the internet and stay updated with the news around you without needing your smartphone at all.
