It is very important to choose a design that fits perfectly on your wrists and is easy to operate with your fingers as it is going to accompany you the whole day.

If you have big fingers and you end up choosing a smartwatch with a small dial it will be a big hassle for you. Also, light and comfortable design are very important if you are into sports and other fitness activities.


Today smartwatches are loaded with ample features to allure customers but before buying the product you should first think about what exactly are your needs.

Whether you want a smartwatch with calling features and other basic functions or a fitness-focused smartwatch with a SIM card.


When you look for a standalone smartwatch, smooth and lag-free performance becomes of utmost importance.

Of course, no one wants a smartwatch that doesn’t sound properly over calls or lags while navigating between apps.


Most of the standalone smartwatches have average battery life. A long-battery life becomes crucial if you are out for a few days on a hike or somewhere relying on your smartwatch for connectivity and navigation.

Smartwatches can be very annoying if it just runs out of battery in between. A single day battery life is enough for people who can charge it daily but it is a big no for outdoor enthusiasts.

SIM Card Support

Not all standalone smartwatches come with a SIM slot and nowadays some latest smartwatches offer eSIM features that eliminate the use of a SIM slot.

However, as these watches have a pre-programmed carrier in it so it can be quite a hassle if you want to change your carrier. So you should consider your needs before buying any smartwatch with a SIM card slot.

So this was the article related to the best standalone smartwatch along with the buying guide. If you have any queries regarding this article, write your question in the below comment section.
