Smartwatch With SIM Card Buying Guide

Sim Card

Standalone smartwatches establish a 3G, 4G, or LTE connection using an eSIM card or SIM card.

SIM cards provide smartwatches with necessary access to a mobile network. This network allows the watch to make or receive text messages and phone calls, among other things.

In short, these standalone smartwatches are wrist companions that do not require a phone.

Phone Calls & Messages

Not many smartwatches allow two-way communication — letting your watch receive and send phone calls and text messages directly from your wrist.

They allow you to reply to your incoming emails and text messages with several different options: instant smart replies, keyboard typed, and speech-to-text.

Standalone smartwatches also let you dismiss, accept and initiate phone calls from the wrist itself.

It would be best to choose a standalone smartwatch that provides all the functionalities mentioned above.

Operating System

Most people already have smartphones, and almost all smartwatches are made to serve along with your smartphones.

Therefore, you need to consider the device’s compatibility before making a purchase.

There are two commonly used operating systems: Android and iOS. It would help if you got a smartwatch that can connect to your Apple or Android device.

Android Wear is Google’s operating system and works perfectly well with Android smartphones, like a pixel smartwatch. They also pair with iPhones, however, with restricted connectivity.

On the other hand, you should choose a Wear OS smartwatch if you have Android smartphone.


Smartwatches are more demanding than regular watches because of the number of features they have.

Therefore it is essential to focus on acquiring specific capabilities that lead to seamless functionality, even with the number of features:

Fitness Tracking

The majority of smartwatches with a SIM card include essential fitness tracking features such as step count notifications and pedometers.

However, if you’re a fitness buff and staying healthy is your primary goal, you should consider buying a standalone watch designed specifically for fitness tracking.

That’s because they will allow you to monitor heart rate, calorie counts, sports performance, and more.

Heart Rate Monitoring

Measuring and monitoring your heart rate is paramount if you want to track fitness levels or burn fat.

Some of the best fitness standalone smartwatches will monitor your heart rate during your workout or cardio exercise.

Not only this, but they will also track your heart rate when you’re resting.

Additionally, some trackers will also measure your recovery rate after a workout to inform you about your heart health.


Smartwatches with Wi-Fi connectivity can pair with local networks. It is probably the most crucial feature in any modern electronic companion.

It will allow uninterrupted connectivity for notifications and internet-dependent features.

Google Assistant

Google Assistant is an integral part of any Android standalone smartwatch.

It can dictate fast replies, initiate workouts, monitor weather updates, and a lot more, with a simple press of the ‘Assistant’ button.


Most new cellular smartwatches also have embedded GPS systems that allow wearers to track their pace and distance for fitness reasons.

In addition to that, it also provides you location-specific alerts. This could come in handy if you are buying a GPS smartwatch for your kid.

Also, if you prefer to do your workouts without the burden of carrying a smartphone, a smartwatch with a GPS tracker is the best option.


Many standalone smartwatches also come with cameras that can snap pictures, record videos, and more.

If you want to capture random moments during your day or want to record images of your workout routines, it’s a useful feature to look for!


When you buy premium standalone smartwatches, your primary concern will be the build quality.

Stainless steel is unquestionably one of the superior materials used for high-end standalone smartwatches. It’s durable, reliable, and resists discoloration or tarnation.

Apart from that, you can also choose a smartwatch with rubber or leather straps, as these are comfortable on the wrist for extended wear.

When making a purchase, look for crystal glass such as sapphire or mineral. These help to avoid scratches on the watch face.

Battery Life

Extensive battery life is essential for trails, hikes, or remote locations that require 3G, 4G, or LTE for connectivity.

Many standalone smartwatches provide a battery life that can last not more than a day, which is ideal for those who charge it regularly.

However, for fitness buffs and outdoor enthusiasts, a smartwatch with three to five days of battery life is perfect.

Nevertheless, smartwatches with SIM cards tend to have a battery life anywhere between eighteen hours to thirty days and more.

If you are looking specifically for smartwatches with long battery life, you should check out our guide on it.

Our Verdict

When smartwatches were first introduced, they worked as mere extensions to the smartphone. Requiring synchronization between both devices for optimal functionality.

Without this connection, they would function as just time-telling devices.

However, everything changed with standalone smartwatches. These devices allow you to make and receive messages, emails, and phone calls on the go without your smartphone.

Though all products we reviewed were exceptional, our top pick is Apple Watch Series 5.

It offers excellent features: 5ATM water resistance, superior build quality, larger screen, interchangeable bands, precise compass, embedded GPS and GLONASS, always-on display, ECG, optical and electrical heart sensors, emergency SOS, and more.
