A smartwatch with LTE support can make phone calls and send texts just like any smartphone! Some smartwatches have Bluetooth calling features that support phone-free calling, but you need your smartphone nearby to do so.

Best Smartwatch Make Calls without Phone

If you want to make phone calls even when you are far away from your smartphone, you need a smartphone with 3/4G or LTE connectivity. A smartwatch with 3/4G or LTE support can directly connect to the cellular network and doesn’t need a paired smartphone to make phone calls.

A smartwatch with LTE Technology costs you extra as it comes with additional hardware components. Plus, you may require a separate data plan for the cellular smartwatch. Fortunately, you can use the same number on your smartwatch and smartphone. It allows you to answer calls on either device.


Besides, a standalone smartwatch with LTE support does not require a physical SIM. Instead, it uses a virtual or e-SIM that you can activate just by calling your cellular provider, and it takes only a few minutes! So, you don’t need to go to a shop to buy a SIM card and then break the smartwatch to insert a SIM card like in the old days.

You should ensure that the smartwatch watch that you are going to buy should have good sound and voice quality. Otherwise, it will be frustrating. Also, you should check the smartwatch’s battery life, as some devices may not last long when used for making calls.

After long research and our own experience, I have compiled a list of the best smartwatch make phone calls in 2023. The watches listed here are top-notch and ensure a great experience when used for making phone calls.

Apple watch series 8

Apple Watch Series 8 is one of the best health and fitness tracking smartwatches you can buy in 2023. The LTE+GPS variant comes with an eSIM which allows you to make or receive phone calls, send text messages, and even use internet-based apps without your iPhone nearby.

The Apple Watch Series 8 is available in 41 and 45-mm sizes, and both variants feature an always-on retina display with 352×430 in the 41-mm variant and 396×484 in the 45-mm variant. It is available in stainless steel and aluminum finishes with various strap options. Both the variants are water-resistant up to a depth of 50 meters and track swimming.

The temperature monitoring sensor in Apple Watch Series 8 does not take your skin temperature but can detect temperature variation during ovulation in females, which helps plan a pregnancy. The car crash detection feature uses the smartwatch’s built-in accelerometer and gyroscope to automatically detect a crash and call emergency services with your location.

The Apple Watch Series 8 has a highly accurate built-in GPS sensor that easily tracks your outdoor workout activities like running, hiking, mountain biking, etc. The watch supports music streaming apps such as Spotify, Deezer, and Apple Music and even allows you to download your favorite tracks into the watch. Since this watch has cellular/4 G support, you dont need your iPhone for music streaming.

The battery life of the Apple Watch Series 8 is 18 hours, just like older generation Apple Watches. However, the Apple Watch Series 8 and Apple Watch Ultra have a Low Power Mode that can extend the battery life by about 36 hours, killing some features such as an always-on display. Unfortunately, the watch can last only 1-2 hours when connected to the LTE, which is a huge drawback.

The Apple Watch Series 8 is one of the best smartwatches with LTE support that you can buy. It has a sleek design, top-notch display, and accurate fitness tracking features. However, the watch’s battery life is not good compared to other smartwatches with similar features and specs.

The Apple Watch Ultra has a high-quality rectangle display protected by Sapphire crystal glass, which is more resistant to scratches than the regular glass used in most smartwatches. The watch also has an always-on display and a unique  Wayfinder watch face. The Wayfinder watch face includes a built-in compass and eight complications to give you as much information on your wrist as possible.

If we compare the health tracking features of the Apple Watch Ultra and Apple Watch Series 8, both have the same features. The FDA Approved Electrocardiogram(ECG/EKG), Blood oxygen level monitoring, and Irregular heart rate alerts are a few of the health tracking features.

The Apple Watch Ultra has MIL-STD20-810H certification and works in extreme temperatures and cold environments(20°-55° C). It has 100 meters of water resistance like advanced Garmin watches such as the Fenix 7, Epix Gen 2, and Garmin Enduro 2.

The Apple Watch Ultra is for outdoor enthusiasts! But while the new Apple Watch Ultra may be an excellent tool for athletes and outdoorsy types, it’s not perfect.

Nevertheless, the Apple Watch Ultra is a solid smartwatch that should appeal to a wide range of users.

Google Pixel Watch

Google has been working on its own smartwatch for many years, but the release of the Pixel Watch has been delayed many times. Initially, the watch was supposed to be released alongside the original Pixel phone in 2016. However, due to unknown reasons, the release was pushed back, and it wasn’t until October 2022 that the watch was actually released.

The Pixel watch lacks many features of the Google-owned Fitbit, such as temperature and SpO2 monitoring. However, Google Pixel features an LTE function that is unavailable in any Fitbit watch. Like modern watches, the Pixel watch also features an eSIM, making it very convenient to activate cellular functions without needing a physical SIM card.

Since it got a high-quality built-in speaker and mic, the quality of phone calls is very clear. You can also access Google Assistant and give commands to make phone calls, send messages, set alarms, and much more. On the other hand, if you prefer a Pixel watch without LTE(Wi-Fi and Bluetooth), it still supports Bluetooth calling, but you need to have your paired smartphone with you.

The Google Pixel Watch has a high-quality AMOLED color display, protected by the Corning® Gorilla® Glass 5, which makes it less vulnerable to scratches. It also has an always-on display mode to see the time and your notifications even when the watch is not actively used. The Pixel Watch is also water-resistant up to 50 meters, making it perfect for swimming or other activities where you might get wet.

The health tracking features in the Pixel watch are by Fitbit. This means that you can get most of the features of Fitbit, such as an FDA Approved ECG, heart rate zone minutes, stress tracking, continuous heart rate monitoring, etc. However, the Google Pixel watch does not have features like skin temperature monitoring or SpO2 Monitoring.

The Google Pixel watch has an impressive 24 hours of battery life in smartwatch mode. With GPS, the watch gives 12 hours of battery life, which is impressive. If we look at the charging time, the Pixel watch takes about 55 minutes to reach 80% and 80 minutes to get 100%.

The Google Pixel watch is an excellent smartwatch with LTE support, allowing you to make phone calls without your smartphone. However, the LTE feature in Google Pixel watches currently support only in limited countries and carriers. You can get the full list of regions and carriers from Google’s website. Plus, the high price tag and absence of some health tracking features may disappoint some users.


  • Attractive design
  • Good call quality
  • FDA Approved ECG
  • Highly accurate GPS
  • Emergency SOS and fall detection
  • Music streaming and storage


  • High price
  • Only available in one size(41mm)

In addition to making calls, this smartwatch can stream music via streaming apps such as Apple Music, Spotify, or Pandora. It also supports many other internet-based apps such as weather, Maps, and so on, allowing you to stay connected even if you don’t have a smartphone with you.

This means you can easily read and view your messages and callers’ names. Plus, it also has a specially designed QWERTY keyboard which brings your typing experience to the next level.

The Apple Watch Series 7 has many health tracking features such as Electrocardiogram (ECG/EKG), Blood oxygen level monitoring, sleep tracking, and many more. The ECG in Apple Watch Series 4 and above variants are validated by the Federal Drug Administration (FDA) and thus is more reliable in detecting Atrial Fibrillation(AFib) and irregular heart rates.

Apple Watch Series 7 with LTE also features a built-in GPS and fall detection feature, which can automatically call emergency assistance if it detects a fall, and you are unresponsive for more than a minute. The Series 7 without cellular also has this feature, but you need to have your iPhone with you to use it.

The only downside of the Apple Series 7 is its battery life! Like every other Apple Watches, the Series 7 lasts for about 18 hours only in standard usage. The battery may drain even faster if you use features like calling, GPS, music streaming, etc. However, for a slight relief, the Series 7 charges faster than any other Apple Watches, and it takes only 45 minutes to charge from 0% to 80%.

The Apple Watch Series 7 with LTE is an excellent smartwatch with many features, such as making phone calls, streaming music, fitness tracking, etc. If your budget allows, then the Apple Watch Series 7 is your best pick!

13. Apple Watch Series 3 LTE+ GPS

Apple Watch Series 3 with Cellular

Even though it is an older watch, the Apple Watch Series 3 is still a fantastic smartwatch with excellent voice call quality. Like top models from Apple, the Series 3 also has a good speaker and microphone, allowing phone-free calling.

Apple Watch Series 3 does not have a music streaming or storage feature, but it allows smartphone music control from your wrist. This means that if you like to listen to songs while running, you must carry your smartphone along with you. Otherwise, you should consider the Apple Watch SE or Series 6, which have the music streaming feature.

Apple Watch Series 3 LTE is supported by multiple carriers and countries, including the US, U.K., Canada, Australia, and more. You can have the complete list here. Even though it is an older generation of Apple Watch, it uses e-SIM for cellular connectivity, which you can easily activate via supported carriers in your area.

Many countries, including the US, Canada, the UK, etc., support the Apple Watch Series 3 calling feature. Carriers like AT&T, Verizon, T-Mobile, Sprint, and more offer support for Series 3 LTE, and if you are on any of these carriers, you can use the cellular feature on your wrist. The good news is that the Series 3 LTE+GPS watch uses e-SIM support, which makes it easier to use and activate the cellular feature.

The Apple Watch Series 3 has an OLED display with a resolution of 272 x 340 pixels(38mm) or 312 x 390 pixels (42mm). Even if it is not bright as high-end Apple wearables, you can clearly see the content on the screen under direct sunlight.

LTE and non-LTE variants feature a built-in GPS, accelerometer, and barometric altimeter to track your various indoor and outdoor activities accurately. The swim-proof smartwatch (5ATM) can track your swimming metrics, including stroke type, distance, and pace.

The Apple Watch Series 3 has a pretty accurate optical heart rate sensor that uses LED lights to calculate your heart rate. But it does not have advanced health tracking features such as SpO2 or FDA Approved ECG. The Electrocardiogram (ECG) feature is available only on the Apple Watch Series 4 and above versions, whereas the SpO2 Sensor is accessible on Series 6 and above.

The battery of the Series 3 is 18 hours, just like every Apple Watches! However, with continuous LTE usage, the battery dies even faster. As a result, you won’t be able to use all the watch’s features for a complete day if you are not near the charger.

Of course, the Apple Watch Series 3 is an affordable option for iPhone users. However, it does not have advanced health-tracking features such as ECG or SpO2. The watch also has a small screen compared to the later variants. So Apple Watch SE is a better alternative even though it costs a bit more.


  • Affordable
  • Essential Fitness tracking features
  • Music streaming support via Apple Music
  • 5 ATM water-resistance


  • Limited features
  • LTE setup is complicated
  • Battery dies faster when connected to the cellular network.

14. Fossil Gen 5 LTE Variant

Fossil Gen 5 LTE Smartwatch

At launch, Fossil Gen 5 came without an LTE variant, but later, the company added an LTE variant to the Gen 5 series. Fossil has recently launched Gen 6 watch, but unfortunately, it does not have a cellular variant yet. So, if you need a Fossil watch with LTE technology, the Gen 5 is your only option for you. 

Verizon is currently the only supported carrier for the Fossil Gen 5 Cellular smartwatch in the USA. In the future, other companies may provide LTE support, but as of now, it is not available. If you are with Verizon, you can use the same mobile number on your smartphone and smartwatch via Verizon Number Share Plan.

The quality of calls is not as good as a smartphone. When tested, the person on the other end could not hear the voice properly, and the Smartwatch had to be brought close to my face to listen to the voice. In a nutshell, the Fossil Gen 5 LTE watch offers acceptable call quality, but if you need more freedom, you might want to consider other options.

The Fossil gen 5 Cellar watch has a 1.28-inch AMOLED touchscreen display and 416 x 416 resolution. The case of this smartwatch is made of stainless steel and has a swappable silicone strap. Its water-resistance rating is only 30 meters making it less suitable for swimming and other water-based activities.

“We recommend a smartwatch with at least 5ATM water resistance for swimming purposes.”

The watch uses Qualcomm Snapdragon Wear 3100 with 1GB RAM and 8GB storage. That said, the available storage is about 4 GB for the user because the system OS uses the rest. Plus, it also has a built-in GPS to track your outdoor activities more accurately.

The Fossil Gen 5 watch uses a PPG Sensor for heart rate monitoring, which is more reliable and accurate than the Gen 4 watch. It does not have advanced health trackings features like SpO2 or irregular heart rate detection in Samsung Galaxy Watch 4 or Samsung Galaxy Watch 4.

I would say that the Fossil Gen 5 is a more fashion-focused smartwatch with basic health and fitness tracking features, and it does not have health tracking features such as ECG or blood oxygen level monitoring. So, if you can add a few more bucks for your next LTE smartwatch, consider Galaxy Watch 4 or TicWatch Pro 3.


  • Fashion focussed smartwatch
  • Built-in GPS
  • 5 ATM water resistance
  • Custom battery modes


  • No Wear OS 3.0
  • Verizon is the only supported carrier
