The Best Standalone Cellular Smartwatches

1. Apple Watch Series 5

Apple Cellular smartwatch

Apple Watch Series 5 allows you to leave your phone at home and use your smartwatch as your primary device for making calls and texts right from your wrist. It has a Cellular+ GPS connection of its own so it doesn’t depend on your phone for making calls or tracking your locations.

For cellular connections, it uses eSIM technology, which means that it does not have a regular SIM card slot but an integrated chip that works with all network carriers that support eSIM. However, the eSIM works on number sharing i.e. you will have to share your phone number with the watch. You can’t use a separate number on the watch.

But you can still use the watch to make calls while you leave your phone at home. The quality of audio calls you get on this smartwatch is also loud and crystal clear and as per the review of a customer on Amazon.

“The speaker on this smartwatch sound just like the iPhone 11 Pro speaker”.

Besides calls, you can also send and reply to text messages from this smartwatch over the cellular network.

It also has an integrated GPS chip that can track your location and give you detailed insights into your fitness activities like running, cycling, hiking, etc. Even if you listen to music while workouts you still don’t need to take your phone with you because you can stream music right on this smartwatch using your wireless earphones.

Apart from your phone, you can also leave your wallet at home because with this watch you can also pay for your purchases using the Apple Pay feature. Which overall makes this smartwatch a truly standalone device.

The other features that make this smartwatch a must-have are its large always-on retina display that makes every detail look amazing on the screen. Besides that this watch is also super useful for health tracking especially heart rate monitoring as it comes with a dedicated ECG app, which is great for people with heart problems.

Buying Guide For Standalone Smartwatches: A Guide To Go Phone-Free

SIM Card Support

The first thing you must look for in a standalone smartwatch is whether it supports a SIM card or not. Because without a SIM card cellular connectivity is not possible and you will always have to be tethered to your phone. Smartwatches come with two types of SIM support either one will do the work for you:

1. Physical SIM Support: Smartwatches that support a physical SIM,  have a SIM port where you can install a SIM card. Mainly a nano-SIM card goes into a smartwatch. But not most smartwatches feature a physical SIM because having a SIM port makes the smartwatch bigger and bulkier.

2. eSIM: A smartwatch with eSIM is in trend these days because with the eSIM you don’t have to remove and change the SIM every now and then. Also, it does not need a physical port which makes the watch lightweight and slimmer. However, not all carriers support eSIM as of now so that’s a downside of it.


To use your smartwatch as a standalone device it must have an integrated GPS chip otherwise you may have to be dependent on your smartphone’s GPS to track your activities and locations. Also having a GPS + Cellular connection on a smartwatch is great for sending SOS messages in distress.


Other than making calls and tracking locations, the other thing for which we use the phone most is for making payments. So if you want to go with a standalone watch that can help you go phone-free then it must have a feature to make payments as well.

Music Playback

If you are a music lover then having a music playback feature in your smartwatch is a must. Or you may not use it as a standalone device because you will still need your phone to listen to your favorite tracks. So try to find a smartwatch that comes with music playback functions.

Battery Life

Since you are going to use your smartphone as a standalone device it must have enough battery backup to last a full day. Because using cellular and GPS services eat up the battery very quickly.


How Much Does Monthly Plan Cost For Cellular Smartwatches?

It depends on the carrier you are using. Most of the time you will have to pay nothing because you are sharing your number with your smartphone.

Tom Nielson

Tom's love for watches started when his grandfather gifted him his Rolex watch when he turned 18! Being a teenager it was a big deal for him. Later when he got his first job he bought Fossil Palm Pilot back in 2003 which was a smartwatch. Since then smartwatches have come a long way and so is Tom's love for them. His experience with watches inspired him to start Wearholic and share his knowledge of wearables including watches, smartwatches, smart glasses, & smart clothing.
