The answer is it depends on the type of smartwatch that you have. There are smart wearables with Bluetooth that need to be connected to a smartphone or a tablet.

In addition, they come with a SIM card slot. They are able to connect to LTE, 3G, 4G, and 5G networks. Some will offer you the option to pair it with a smartphone too.

Which one is the best standalone smartwatch for me

  • Apple Watch Series 5

Apple Watch (Find out more about this smartwatch with built-in GPS and cellular functionality on Amazon) was released on 9/20/2019 with some great updates such as the Always-on Retina display which means that the screen will stay on. Also, unlike the Apple 4, it has more storage (32 GB), features a compass, and the cellular version allows you to make emergency calls in other countries.

  • ANCwear Smartwatch

For a budget price, you can get the ANCwear smartwatch with a SIM card. This phone watch can make and receive calls, send and receive messages, and runs social networks apps. Also, you can use the ANCwear as a watch only via Bluetooth. This watch tracks sleep quality, steps, and more alert. It takes half an hour of charging and it can be up to 5 to 7 days with full power.

  • Samsung Galaxy Watch Smartwatch

This smartwatch (See this Amazon bestseller to find out), which has an E-sim card, works with all carriers such as At&t, Verizon, Sprint and T-Mobile. However, it will not work as a standalone voice device on Sprint. To At&t customers, you will need to contact AT&T to activate the sim card. You need to make sure that your carrier is E-sim compatible. It has a 4 GB storage, 1.5GB RAM. It will work with a Samsung Phone S7 and up to set up LTE.


Smartphones with SIM cards or smart wristwatches that can make phone calls are a great convenience if you don’t like to depend on your phone. In my particular case, having a standalone smartphone will be interesting and something new because I am so used to my phone.

However, there are a few things that will have to improve before I can invest in one. First, as of right now, smartphone watches will still require a phone which means if you want to enable the cell phone function you will have a wireless service plan. Another feature I would like to improve is sending texts. Many watch phone screens are smaller and you will have to type with one finger.

I know that watch phones will get better and better. New functionalities and improved features will be part of a new generation of smartwatches.
