The best cheap smart watch SIM card in October

Using your Smartwatch independently of your Smartphone will require a separate SIM card.

With a low cost carrier (also known as an MVNO) this doesn't have to mean another costly bill. MVNOs provide cheap cell phone plans, while operating on the main US networks so you don't have to sacrifice coverage.

You'll find plenty of low cost SIM cards for your Smartwatch below, which we've broken down to help you find the perfect fit.

What is a SIM Card for a smart watch?

Once you're familiar with the two types of smartwatches, explore SIM cards and the way they can help you make the most of this device.

A SIM card, where SIM stands for Subscriber Identity Module, is a small chip you can insert into a smartphone, standalone smartwatch and more.

When it connects your device to a cellular network, a smart watch SIM card transforms your watch into a valuable means for communication.

A standard, Nano or micro SIM then carries information about you and your mobile carrier, so, by sliding a small chip into the card slot, you can give your device access to phone number information, contacts and the like in one go.
