Do we need a SIM card for a smart watch?
How does a smart watch make and receive calls without a SIM card? Good question. Some smart watches, not all, come with something called an eSIM (read more about eSIMs). An eSIM (embedded SIM) is a type ofSIM card that is already built into your device, be it a smartphone, tablet or smart watch. Your watch can access the Internet via Wi-Fi, via a connected phone, or via an eSIM mobile network if the eSIM service is activated.
