eSIM is basically a virtual sim card that you can’t put inside a smartwatch or smartphone, to get eSIM functionality, you will have to contact your Sim provider (ex; Airtel, AT&T, etc) and they will activate the eSIM on your device.
If you have Cellular Smartwatches then you can use your existing SIM card on your smartphone as well as a smartwatch, just contact the SIM provider and they will duplicate your existing SIM Card and you will be able to use the internet and make calls directly from the smartwatch without the help of a smartphone.
Now, the biggest question is, how does eSIM Works? let’s find out…
