Last month, the Apple Watch Series 3 was finally launched in India through telecom operators Jio and Airtel. It’s Apple’s take on Dick Tracy and James Bond’s wrist watches. With it, you don’t need your phone on you to receive calls and messages.
This nifty feat is possible thanks to a technology called embedded SIMs (eSIMs). Unlike phones which use physical SIM cards to connect to cellular networks, the Apple Watch has an embedded microchip that essentially virtualises a SIM card’s functionalities. This allows it to connect to cellular networks.
