What is an eSIM?

A “e” standing for embedded. This is a chip embedded (integrated) within a device, one that cannot be removed from a device.
If the eSIM is used on a wearable such as an Apple Watch or a computing device, it is easy to change your service provider with a simple phone call to replicate your phone number on the secondary device. A new eSIM will not be required, nor should there be any time delay in switching the eSIM.

How does eSIM work on Apple Watch 3?

With the announcement of the Apple Watch 3, Apple confirmed that the new connected version of the watch will be using an eSIM. It will be on the same number as your iPhone, so there will be a seamless experience across the two devices. For the Apple Watch 3, that means you can use messaging services, place calls, use mapping or stream music without your phone.
India will be seeing the eSIM technology, supported by Airtel and Reliance Jio, for the first time, with the Apple Watch series 3 arriving in stores this weekend.
