Like with all Apple products, this feature too stands out. One of the SIM card slots is an actual physical one but the secondary SIM is an eSIM.

eSIM

The abbreviation stands for Embedded Subscriber Identity Module. It means the SIM is pre-installed in the device beforehand. No physically pulling it out like we do with traditional SIMs. It is activated remotely by the service providers and does all the functions of the traditional SIM cards.

In India, Apple is planning to partner with Reliance Jio and Airtel to provide eSIM support.
