Apple iPhone XS, XS Max to support a secondary eSIM option: Here's how it works
FirstpostExcept in China, Hong Kong and Macau, the dual-SIM setup for everyone else is a nano + e-SIM setup. Interestingly, for the rest of the world, Apple introduced a non-traditional dual-SIM setup on the iPhone XS and iPhone XS Max, where instead of a slot for two physical SIMs, it has one slot for a nano-SIM, and the other one is for a digital SIM aka eSIM aka embedded SIM. If you remember, last year, Apple launched the Apple Watch Series 3 cellular edition, which was the first product from the company that used an eSIM. At the moment only the Apple Watch Series 3 cellular variant houses an eSIM and you basically have to configure your existing Airtel or Jio SIM with the watch. With the eSIM on the Apple iPhone XS and iPhone XS Max, the eSIM will be a separate number in addition to the physical SIM card inside your device.
