Apple has introduced a technology called eSIM into its latest iPhones whereby the phones have dual-SIM capabilities but one is via a traditional physical SIM card (the phone has only one SIM Slot) and the other is an eSIM or embedded SIM. The technology allows users to change carriers without having to order a new SIM card or go to a shop. Instead, they could just sign up digitally.
Apple’s move with the eSIM is likely to worry mobile carriers because it allows users to switch providers quickly and frequently, heating up competition in what is a tough market for many operators.
