What is an eSIM and why has Apple made the switch?
An eSIM allows carrier service to be integrated into the phone itself eliminating the need for a physical SIM card. Here in the US Apple’s iPhone 14 no longer has a SIM card slot and only supports eSIM technology. This allows the extra space in the phone to be used for other components.
Since the release of eSIM on iPhones it has become much easier to switch carriers which may result in users switching more often.
