Emma More-McClune is GlobalData’s director of technical services. She stated that certain iPhone 14 models won’t have a physical SIM card slot. She said that Apple’s decision to discontinue the physical SIM card was a matter-of-fact.
AT&T’s vice president for mobile devices and accessories Jeff Howard said that the eSIM was a natural successor to traditional SIM slots.
An embedded SIM card called eSIM changes the physical SIM card to a virtual SIM card. It is embedded directly in the device and provides access to the operator’s network.
Apple applied for a patent in 2011 regarding eSIM. An eSIM has the advantage of allowing you to save space on your mobile phone for installing, for example, a larger batteries.
However, eSIM has its limitations. For example, users cannot change their mobile phone/operating number. You will need to visit the operator to replace the SIM card.
