We might soon see phones without actual SIM slots as more carriers worldwide adopt the eSIM standard. According to a story on The Wall Street Journal, some markets may only receive the eSIM version of Apple's next iPhone 14 series. Apple is not anticipated to completely transition all of its products from physical SIM to eSIM, instead choosing to see if consumers would be receptive to an eSIM-only phone.
According to reports, Apple has already alerted a number of significant US carriers to get ready for the arrival this Fall of its eSIM-only iPhone models. The primary benefit of removing the SIM slot from a phone is the release of limited interior physical space that may be used for other components. Another factor that will help users is security, as telecommunications can concurrently transmit security updates to millions of users.
