From Dominance to Obsolescence: The SIM Card's Journey.
The Subscriber Identity Module (SIM) card has been a staple of mobile phones for almost as long as they have existed, allowing users to easily transfer their cellular service from one phone to another. However, with the rise of embedded-SIM (eSIM) and integrated-SIM (iSIM) technology, the physical SIM card may soon become a thing of the past. While eSIM and iSIM offer potential security benefits, they also give device manufacturers and carriers more control over user access to subscriber information. The day is coming when consumers will have to say goodbye to their trusty SIM card.
