This new technology allows you to ditch plastic SIM cards, easily switch between carriers, and have two phone numbers on one phone.
Samsung's Galaxy S20 and Galaxy Z Flip are joining the iPhone 11, Pixel 4, Galaxy Fold and the new, foldable Motorola Razr as the small handful of phones that use a new technology called eSIM. What that means depends on the phone. For some, like the Razr, you can ditch your plastic SIM card altogether. For others, like the iPhone 11 and Galaxy S20, you can have two phone numbers assigned to one phone.
