What is the eSIM for the iPhone 15?

An embedded SIM, or eSIM for short, is a digital version of a SIM card. You don’t need to insert anything—it’s all done through your phone settings. On iPhone 15, especially U.S. models, there’s no physical SIM tray at all. Everything happens online, right from your phone.

You can store multiple carrier profiles, activate a plan in seconds, and manage it all from iPhone settings. The real magic? Dual eSIM. You can run two numbers at once—one for work and one for personal, or one local and one international when you travel.
