What is the mechanism behind eSIM technology?

Instead of a plastic card, your carrier profile is stored digitally on the phone. You purchase a plan online, receive a QR code via email, go to Settings, and scan it. The plan activates immediately—no hardware exchange needed, and the whole process takes under 2 minutes.
