eSIMs function similarly to traditional SIM cards. The main difference is that eSIMs transfer data directly to the mobile operator via the internet, without the need for an intermediate internet service provider. This direct connection is established using QR codes and specialized apps (such as eSIM Plus), eliminating the need for any physical actions when activating an eSIM.
