What Exactly Is an eSIM?
eSIM stands for Embedded SIM—a digital SIM built directly inside your smartphone. Unlike physical SIM cards, you don’t insert anything. You simply download a mobile data plan using a QR code.
- No physical SIM card required
- Install instantly by scanning a QR code
- Store multiple eSIMs in one device
- Perfect for international travel, short trips, digital nomads, and business travelers
In short: eSIM = a SIM card, but digital, convenient, and ready for travel.
How eSIM Works (QR Code, Activation Code, ICCID & APN)
When you purchase an eSIM from eSIMKitStore, you’ll receive:
- QR Code for installation
- Activation Code (SM-DP+ Address + Code)
- ICCID—your eSIM serial number
- APN settings (if manual setup is needed)
Your phone connects to the server, downloads the eSIM profile, and creates a fully functional mobile data line—just like a physical SIM card, but entirely digital.
