An eSIM is a digital SIM profile stored on a secure chip (eUICC) inside your device, no physical card needed. Carriers (like ORA partners 3HK or Sparks) issue these profiles, and you download them via a QR code.
📥 Download & Install
Scanning the ORA QR code tells your phone where to fetch the carrier’s eSIM credentials.
Your device then installs that profile onto the eUICC without needing a SIM tray.
🔄 Activation & Network Registration
After installation, enable Data Roaming for the eSIM in Settings → Cellular (iOS) or SIM card manager(Android).
Once you arrive in a covered region, the eSIM registers on the local network automatically—no further steps required.
🗂️ Multiple Profiles, One Chip
The eUICC can store several eSIM profiles (home and travel plans).
You toggle between them in settings; only one handles data at a time, but calls/texts on another can still come through if your phone supports Dual SIM Dual Standby.
In short, an eSIM embeds your carrier credentials digitally, scan a QR, install the profile, enable roaming, and you’re online instantly when you land. 😊
