What is an EID Number?
An <strong>EID</strong> (Embedded Integrated Circuit Card Identifier) is a unique 15-digit number that identifies the eSIM chip in your device. It's essential for activating eSIM services, as carriers need this number to configure your device.
Why is the EID Number Important?
The EID number is a crucial component in the eSIM activation process. Without it, carriers cannot configure eSIM services for your device. It ensures your device can connect to the correct network and receive the appropriate service configuration.
How to Find the EID Number on Your Device
On iPhone Devices
- 1.Open Settings
- 2.Tap General
- 3.Tap About
- 4.Scroll down to find EID (if your device supports eSIM)
On Android Devices
- 1.Open Settings
- 2.Tap About phone or About device
- 3.Look for EID in the device information
- 4.Alternatively, go to Settings → Network & Internet → Mobile network → Advanced → EID
Note: Not all devices display the EID in settings. Some carriers may require you to contact them directly to obtain your EID number.

Your EID number is sensitive information that should be treated with care:
- •Only share your EID with trusted carriers and eSIM providers
- •Be cautious of unsolicited requests for your EID
