On Android Phones (Samsung, Pixel and more)
You can typically find the EID number on the phone's box. However, in case the brand that you’re purchasing does not print the EID number on the box, here’s an alternative way to find it within your device's settings:
- Access the Settings app.
- Scroll down to find "About Phone" and select it.
- Select "Status Information."
- The EID number should be one of the first pieces of information displayed.
Security and privacy considerations for your EID number
Your EID number is a unique identifier, and understanding its security implications is crucial. Like any sensitive data, it requires careful handling to protect your privacy and prevent unauthorized access. Here's what you need to know:
Can someone use your EID to hack your eSIM?
While there’s no direct risk of an eSIM hacking, the risk arises when this number is shared with untrusted parties, especially if they possess additional sensitive carrier account information. In such scenarios, unauthorized eSIM activation becomes a real possibility, potentially compromising your mobile service.
Think of your EID as a unique identifier that, when combined with other data, can grant access to your eSIM profile. Just as you wouldn't freely share the combination to a digital lock, your EID should remain private. This is why vigilance is crucial, and your EID should be treated with the same stringent confidentiality as your IMEI (International Mobile Equipment Identity) number.
How carriers use EID for network security
Carriers utilize EID numbers as a security measure to protect their networks and subscribers. EID numbers are typically encrypted, adding a layer of security that prevents unauthorized eSIM activation. This encryption ensures that only authorized devices can connect to the network, reducing the risk of fraudulent activity.
On top of this, EID numbers play a crucial role in blocking lost or stolen devices from being reactivated on a network. By associating the EID with the device and user account, carriers can effectively prevent unauthorized use, safeguarding both the network and the rightful owner.
Best practices for keeping your EID secure
It's important not to share your EID number publicly or with untrusted individuals. Treat it as confidential information, similar to your social security or passport number. Additionally, be mindful of public Wi-Fi safety when accessing your eSIM settings or carrier accounts online, and avoid using unsecured networks for these sensitive activities.
When activating your eSIM, utilize two-factor authentication (2FA) whenever available. This adds an extra layer of security, making it harder for unauthorized individuals to gain access. Lastly, be extremely cautious of phishing attempts or scams that request your EID. Legitimate carriers will rarely, if ever, ask for this information directly. If you receive such a request, verify its authenticity through official channels to protect yourself from potential fraud.
Troubleshooting common EID-related issues
Encountering problems with your EID can disrupt your eSIM experience. Here are some common problems and troubleshooting solutions, to ensure you stay connected no matter what:
