How to find your IMEI and EID numbers
The fastest way to find your IMEI and EID is to dial *#06# on your phone's keypad. Both numbers appear instantly without making a call. The IMEI is your phone's device identifier. Every phone has one or two of them. The EID is the unique identifier for the embedded SIM chip; only phones that support eSIM have an EID. If you only see IMEI numbers with no EID, your phone is physical-SIM only.
Below: how to find each on iPhone and Android using the dialer code or Settings, what each number is for, and when Eflexsim might ask for one.
The fastest way: dial *#06#
Open your phone's dialer (the keypad you'd use to call someone), type *#06#, and the screen displays a list of identifiers. The format varies slightly by phone, but you'll typically see:
- IMEI 1: 15-digit number (for the first SIM slot or first eSIM).
- IMEI 2: another 15-digit number (for the second slot, if your phone has one).
- EID: 32-digit number (only on phones with an embedded SIM chip).
- Serial number: not always shown via dialer, but findable in Settings.
The dialer code works on iPhone, every Android version, and most older feature phones. It costs nothing, doesn't trigger an actual call, and works even with no SIM installed or no service.
If *#06# shows no EID but your phone is recent, some older Android builds hide the EID until you tap Show More or scroll inside the dialer result panel. Try scrolling, or check Settings as a backup.
How to find IMEI and EID on iPhone
The dialer works, but iPhone also exposes both numbers in Settings:
- Open Settings.
- Tap General โ About.
- Scroll down. You'll see:
- IMEI (and IMEI 2 if you have a dual-SIM iPhone)
- EID (on every iPhone XS and later)
- Carrier Lock (separately. Useful when checking if your iPhone is unlocked for an eSIM)
Long-press the IMEI or EID value to copy it. Useful if you need to paste into an email.
How to find IMEI and EID on Android
The dialer code works the same. Settings paths vary by manufacturer:
- Samsung Galaxy: Settings โ About phone โ Status information โ IMEI info (or "IMEI" for short).
- Google Pixel: Settings โ About phone โ IMEI / EID near the bottom.
- OnePlus: Settings โ About device โ IMEI.
- Motorola, Oppo, Sony: Settings โ About phone โ Status (or Phone status).
If you can't find the EID specifically, try the search bar in Settings. Type "EID" and the search usually surfaces the right screen.
What is the IMEI?
IMEI stands for International Mobile Equipment Identity. It's a 15-digit number that uniquely identifies your phone hardware. Phones with two physical SIM slots have two IMEIs (one per slot). Phones with one physical SIM and one eSIM also have two IMEIs.
What it's used for:
- Carrier registration. Your home carrier uses your IMEI to identify your specific device on their network.
- Stolen phone tracking. If your phone is stolen, the IMEI can be reported to carriers, who can block service on it across networks.
- Insurance claims. Phone insurance providers ask for the IMEI when you file a claim.
- Selling or trading in. Resale platforms verify a phone's IMEI to make sure it's not been reported lost or stolen.
IMEI is permanent. It doesn't change when you swap SIM cards, install eSIM profiles, or factory-reset the phone.
What is the EID?
EID stands for embedded UICC Identifier. It's a 32-digit number that uniquely identifies the embedded SIM chip in your phone. Every phone with eSIM support has exactly one EID. Phones without eSIM support don't have one.
What it's used for:
- Confirming your phone supports eSIM. The presence of an EID tells you the chip exists. Most online "is my phone eSIM-compatible" checkers look at the EID.
- Manual eSIM installation. When automatic QR scanning fails on some carriers (rare), the carrier may need your EID to push the eSIM profile manually.
- eSIM transfer between phones. When you move an eSIM from one phone to another using Apple's eSIM Quick Transfer or Google's eSIM Transfer, both phones exchange EIDs to authenticate the move.
Eflexsim almost never asks for your EID. Our standard install uses QR codes or activation links that contain everything needed. The EID becomes relevant only if support is helping you with a manual install or a phone-to-phone profile transfer.
When Eflexsim might ask for your IMEI or EID
In practice, almost never. Our standard flow is:
- You buy a plan. We send an activation email with a QR code.
- You scan the QR or tap the install link. The eSIM installs without us needing any device info.
Edge cases where support might ask:
- Failed install troubleshooting. If your phone repeatedly fails to install the eSIM and you email support, we may ask for your EID to verify your specific embedded chip and re-issue a profile that targets it.
- Phone-to-phone transfers when the original is broken. If your phone died with the eSIM installed and you want a fresh QR for a new phone, we may ask for the new phone's IMEI to confirm we're issuing to the right device.
- Stolen phone reports. If your phone is stolen with an Eflexsim eSIM installed, we'll ask for the IMEI to coordinate with the partner network's fraud team.
None of these are routine. Most travelers never give us either number.
Frequently asked questions
QCan I find my IMEI without unlocking my phone?
Yes. On most phones, the lock screen has an emergency dialer that accepts *#06#. The IMEI and EID appear without unlocking.
QMy phone shows two IMEIs. Which one is for the eSIM?
On phones with dual-SIM hardware (physical + eSIM, or two eSIMs), each line has its own IMEI. The labels usually clarify (IMEI 1 = physical SIM, IMEI 2 = eSIM, or similar) but the order varies. If you're submitting an IMEI for support and you're not sure which is which, send both. We'll figure out which applies to your eSIM.
QWhy doesn't my phone show an EID?
Most likely your phone doesn't have an embedded SIM chip. Phones from before 2018 generally don't. Check the model against our eSIM-compatible phones guide. A few region-restricted models (some India-market Galaxies, some Korean models) have the chip but firmware-block it. In those cases, the EID may also be hidden in Settings.
QShould I keep my IMEI and EID secret?
Treat them like a serial number. Not sensitive enough to require encryption, but not something to publish publicly either. The IMEI in particular can be used to report a phone stolen, so don't share screenshots of *#06# on social media (you might inadvertently dox your own phone's identifier).
QCan someone clone my phone if they have my IMEI?
No. IMEI cloning has been technically possible historically but isn't a realistic threat for travelers in 2026. Modern phones authenticate to networks using cryptographic keys stored on the SIM, not just the IMEI. Even if someone had your IMEI, they couldn't pose as your phone.
QDoes the EID change when I install a new eSIM?
No. The EID is the identifier for the chip itself, not for any specific profile. Installing new eSIMs adds profiles to the chip; the chip's EID stays the same forever.
For more on eSIM compatibility, see is my phone eSIM-compatible. The deeper background on EID specifically is in our what is an EID explainer. If your phone is carrier-locked and that's blocking install, see how to check if your phone is carrier-unlocked. If you're sharing your IMEI or EID with support, email support@eflexsim.com directly. Never paste these numbers into untrusted chat windows or third-party sites.
