Understand the IMEI Meaning

If you are wondering, “What is IMEI?” It acts like your phone’s digital fingerprint for identification and control. IMEI (International Mobile Equipment Identity) is a unique 15-digit device identifier. Every device has a different IMEI number that carriers and systems use to recognize your phone. If your phone is lost or stolen, you (or the police) can report the IMEI. Carriers then blacklist that IMEI so the device can’t connect anywhere. In effect, the phone becomes unusable on any network once its IMEI is blacklisted. Also, when you first activate a phone, the network checks the IMEI to make sure it’s allowed. Some carriers even tie phone locks to an IMEI.

Why the IMEI Number Is Important?

Your IMEI number is important for both security and functionality. Because it uniquely tags your device, networks rely on it to keep out unauthorized or fraudulent phones. Carriers maintain a central registry called the Equipment Identity Register (EIR) that lists all legitimate IMEIs. If a phone’s IMEI isn’t recognized or is marked bad, the network will block its calls and data. In practice, this means that knowing your IMEI can let you check a phone’s legitimacy and ensure your own phone isn’t mistakenly blacklisted. It also means that losing your IMEI (or exposing it to scammers) could let someone else misuse your device identity.

Check IMEI Number on iPhone Within a Few Minutes

Now that you know what IMEI is, let’s explore how to find IMEI on an iPhone in a few simple ways:

Using iPhone Settings: The simplest way is in Settings. On your iPhone, go to Settings > General > About. Scroll down, and you will see entries for “MEID” and “IMEI” (for older iPhones, the IMEI may be listed as MEID, which is essentially the first 14 digits of the IMEI). Apple’s support page confirms this: on the About screen, scroll until you find “IMEI/MEID”. This will show your full IMEI number. You can tap and hold it to copy if needed.

Using the Dial Code: Another universal method (works on most phones, not just iPhones) is to use the dial pad. Open the Phone app, go to the keypad, and dial *#06#. Immediately, your device will display its IMEI number on the screen. You don’t even have to press call; just typing the code is enough. The phone usually shows a pop-up with the IMEI. This is a quick way to check the IMEI without navigating menus.

How to Check IMEI on iPhone Without Turning It On?

It is not necessary to have a turned-on iPhone to check its IMEI number; you can simply do it even if it’s switched off, if you use these methods:

  • SIM Tray: If your iPhone supports SIM cards, you can find the IMEI number engraved on its tray. Many iPhones engrave the IMEI number on the inner side of the SIM tray that can be seen if looked at carefully.
  • Apple ID (iCloud) Account: You can see your iPhone’s IMEI number in your Apple account if you have enabled Find My Device.
  • Original Packaging: Apple prints the identifiers of your iPhone, like IMEI number and serial number, on the barcode label at the side of the original iPhone packaging. So you can simply check the box for it.

How to Check if an iPhone Is Unlocked Using IMEI

A “locked” iPhone is restricted to one carrier’s network (usually the one you bought it from). An “unlocked” iPhone can accept SIM cards from any carrier. If you purchase a new iPhone, it will be unlocked and can be connected to several carriers. In case of a second-hand iPhone, you have to make sure that it is unlocked without any active contracts with carriers. If you are wondering how to check if your iPhone is unlocked IMEI? Check like this:

  • Carrier Check: You can check the status of your iPhone by going to the carrier check website that many carriers offer. You just have to put your iPhone’s IMEI number there, and you will see the status.
  • Settings App: Go to your iPhone’s About in the settings. Look for the field labeled “Carrier Lock” or “Network Provider Lock”. If it says “No SIM restrictions”, then your iPhone is unlocked.
  • Use IMEI Checkers: There are third-party IMEI checking services (often paid) that can report your phone’s lock status. If you use one, be sure it’s a reputable service.

How IMEI Number vs SIM & eSIM Affects Device Identity?

Simply put, your IMEI is the phone’s ID card, while the SIM/eSIM identifies your subscriber information. Even if you swap a new SIM card into your phone, the IMEI stays the same. Here is a clearer distinction between the three:

Aspect IMEI Number SIM Card eSIM
What it identifies The device (hardware) The subscriber/account The subscriber/account (digital SIM)
Full form / ID International Mobile Equipment Identity ICCID (Integrated Circuit Card Identifier) ICCID (stored digitally)
Tied to Phone itself SIM card Phone’s embedded chip
Changes when the device is changed Yes, with a new device, you get a new IMEI number. You can reuse the same SIM card with a new device. You can reuse the same eSIM with a new device.
Role in the network Tells the carrier which device is connecting Tells the carrier who is using the network Same as SIM, but without a physical card
Security Features IMEI is very important in terms of maintaining your phone’s network security. It is important to keep the SIM card secure because if it is lost, your identity is compromised. eSIM security is popular for being unbreachable as it has no physical existence.

If you compare eSIM vs SIM, you will find a lot of differences, but they can work together. Modern eSIM-compatible devices often support dual SIM (one physical SIM + one eSIM, or even two eSIMs). How does IMEI work here? Each phone still has IMEI(s) for its physical hardware modules. In fact, on a dual-SIM iPhone, you will see IMEI1 and IMEI2 in Settings. Each line (SIM or eSIM) uses its own IMEI.

Can IMEI Numbers Affect eSIM Usage?

You might wonder if your phone’s IMEI has any special role when using eSIMs. It does, because carriers often require the IMEI for eSIM activation. When you purchase an eSIM plan (for example, a travel eSIM), the carrier may ask for your iPhone’s IMEI (and sometimes EID) during setup. It’s important to have your iPhone’s IMEI on hand if contacting a carrier to activate an eSIM. This is because carriers register the eSIM to your device’s identity. If you plan to use eSIMs (for travel or convenience), pick the best eSIM provider by considering a few factors:

  • Ease of use: Connecting with a reliable eSIM provider means less struggle in activating your eSIM. You don’t have to show multiple documents; just an unlocked phone and scanning a QR code will do.
  • Customer support: Having customer support that works 24/7 is an important feature that you should look for in a reliable eSIM provider. It helps you solve issues that can arise anytime.
  • Security: It is important to connect with a reliable and trusted eSIM provider because you have to expose your IMEI number.

Can Two Phones Have the Same IMEI?

By design, no two legitimate phones should share the same IMEI. The whole point of IMEI is uniqueness. If you ever encounter two phones with the same IMEI, that’s a major red flag. It usually means one of the phones is using a cloned or counterfeit IMEI.

Unfortunately, criminals sometimes copy (clone) a legitimate phone’s IMEI onto another device to commit fraud. This creates a pair of devices with the “same” IMEI. When networks detect this, they will blacklist the IMEI, effectively bricking both devices on that number.

Is It Safe to Share Your IMEI Number?

Your IMEI is like a serial number for your phone. It’s needed by carriers (for registration or support) and by buyers if you’re selling a phone. Sharing your IMEI with trusted parties (carrier, repair shop, or a buyer of your device) is generally fine. However, you should be cautious about broadcasting it publicly. If a malicious person learns your IMEI, they could potentially use it to clone your device or falsely report it stolen.
