What Is an IMEI Number and Why It’s Important

What Is an IMEI Number?

An IMEI, or International Mobile Equipment Identity, is a unique 15-digit number assigned to every mobile device. Think of it as your phone’s fingerprint—it identifies your device from millions of others around the world. Unlike your SIM card, which can be removed or replaced, the IMEI is tied directly to your phone’s hardware and cannot be changed without special tools. Manufacturers and carriers use this number to track devices, block stolen phones, and check eligibility for unlocking.

How IMEI Connects to Unlock Status

Your IMEI number plays a big role in determining whether your phone is carrier locked or unlocked. When you buy a phone through a carrier—especially with a payment plan—it’s often locked to that carrier. The carrier uses your phone’s IMEI to apply or remove this lock. If your phone is paid off and meets the unlock requirements, the carrier can update your IMEI in their system to reflect an unlocked status. It’s also important to note that an IMEI lock is not the same as a SIM card lock (like PIN or PUK codes). While SIM locks deal with protecting your SIM card from unauthorized access, an IMEI lock restricts which networks your device can use.

How to Find Your IMEI Number

Method 1 – Dial a Code

One of the quickest ways to find your IMEI number is by dialing a simple code on your phone. Just open your dial pad and enter *#06#. As soon as you hit the last character, your phone will automatically display a screen showing your IMEI number. This method works on almost every mobile device, regardless of the brand or carrier.

Method 2 – Check in Settings

You can also find your IMEI number directly in your phone’s settings. If you’re using an iPhone, go to Settings > General > About and scroll down until you see the IMEI listed. For most Android devices, including Samsung Galaxy phones, navigate to Settings > About Phone, and the IMEI number will appear there. It’s usually listed along with other information like the serial number and model name.

Method 3 – On the Physical Phone

If your phone won’t turn on or you can’t access the settings, there’s still a way to locate your IMEI. Many phones print the IMEI on the SIM card tray, so simply remove the tray and look for the number. Some models also list the IMEI on the back of the phone, near the bottom, or on the original box label that came with your device. This is especially helpful when checking the unlock status of a used or secondhand phone.

TL;DR:

You can quickly check if your phone is unlocked by dialing *#06# to get your IMEI number. Use your carrier’s official IMEI checker or a trusted site like IMEI.info to verify the unlock status. iPhone users can also check under Settings > General > About for “No SIM restrictions.” On Android, inserting a SIM card from a different carrier is a simple way to test. Always confirm unlock status before switching carriers or buying/selling a phone.

How to Use IMEI to Check If Your Phone Is Unlocked (Step-by-Step Guide)

Step 1: Use Your Carrier’s Online Tool

Many carriers offer a dedicated online tool to check your phone’s unlock status using your IMEI number. This is often the most accurate way to get official confirmation.

• AT&T Users: Visit AT&T’s IMEI Unlock Portal and enter your IMEI. The system will tell you if your device is eligible for unlocking or already unlocked.
• T-Mobile Users: Use the T-Mobile Device Unlock page to check unlock eligibility with your IMEI.
• Verizon Users: Most Verizon phones are already unlocked after activation, but you can still contact their support or check your account to confirm using your IMEI.

Pros:

• Accurate, official information directly from the carrier
• Includes unlock eligibility status and payment/contract info

Cons:

• You may need an active account with that carrier
• Not always accessible to non-customers or buyers of secondhand phones

Step 2: Use a Trusted IMEI Checker Website

If you can’t access a carrier-specific portal—or you want a quick overview—try using a reliable IMEI checker website.

• IMEI.info: Shows lock status, model, and sometimes blacklist info
• Swappa IMEI Checker: Great for checking if your phone is clean and unlocked before reselling or buying
• DoctorSIM: Offers more detailed unlock and carrier history (some tools are paid)

These tools use public databases and may be helpful for getting basic insights. They work well for Samsung, iPhones, Pixel, and other Android devices.

Important: Be cautious—not all IMEI checker sites are safe.
Avoid any website that asks for payment before showing results, or that doesn’t have reviews or HTTPS security. Stick with trusted names and never enter your IMEI on sketchy forums or apps.

Step 3: Call or Chat With Carrier Support

If online tools leave you confused or unclear, you can contact your carrier directly for the most accurate answer.

• Call or open a live chat with AT&T, T-Mobile, or Verizon
• Provide your IMEI number when asked
• Request confirmation if your phone is fully unlocked or still carrier-bound

This method may take a few minutes, but it’s often the best way to resolve complex cases (like if the device was financed or part of a trade-in).

Bonus Tip: When calling, be ready with other info like your account number, phone number, or device receipt (if secondhand). Carriers may ask these for security reasons.

How to Know If Your Phone Is Locked (Without IMEI)

Sometimes you might not have access to your IMEI number right away, or you just want a quick and simple method to see if your phone is locked. Here are three reliable ways to check unlock status without using your IMEI.

Use a Different SIM Card

One of the easiest ways to find out if your phone is unlocked is by using a SIM card from a different carrier.

Step 1: Power off your phone and remove the current SIM card.
Step 2: Insert a SIM card from another network (for example, if your current SIM is from AT&T, try inserting a T-Mobile or Verizon SIM).
Step 3: Power the phone back on and watch what happens.

If the phone accepts the new SIM and lets you make calls or use data, it’s unlocked. But if you see a message like “SIM Not Supported,” “SIM Network Unlock PIN,” or “Enter Unlock Code,” your phone is still locked to the original carrier. This method works well for both iPhones and Android devices and gives you a quick answer.

iPhone Specific: Check in Settings

If you’re using an iPhone running iOS 14 or later, there’s a built-in way to check your unlock status through the settings.

Step 1: Go to Settings > General > About
Step 2: Scroll down until you see a section called Carrier Lock or Network Provider Lock
Step 3: Look at the message displayed there

If it says “No SIM restrictions,” your iPhone is fully unlocked. If it shows anything else, it may still be tied to a specific carrier.

Android (Samsung, Pixel, Moto, etc.)

For Android phones, there’s no direct setting like on iPhones, but you can still find out using basic tests.

Option 1: Just like the method above, insert a SIM card from another carrier and check if it works.
Option 2 (T-Mobile devices): Use the Device Unlock App found in the apps list. Open the app and select Device Unlock > Permanent Unlock to see your status.

If the phone unlocks successfully or lets you proceed with setup, it’s not locked. If the app says you’re ineligible or prompts for a code, the device is still carrier-restricted.

These hands-on methods are quick and don’t require any technical tools—making them perfect for checking a phone’s status before switching carriers, buying, or selling.

Brand-Specific Unlock Check Examples (IMEI-Based)

How to Check if My Samsung Phone is Unlocked

For Samsung phones, you can use several simple ways to check if the device is unlocked. First, dial *#06# to get the IMEI number and enter it into a trusted online IMEI checker. These tools will tell you if your phone is carrier-locked or ready for any network. You can also open the Samsung Members App, which sometimes shows network status and compatibility under support or diagnostics. Another quick test is inserting a SIM card from a different carrier. If the phone connects to the network without asking for an unlock code, it’s likely unlocked.

How to Check if My T-Mobile Phone is Unlocked

T-Mobile offers a couple of built-in ways to confirm unlock status. One is through the Device Unlock App, which is pre-installed on many T-Mobile Android devices. Open the app and select Permanent Unlock—if the process completes or says the phone is already unlocked, you’re good to go. You can also go to your T-Mobile account dashboard online and enter your IMEI to check if the device qualifies for unlocking. This method is accurate and works best for current customers with active service.

How to Tell if Galaxy S23/S24/S25 Ultra Is Unlocked

To check if your Galaxy S23, S24, or S25 Ultra is unlocked, start by locating the IMEI via *#06# or Settings > About Phone > Status > IMEI Information. Use that IMEI on a checker site or ask your carrier directly. You can also test with a non-native SIM card—for instance, insert a SIM from a different carrier like T-Mobile, Verizon, or AT&T. If the phone accepts it and shows signal bars, it’s unlocked. Another way is to check under Settings > About Phone > Status > Network to see current network restrictions.

How to Tell if Moto G Is Unlocked

If you have a Moto G, the first step is to dial *#06# and write down your IMEI. From there, you can check unlock status using a universal IMEI checker online or by reaching out to Motorola support, especially if the phone was purchased through a specific carrier. Motorola’s team can verify whether the IMEI is still tied to a carrier or fully unlocked. You can also insert a SIM card from another provider and test if the phone works without a prompt for an unlock code. If it does, your Moto G is most likely unlocked.

IMEI Unlock Status Codes – What They Mean

Sample Unlock Status Results

When you check your phone’s IMEI using a carrier portal or third-party tool, you’ll often see specific terms that indicate the phone’s current unlock condition. The most common result is “Unlocked,” which means your phone is not tied to any carrier and can be used with any compatible SIM card worldwide. This is ideal if you’re planning to switch networks or travel.

If the result shows “Locked” or “In contract,” your phone is still restricted to the original carrier. This usually means you haven’t finished paying off the device or it’s under a service agreement. These phones cannot be used with a different SIM until they meet unlock requirements.

A more serious status is “Blacklisted.” This means the device has been reported as lost, stolen, or involved in fraud. Blacklisted phones won’t work on most networks in the U.S. and internationally. It’s best to avoid buying any phone that returns this status.

Network-Specific IMEI Codes

Each major carrier may use different terminology in their IMEI reports. For example, AT&T uses terms like “Clean” and “Financed.” A “Clean” IMEI means the device is not reported lost or stolen and may be eligible for unlocking. If the phone is “Financed,” it usually means it’s still being paid off and may not be unlockable until the balance is cleared.

T-Mobile may show “SIM Unlock Eligible” in your account or the Device Unlock App. This means your device meets the basic unlock conditions and can likely be permanently unlocked once requested.

With Verizon, most devices sold after July 2019 are automatically unlocked after 60 days of activation. In many cases, Verizon phones show as “Already unlocked,” especially for postpaid accounts. This simplifies the process, but it’s still a good idea to verify using your IMEI if you’re unsure.

Common Problems & Fixes After Unlocking

Even after unlocking your phone, you might run into a few hiccups. These are usually easy to fix, but knowing what to expect can save you time and frustration.

“SIM Not Supported”

If you insert a new SIM card and see a “SIM Not Supported” or similar message, don’t panic. This usually means the phone hasn’t fully recognized the new network yet.

First, try restarting your device. A simple reboot can trigger a network refresh. Next, check if your phone needs a carrier settings update—these are often prompted automatically but can also be triggered manually in your phone’s settings. If the issue continues, double-check your IMEI unlock status using an online tool or by contacting your carrier to ensure the unlock was processed correctly.

Phone Still Locked After Unlock Request

Sometimes you follow all the steps, but the phone still appears locked even after your unlock request has been approved. In this case, the unlock may not have been fully processed yet.

Start by checking your IMEI again with your carrier’s tool or a trusted IMEI checker to confirm the current status. If it still shows “locked,” reach out to carrier support and provide your case or request number. Many carriers note that it can take 24 to 48 hours for the unlock to be fully completed on their backend—even after confirmation emails are sent.

Unlock Worked but No Signal

If your phone accepts the new SIM and shows it’s unlocked but doesn’t get a signal, the issue might be with network compatibility.

In some cases, the phone’s band or frequency may not match those used by your new carrier. This is especially common when switching between GSM and CDMA networks or using international phones. You might also need to manually update or enter your carrier’s APN (Access Point Name) settings so the phone can connect to the network properly. If you’re unsure what settings to use, check your carrier’s website or contact their tech support for help configuring your device.

How Do I Know If I Own My Phone (Fully Paid or Not)?

Knowing whether you truly own your phone can make a big difference—especially when it comes to unlocking it or switching carriers. If your device is still under a payment plan or contract, it may be locked or ineligible for unlock. Here’s how to find out where you stand.

IMEI Status Tells You a Lot

Your phone’s IMEI number can reveal key details about ownership and financial status. When you run an IMEI check using a carrier tool or a trusted IMEI website, look for terms like “Financed” or “Under contract.” These usually mean you’re still making payments on the phone, and you don’t yet fully own it. Carriers often restrict unlocks for these devices until the final bill is paid.

On the other hand, if the report shows “Paid in full” or “No contract,” then the device is considered yours. In most cases, that also means it qualifies for unlocking. Be cautious if the IMEI report includes a “blacklist” or “lost/stolen” status. This often means the phone was reported as missing or involved in fraud, which disqualifies it from being unlocked—regardless of payment status—and could lead to service issues.

Carrier Account Check

Another reliable way to confirm if you own your phone is by logging into your wireless account. Whether you’re with AT&T, T-Mobile, Verizon, or another carrier, go to the billing or device section of your account dashboard. There, you can usually see:

• The current balance on your installment plan (if any)
• Whether your device is still under contract
• Upgrade eligibility or trade-in options

If the balance shows $0 and your contract term is marked complete, that means your phone is fully paid off and you officially own it. You can now move forward with unlocking it, trading it in, or using it with another carrier of your choice.

Extra Tips for Buying or Selling a Used Phone

Whether you’re buying a secondhand phone or selling your old one, taking a few extra steps can help you avoid costly mistakes. A quick IMEI check can protect you from scams, hidden locks, or blacklisted devices.

Always Check IMEI Before Purchase

Before you hand over any money for a used phone, always ask the seller for the device’s IMEI number. This is the most reliable way to check whether the phone is unlocked, paid off, and not reported lost or stolen. Once you have the IMEI, run it through a trusted IMEI checker or use the carrier’s unlock tool to verify:

• Unlock status
• Blacklist status
• Financing or contract obligations

If anything looks suspicious—like the phone still being financed or flagged as lost—it’s best to walk away from the deal.

Don’t Rely on Seller’s Word

Even if the seller promises the phone is “unlocked” or “paid off,” you should always verify the status yourself. Scammers often list locked or blacklisted phones on marketplaces like eBay, Craigslist, or Facebook at low prices to lure buyers. If a deal looks too good to be true, it probably is.

Instead, buy from reputable sellers, ask for proof of ownership, and double-check everything before completing the purchase. A few extra minutes of caution can save you from ending up with a useless or locked device.

Legal and Safety Considerations

Unlocking your phone using the IMEI number is not only a practical move—it’s also legal in the United States, as long as certain rules are followed. But with that freedom comes the need to stay cautious, especially when navigating the online world of unlock services.

Is It Legal to Unlock With IMEI?

Yes, unlocking your phone using the IMEI is fully legal in the U.S. thanks to a 2014 ruling by the Federal Communications Commission (FCC). This ruling gave consumers the right to unlock their phones, especially after their contracts or payment plans are fulfilled. However, legal unlocking still depends on your carrier’s policies.

Most carriers require the phone to be fully paid off, not reported lost or stolen, and active for a minimum number of days before they’ll unlock it. Once those conditions are met, they’re obligated to provide the unlock—usually free of charge.

Beware of Fake Unlock Services

While unlocking is legal, not all services that claim to unlock your phone are safe or legitimate. There are countless websites and YouTube videos that offer “instant unlock codes” or “magic apps” that promise to unlock your phone using your IMEI. Many of these are scams.

You should never pay for an unlock code or service without checking if the source is reputable. Avoid any site that asks for upfront payment without showing you verification, reviews, or a clear refund policy. Be especially wary of so-called “code generators” or sketchy APK files—these often contain malware or don’t work at all.

The safest way to unlock is still through your carrier or a verified unlock provider with good customer feedback. Always read the fine print and check IMEI eligibility before using any third-party service.

Final Recap – Quick Checklist

To quickly find out if your phone is unlocked, start by dialing *#06# to get your IMEI number. Use your carrier’s website or a trusted IMEI checker to confirm unlock status. If you’re using an iPhone, look for “No SIM restrictions” in the settings. For Android devices, insert a SIM from a different carrier and see if it connects. Always check unlock status before switching networks, selling, or buying a used phone to avoid surprises.

Frequently Asked Questions (FAQs)

Q1: What is the fastest way to check unlock status with IMEI?
The quickest method is to dial *#06# to get your IMEI number, then enter it into your carrier’s official unlock portal (like AT&T or T-Mobile) or use a trusted IMEI checker website. These tools usually give instant results.

Q2: Is using an IMEI checker safe?
Yes, as long as you use reputable websites like IMEI.info, Swappa, or your carrier’s own tool. Avoid sketchy websites that ask for payment upfront or don’t use secure (HTTPS) connections.

Q3: Can I unlock my phone myself using IMEI?
Not directly. You’ll need to request an unlock through your carrier, who uses the IMEI to process it. Some third-party services can assist, but they should be used with caution and only if you trust the source.

Q4: What if the IMEI says “locked” but my SIM still works?
In some cases, the phone may be locked but still compatible with the new carrier’s network. However, if the carrier ever updates their restrictions or detects the mismatch, service could be disrupted.

Q5: Can I use eSIM if the phone is locked?
Only if the eSIM is from the same carrier the phone is locked to. A locked phone will reject eSIMs from other networks until it’s officially unlocked.
