Our Top 5 Picks – What You Need to Know About SIM Network Unlock PINs
A SIM Network Unlock PIN lets you use your phone with any compatible carrier worldwide.
You can get the unlock PIN for free if your device meets your carrier’s eligibility rules.
AT&T, T-Mobile, and Verizon each have different unlock methods—know your provider’s process.
Android phones usually prompt for a 16-digit unlock code, while iPhones unlock remotely via servers.
Avoid third-party unlock scams—always start with your carrier’s official unlock request tool.
A SIM Network Unlock PIN is a special code used to unlock a mobile phone from the carrier it was originally tied to. When you insert a SIM card from a different carrier into a locked phone, the device asks for this PIN to grant access to the new network. Carriers like AT&T, T-Mobile, and Verizon lock phones they sell to ensure users stay on their network for a certain period. But once you meet their requirements—like paying off the phone or completing a contract—you can request this unlock PIN for free. The method to get the PIN depends on your carrier, phone model (Android or iPhone), and whether the device is eligible. Some Android phones (like Samsung) show a “SIM Network Unlock PIN” prompt directly, while iPhones display messages like “SIM Not Supported.” Unlocking can be done through the carrier’s website, customer service, or sometimes via a pre-installed unlock app.
TL;DR – What is a SIM Network Unlock PIN?
A SIM Network Unlock PIN is a code that lets you remove your phone’s carrier lock so you can use it with other networks. It’s usually free if your device is eligible—paid off, not stolen, and active for a certain period. AT&T and T-Mobile offer 16-digit unlock codes, while Verizon unlocks most phones automatically after 60 days. Android users enter the code manually; iPhone users are unlocked via Apple servers. Always request your code from the carrier, avoid sketchy unlock apps, and know your rights before buying or selling a locked device.
What Is a SIM Network Unlock PIN?
A SIM Network Unlock PIN is a unique code used to release your phone from its original carrier’s network restrictions. When a phone is “network locked,” it can only accept SIM cards from the carrier that sold the device. This type of lock is common with phones purchased through installment plans or bundled contracts, especially from carriers like AT&T, T-Mobile, and Verizon. The SIM Network Unlock PIN becomes necessary when you try to insert a SIM card from a different network—for example, when switching carriers, traveling abroad and using a local SIM, or selling your phone to someone who uses another provider.
It’s important not to confuse the SIM Network Unlock PIN with other codes like the SIM PIN, which protects the SIM card from unauthorized use, or the PUK code, which is used to unlock a blocked SIM after too many wrong PIN attempts. The Network Unlock PIN is specifically related to the device’s restriction, not the SIM card itself.
Phones get locked to a carrier mainly for business reasons. Carriers subsidize the cost of phones, so they lock the device to ensure you stay with their service until your agreement is fulfilled. Once those conditions are met—like fully paying off the phone or keeping the account in good standing for a certain period—you can request the unlock code, and use your device freely across compatible networks.
What is the SIM Network Unlock PIN for AT&T?
AT&T locks most of the phones it sells, especially those purchased through financing or included in contract-based promotions. This lock prevents the phone from being used with any other carrier’s SIM card until certain conditions are met. If you try to use a non-AT&T SIM in a locked phone, you’ll likely see a message saying “SIM network unlock PIN” or “Enter network unlock code.” This prompt is your phone asking for AT&T’s 16-digit unlock code to remove the restriction.
To unlock your AT&T device, the safest and most reliable method is using the AT&T Device Unlock Portal. This online tool allows both AT&T customers and non-customers (like secondhand phone buyers) to submit an unlock request. You’ll need your device’s IMEI number (dial *#06# on your phone), and the process typically takes 1 to 2 business days for approval.
To qualify for a free unlock code from AT&T, the device must:
Be paid off in full (including installments)
Have been active on AT&T’s network for at least 60 days
Not be reported lost, stolen, or associated with fraud
Be associated with an account in good standing (if you’re a current AT&T user)
Once approved, AT&T will email you the 16-digit unlock code (for Android phones) along with step-by-step instructions. For iPhones, the unlock is completed remotely through Apple’s servers—there is no code to enter manually. Simply insert a SIM card from another carrier and restart the device after the unlock is processed.
Unlocking your AT&T phone using the official method is completely free if you meet the eligibility requirements, and it ensures your phone can be used globally or resold without carrier limitations.

What is the SIM Network Unlock PIN for T‑Mobile?
T‑Mobile typically locks devices sold under its financing plan or promotional offers to ensure service compliance. When you insert a non‑T‑Mobile SIM into a locked phone, you may be prompted with a message such as “SIM network unlock PIN” or “Enter network unlock code.” This code, often 16 digits long, is what removes the network restriction.
For Android devices, T‑Mobile offers a convenient Device Unlock App that may already be installed. Simply launch the app, follow the on‑screen steps, and if your phone is eligible, the network lock can be lifted without requiring a manual code.
If the app isn’t available or the unlock is unsuccessful, you can contact T‑Mobile support via chat, phone, or in-store. Provide your IMEI number (dial *#06#) and request the SIM Network Unlock PIN. They will check eligibility and, if approved, either send the code directly or assist you in unlocking the device.
T‑Mobile provides a 16‑digit network unlock code free of charge once your phone meets these criteria: the device must be fully paid off or otherwise eligible (e.g., no outstanding installment plan), active on the network for a minimum period (usually 40 days), and not reported lost, stolen, or involved in fraud. Once approved, you’ll receive the unlock code—typically via email or SMS—and T‑Mobile’s support team will walk you through the process if needed.
What is the SIM Network Unlock PIN for Verizon?
Verizon’s SIM network unlocking policy is quite different from most other carriers. Since July 2019, Verizon automatically unlocks most 4G LTE and 5G devices after just 60 days of activation—which means you likely won’t see a “SIM Network Unlock PIN” prompt unless you’re using an older device or one under special restrictions. In general, postpaid Verizon phones are unlocked automatically and do not require a PIN to switch to another carrier.
However, there are exceptions to this rule:
Prepaid Verizon devices often come locked for up to 60 days after activation. After that period, they too are unlocked automatically—no action required.
Older CDMA-only phones (like those before the 4G LTE era) may still be locked and could prompt you for a SIM network unlock code.
If a device has been flagged for fraud, theft, or payment issues, Verizon may keep it locked and you’ll need to contact support to resolve the issue.
To check if your Verizon device is locked or unlocked, simply insert a SIM card from another carrier. If your phone connects to the new network without any popups or restrictions, it’s already unlocked. If it asks for a SIM Network Unlock PIN, you’ll need to contact Verizon customer support for verification.
As for the idea of a Verizon 16-digit network unlock code, this is often misunderstood or misused online. Verizon rarely provides manual unlock codes since most devices are unlocked automatically. Any “free unlock code generators” claiming to provide Verizon codes should be avoided—they’re often scams or malware in disguise. The safest approach is always to let the 60-day automatic unlock window pass or contact Verizon directly if you believe your device should be unlocked but isn’t.
In summary, most Verizon customers never need a SIM unlock PIN, but if you do, the unlock process is free and handled entirely through Verizon support—no code needed in most cases.
Device-Specific Breakdown: Unlock PIN for Android vs iPhone
What is a SIM Network Unlock PIN on Android Devices?
On Android phones, the SIM network unlock PIN is a prompt that appears when a phone is locked to a specific carrier, and you insert a SIM card from another network. Brands like Samsung, Motorola, and Google Pixel all handle this similarly, though the wording might vary slightly. You’ll typically see a message like “SIM network unlock PIN,” “Network unlock code,” or “Enter unlock code” immediately after inserting the new SIM.
The input screen usually appears on boot or right after SIM detection. You’re required to enter the correct unlock PIN—often a 16-digit code provided by your original carrier. If you enter the wrong PIN multiple times (usually more than 5–10 tries), the phone might temporarily freeze the SIM slot, require a Master Unlock Code, or even hard-lock the device, meaning only the carrier can now unlock it.
Some tools and apps online claim to provide free SIM network unlock PINs for Android, but users should proceed with caution. While some community forums or device-specific tools (like Samsung Z3X or ChimeraTool) might work for older models, most “free unlock APKs” found online are either scams or unsafe. Your best route is always through the carrier or using a legit third-party unlock service that works via IMEI.

What is a SIM Network Unlock PIN for Samsung Phones?
Samsung devices have a specific network lock prompt that often reads: “Enter Network Lock Control Key.” This is just Samsung’s version of the SIM network unlock PIN. When you insert a SIM card from a different carrier, this message will appear if the device is locked.
Samsung phones are particularly known for their carrier firmware customizations. A Samsung Galaxy bought from AT&T, for instance, may come with AT&T-specific firmware, branding, and network restrictions. These phones usually require a carrier-issued 8- or 16-digit unlock code, and the process is device-model dependent.
It’s also essential not to confuse OEM unlocking (found in Developer Options) with SIM unlocking. OEM unlock is used for unlocking the bootloader, which is completely unrelated to SIM restrictions and is more about rooting or flashing custom ROMs. If you’re trying to use your Samsung phone with another carrier, you need a SIM network unlock code, not bootloader access.
What is a SIM Network Unlock PIN on iPhone?
iPhones handle network locks differently than Android devices. Instead of prompting for a SIM network unlock PIN, iPhones display the message “SIM Not Supported” when a non-compatible SIM is inserted into a locked device. The phone won’t allow access to the network until it’s unlocked.
That’s because the iPhone unlock process is server-based, not code-based. Apple and the carrier manage the lock status through Apple’s activation servers. When you request an unlock, the carrier communicates with Apple, and once approved, your iPhone is marked as “unlocked” in Apple’s database.
After approval, all you have to do is insert a new SIM card and restart the device—or sometimes connect to Wi-Fi or iTunes to complete the activation. If your iPhone still shows “SIM Not Supported” even after approval, you may need to back up, erase, and restore the device.
Also note: Activation Lock (tied to the Apple ID/iCloud) is completely different from SIM locking. Even an unlocked iPhone won’t work if Activation Lock is enabled and you don’t have the Apple ID password. Only the original owner can remove that.
In summary, iPhones don’t use a visible SIM unlock PIN—everything happens behind the scenes via Apple’s system. If you see an unlock prompt, it’s likely not from the network but from iCloud’s Activation Lock.
How to Get a SIM Network Unlock PIN for Free
Getting a SIM Network Unlock PIN for free is easier than ever—if your phone meets your carrier’s eligibility requirements. Most U.S. carriers like AT&T, T-Mobile, and Verizon provide free unlock codes once your device qualifies. The best place to start is always the official carrier website. They typically offer an online unlock portal where you can enter your device’s IMEI number to check eligibility and submit a request.
To qualify for a free SIM unlock PIN, your phone usually needs to meet a few common conditions:
No active contract: If your phone was purchased under a contract, it must be completed or terminated early with all dues paid.
Device paid in full: Whether you bought it outright or financed it, the balance must be zero. Installment plans must be completed.
Not reported lost or stolen: Phones listed as blacklisted or flagged for fraud won’t be eligible for unlocking under any circumstances.
Active on carrier’s network for a set period: Most carriers require the device to be active for at least 40–60 days, depending on whether it’s a prepaid or postpaid account.
Once your phone meets the criteria, you can usually unlock it without paying a fee. Just submit your request online or through customer support. For example, AT&T’s unlock portal lets even non-customers request an unlock, while T-Mobile allows Android users to use the Device Unlock App directly.
If your device is still under contract or on an installment plan, you may have to pay an early unlock fee or finish paying off the device first. Some carriers make exceptions for military personnel or customers traveling internationally—so it’s worth asking.
Always avoid shady third-party websites promising free unlocks without eligibility checks. If your device qualifies, the carrier is legally obligated to unlock it for free—no tricks or fees required.
Bonus Tips – Free 16-Digit Network Unlock Code for Major Carriers
Unlocking your phone with a 16-digit SIM network unlock code is a common method, especially on Android devices from carriers like AT&T and T-Mobile. Below are key tips for getting these codes for free—directly from your carrier, with no fees or shady services involved.
AT&T 16-Digit Unlock Code for Free
To receive a free 16-digit unlock code from AT&T, your phone must meet their unlock policy conditions. These include:
The device must be paid in full
It must have been active on AT&T’s network for at least 60 days
It can’t be flagged as lost, stolen, or involved in fraud
It must not be under a current contract or installment plan
You can submit your request through the AT&T Device Unlock Portal. You’ll need your IMEI number (dial *#06# to find it) and a valid email address.
Once submitted, AT&T typically responds within 24 to 48 hours. If approved, you’ll get an email with your 16-digit SIM network unlock code and instructions. Be sure to follow the input steps carefully, especially for Samsung or Motorola devices.
If you’ve entered the code incorrectly multiple times, you might see an error message like “You’ve tried too many times.” In this case, the device could become temporarily or permanently locked, and only AT&T support can reset your unlock attempts. So double-check your code before entering it.
T-Mobile 16-Digit Unlock Code for Free
T-Mobile handles most unlocks via the T-Mobile Device Unlock App, available on many Android models. If your phone doesn’t support the app—or if it’s not working—you can still get a 16-digit unlock code by contacting T-Mobile support.
Before unlocking, make sure to:
Back up all data, as some devices may reset during the process
Check that the phone has been active for at least 40 days on a T-Mobile account
Ensure the device is fully paid off and not reported lost or stolen
To request your unlock code, use T-Mobile’s live chat or customer support line. Once verified, they will either push the unlock remotely (via app or server) or email you the 16-digit code with step-by-step instructions.
Note: Not all T-Mobile phones need or support a manual code—some are unlocked remotely after you meet the requirements.
Verizon 16-Digit Unlock Code for Free
For most modern Verizon phones, a SIM network unlock code isn’t required. Verizon automatically unlocks postpaid devices after 60 days from purchase, as long as they’re not flagged for fraud or theft.
However, there are a few cases when you might need a 16-digit unlock code, such as:
Legacy devices (older 3G/CDMA phones or early LTE models)
Certain prepaid Verizon phones, which may remain locked for 60 days
If a device doesn’t unlock automatically after the waiting period
If your phone asks for a SIM network unlock PIN and you’re on Verizon, it’s best to contact Verizon customer support. They can verify your device status and, if applicable, provide the necessary unlock code for free.
If your Verizon phone is still locked after 60 days, make sure your account is in good standing and the device is not blacklisted. Sometimes, a manual unlock request may be needed, especially for phones purchased through third-party retailers or during special promotions.
Getting a 16-digit network unlock code from your carrier is usually fast and free—as long as your phone is eligible. Avoid code generators or paid unlock sites when the safest solution is just a phone call or form away.
How to Unlock SIM Card Without Code (No Unlock PIN)?
If your phone is asking for a SIM Network Unlock PIN but you don’t have the code—or you’re trying to avoid entering one altogether—there are still a few reliable ways to unlock your SIM card without using a manual code.
Use Carrier Customer Service Tools
The safest and most recommended method is to contact your carrier directly. Most major carriers like AT&T, T-Mobile, and Verizon have online portals or support teams that can process an unlock request remotely. If you meet their eligibility requirements (phone paid off, active for 60+ days, not blacklisted), they may be able to unlock your phone without ever requiring you to manually enter a code. Some newer phones—especially iPhones—unlock in the background through the carrier’s system and Apple’s servers.
IMEI-Based Unlock (Official or Third-Party)
Another widely used method is an IMEI-based unlock, which is done by providing your phone’s IMEI number (dial *#06#) to an official carrier portal or a reputable third-party unlock service. In most cases, they’ll register your IMEI in a global unlock database, triggering the unlock remotely. This means you might never see the “Enter Unlock Code” screen at all—the phone just starts working with the new SIM after a reboot or reset.
SIM Unlock APKs (Use with Caution)
There are apps and APKs floating around the internet that claim to unlock your phone for free. These tools often promise to bypass the SIM network lock with root-level access or software exploits. Be extremely cautious. Many of these apps are outdated, don’t work with newer Android versions, or worse—contain malware. Unless you’re using a very old Android phone and understand the risks, this method is not recommended.
Factory Unlocked Devices = No Unlock PIN Needed
If you bought your phone unlocked directly from the manufacturer (like Samsung, Apple, or Google), it won’t be tied to any carrier and will accept any SIM card right out of the box. In this case, you’ll never need a SIM unlock PIN because the device isn’t network-restricted to begin with. You can switch SIM cards freely, even between international carriers.
eSIM Workaround (for Some Newer Phones)
Newer phones with eSIM support (like the iPhone 13, 14, or Samsung Galaxy S22/S23) offer a potential workaround. If your physical SIM slot is locked, but your eSIM is not—or if your carrier supports dual SIM flexibility—you may be able to activate service on an eSIM without needing to unlock the physical SIM slot. This only works in specific situations, depending on your phone model and carrier policy, but it’s worth exploring if you’re trying to avoid the SIM unlock process entirely.
In summary, unlocking your SIM card without a code is possible, especially through official carrier tools or IMEI-based services. Always start with your carrier’s support team, and avoid risky APK downloads unless you’re technically experienced and understand the consequences.

Common Issues and Fixes with SIM Unlock PIN
Unlocking your phone should be a smooth process, but sometimes errors or confusion around SIM Network Unlock PINs can get in the way. Here are some of the most common issues users face—and how to fix them quickly.
1. “SIM Network Unlock Unsuccessful” – What to Do
If you see the message “SIM Network Unlock Unsuccessful,” it usually means the code you entered was incorrect. This can happen if:
You typed the wrong unlock code
You used a code meant for a different device
The phone hasn’t been approved for unlocking yet
Fix: Double-check the unlock code provided by your carrier. Make sure it matches the exact IMEI number of your phone. If the code is correct and still doesn’t work, contact your carrier’s support—they may issue a new code or help reset your unlock attempts.
2. Reached Max Attempts? What Now?
Most phones only allow a limited number of unlock attempts—usually 5 to 10 tries. If you exceed this limit, the device may:
Lock itself permanently (hard lock)
Require a Master Unlock Code (MCK) or Defreeze Code
Need carrier-level reset via authorized service center
Fix: If you’ve hit the maximum attempts, stop trying immediately. Contact your carrier and explain the situation. They can provide the MCK code (if applicable) or walk you through the next steps, which may involve sending your device in for servicing.
3. Using the Wrong Carrier SIM for Testing
Another common mistake is inserting a SIM card that’s still compatible with the locked network, leading you to believe the phone is unlocked. Or worse, using a carrier that doesn’t support your phone’s network bands, causing signal issues even after unlocking.
Fix: When testing, use a SIM from a completely different carrier—preferably one that uses a different network (e.g., AT&T vs T-Mobile). This ensures that if your phone is truly unlocked, it will immediately detect the new SIM and request the unlock PIN or just connect.
4. When to Use PUK vs Unlock PIN
People often confuse the PUK (Personal Unblocking Key) with the SIM Network Unlock PIN, but they serve very different purposes:
The PUK code is used to unblock a SIM card that was locked due to too many incorrect SIM PIN entries. This is a security feature for your SIM card, not the phone.
The SIM Network Unlock PIN is used to unlock your phone from the carrier so it can work with other networks.
Fix: If your phone is asking for a PUK, contact your SIM card provider (not the phone manufacturer) to get the correct code. If it’s asking for a network unlock PIN, then you need to contact the original carrier that sold the device.
Understanding these common issues helps avoid permanent locks or wasted time. Always read error messages carefully, and if you’re unsure—pause and contact support before trying again.
Legal vs Illegal Unlocking – What You Should Know
Unlocking your phone is 100% legal in the U.S., thanks to protections put in place by the Federal Communications Commission (FCC). In 2014, the FCC issued a rule stating that carriers must unlock phones upon request, provided the customer meets certain eligibility criteria—like paying off the device or completing a contract. This rule ensures that consumers are not locked into one network forever and can switch carriers freely or use their phones internationally.
That said, not all unlocking methods are equal—and some can cross the line from legal to questionable.
Factory Unlock vs Carrier Unlock
A factory unlocked phone is sold without any network restrictions from the start. You can use it with any compatible SIM card around the world. These phones are typically more expensive but give you full freedom.
In contrast, a carrier unlock happens after purchase. If your phone was initially locked to AT&T, T-Mobile, or Verizon, it will require a SIM Network Unlock PIN or remote unlock request to free it. As long as the unlock is handled by the carrier (or with their permission), it is completely legal.
Risks of Using Third-Party Paid Unlock Services
There are hundreds of third-party websites offering unlock codes for a fee, often based on your IMEI number. While many are legitimate, others are scams or operate in a legal gray area. Some even obtain unlock codes through unauthorized methods or fake carrier credentials, which may violate your phone’s warranty or terms of service.
Key risks include:
Paying for a code that never arrives
Bricking your phone with a bad code
Getting locked out permanently by exhausting unlock attempts
Violating your carrier’s terms of service or device agreement
Best Practice: Always try the official unlock process first. Carriers are required to honor unlock requests (if eligible) and do not charge a fee. Only use paid services if your carrier won’t help—and only from reputable sources with positive reviews and refund guarantees.
In summary, unlocking your phone is legal and protected by U.S. law, but how you do it matters. Stick with carrier-approved methods whenever possible, and be careful about who you trust with your IMEI and money if you go the third-party route.
How to Check If Your Phone Is Already Unlocked
Before going through the trouble of requesting an unlock code or contacting your carrier, it’s smart to check if your phone is already unlocked. Many phones—especially newer ones—come unlocked out of the box or are automatically unlocked after a short period (like 60 days on Verizon or T-Mobile). Here are the easiest ways to find out:
1. Use a Different SIM Card and Test
The most reliable way to test your phone’s unlock status is to insert a SIM card from a different carrier.
Power off your phone.
Remove your current SIM card.
Insert a SIM from another network (e.g., use a T-Mobile SIM in an AT&T phone).
Turn the phone back on.
If your phone connects to the new network (you see signal bars and can make calls), it’s unlocked. If you see a message like “SIM Not Supported,” “Enter Network Unlock Code,” or “SIM Network Unlock PIN,” your phone is still locked.
2. Check in Phone Settings (iPhone and Android)
Some phones let you check unlock status through settings, though this isn’t always 100% accurate.
iPhone: Go to Settings > General > About. If you see “No SIM restrictions” under Carrier Lock, your iPhone is unlocked. If it says anything else, it’s still locked.
Android: This varies by brand, but you can try: Settings > Connections > Mobile Networks > Network Operators
If your phone lets you search and connect to other carriers, it may be unlocked.
Some Samsung models will show lock status under Settings > About Phone > Status > SIM card status.
3. Use an Online IMEI Checker Tool
You can use free or paid IMEI checking websites to see if your phone is locked or unlocked. These tools analyze your device’s IMEI (dial *#06# to find it) and return its lock status, warranty info, and more.
Examples include:
Note: Be cautious when using free IMEI sites. Some may collect data or upsell you paid services. Stick to well-reviewed or carrier-backed tools.
With these simple checks, you can confirm your phone’s unlock status in just a few minutes—saving time, effort, and frustration before attempting a carrier unlock.
Final Recap – SIM Network Unlock PIN Made Simple
Unlocking your phone with a SIM Network Unlock PIN isn’t as complicated as it once was. Thanks to updated FCC rules and more transparent carrier policies, most users can unlock their phones for free—as long as the device meets basic requirements like being paid off and not flagged as lost or stolen.
Your first step should always be the official carrier route. Whether it’s AT&T’s online portal, T-Mobile’s Device Unlock app, or Verizon’s automatic unlock policy, these methods are safe, legal, and usually hassle-free.
Stay away from shady “unlock APKs” or sketchy websites offering free unlock codes with no verification. Many of these are scams or may even damage your phone.
Lastly, know your rights before buying or selling a used phone. Always check its lock status and IMEI to avoid surprise restrictions later. A little research upfront can save you time, money, and frustration down the line.
Frequently Asked Questions (FAQs)
If you enter the wrong unlock PIN repeatedly (usually 5–10 times), your phone may become hard-locked, meaning it can no longer be unlocked with a regular code. Some devices will require a Master Unlock Code (MCK) from the carrier, while others may need to be sent in for servicing. Always double-check the code before entering it.
It depends on the carrier. Most will not unlock a device that still has an outstanding balance or is under a contract/financing plan. However, some carriers may make exceptions—for example, for military deployment or hardship situations. You’ll typically need to pay off the phone to be eligible for a free unlock.
Yes, once your phone is successfully unlocked, the change is permanent. You can switch SIM cards or carriers at any time without needing to re-enter a code. Even after a factory reset, the phone will remain unlocked.
No, unlocking your phone does not erase your data. The process simply removes the carrier restriction on your device. That said, it’s always a good idea to back up your data just in case something goes wrong—especially when using third-party tools or apps.
In some cases, yes—but only if the eSIM is not also locked by the original carrier. Some phones allow flexibility between physical SIM and eSIM usage. If your phone is locked and the eSIM is tied to the same carrier, you’ll still need to unlock the device to use another network.
Most unlock requests are processed within 24 to 48 hours, though some may take up to 3–5 business days, depending on your account status and device type. Once approved, you’ll receive the 16-digit unlock code (for Android phones) or a confirmation if it’s an iPhone (which is unlocked remotely through Apple’s servers).
