I Bought a Locked iPhone - How Do I Unlock It? [2026 Guide]

If you bought a locked iPhone, the first step is to identify what type of lock it has. A screen passcode can usually be removed by erasing the device, while Activation Lock requires the previous owner's Apple Account, Apple's support process, or another supported solution. A carrier lock must be handled by the carrier, while an MDM lock may require the organization that manages the device.

This guide explains how to identify each lock and what you can do next if you bought an iPhone that is locked.

Quick Answer: What to Do If You Bought a Locked iPhone

Not every locked iPhone needs the same solution. Check what appears on the screen first.

What You See	Lock Type	What You Should Do
Passcode screen, iPhone Unavailable, or Security Lockout	Screen Lock	Ask the seller to erase it, restore the iPhone, or use an iPhone unlocking tool
"iPhone Locked to Owner"	Activation Lock	Contact the previous owner, request Apple support, or check a supported removal option
Someone else's Apple Account is still signed in	Apple Account Lock	Ask the previous owner to sign out and remove the device
"SIM Not Supported" or another carrier does not work	Carrier Lock	Contact the carrier that locked the iPhone
Remote Management during setup	MDM Lock	Contact the previous organization or use an authorized MDM removal option
Lost Mode or an owner message	Lost/Stolen Device	Stop setup and contact the seller, owner, or marketplace

Apple specifically recommends that buyers do not take ownership of a used iPhone with Activation Lock enabled. If an online purchase arrives at the "iPhone Locked to Owner" screen, Apple's guidance is to return it.

What Kind of Lock Does the iPhone You Bought Have?

Before trying to unlock the device, determine which restriction you are actually dealing with.

1. Screen Passcode Lock

A screen lock appears before you can access the Home Screen. You may see Enter Passcode, iPhone Unavailable, or Security Lockout.

Removing a forgotten screen passcode normally requires the iPhone to be erased. Apple provides both on-device and computer-based reset options, while third-party iPhone unlockers can provide another guided desktop workflow. However, there is an important catch with a second-hand iPhone: removing the screen passcode does not remove Activation Lock.

If Find My is still connected to the previous owner's Apple Account, the phone may display iPhone Locked to Owner after you erase and reactivate it.

2. Activation Lock / iPhone Locked to Owner

If you see iPhone Locked to Owner during setup, the device is still linked to the previous owner's Apple Account.

Activation Lock is part of Find My and remains associated with the device even after it has been erased. Apple recommends asking the previous owner to remove the iPhone from their account before you take ownership. This is one of the most important lock types to check when buying a used iPhone.

3. Apple Account Lock

Sometimes the iPhone is already activated, but the previous owner's Apple Account is still signed in under Settings. This can prevent you from turning off Find My, signing out of the Apple Account, or fully erasing and setting up the device as your own. The safest solution is to have the previous owner sign out and remove the iPhone from their account before you continue using it.

4. Carrier Lock

A carrier-locked iPhone can work normally but may only accept SIM cards or eSIMs from a specific carrier.

To check Settings > General > About > Carrier Lock. If you see No SIM restrictions, the iPhone is carrier-unlocked. Apple states that Apple cannot remove a carrier lock. Only the carrier that locked the iPhone can unlock it.

5. MDM or Remote Management Lock

If Remote Management appears while setting up the iPhone, the device may still be enrolled in a company's, school's, or other organization's Mobile Device Management system. For a legitimately purchased device, contact the seller or previous organization first and ask them to release the phone from management.

A third-party MDM removal solution may help with certain locally applied restrictions on a device you own or are authorized to manage, but organization-side enrollment can sometimes return after the phone is erased.

Bought an Activation-Locked iPhone? Try These Solutions First

Activation Lock is usually the most serious issue when buying a second-hand iPhone because simply factory-resetting the device does not remove the previous owner's account association. Try the following options in order.

Way 1. Ask the Previous Owner to Remove Activation Lock

If you can still contact the seller, this is the best solution. The previous owner can either enter their Apple Account credentials directly on the iPhone or remove the phone remotely.

• Step 1. Sign in to iCloud Find Devices with the Apple Account linked to the iPhone.
• Step 2. Select the locked iPhone.
• Step 3. Choose Remove.
• 

Apple confirms that a device can be removed from the previous owner's account through Find My, including remotely in supported situations. After the account association is removed, restart the setup process.

Way 2. Ask Apple to Remove Activation Lock with Proof of Purchase

If you cannot contact the previous owner but have valid purchase documentation, Apple provides an official Activation Lock support request. Apple currently states that users who need help removing Activation Lock and have proof of purchase documentation can start a support request.

This is especially worth trying if you purchased the device from a legitimate retailer, or reseller and can prove ownership.

What you may need

• Keep your purchase receipt and device information available when submitting the request.
• Apple decides whether the documentation meets its requirements.

Way 3. Remove Activation Lock with TunesKit iPhone Unlocker on Supported Devices

If the official options are unavailable and the iPhone belongs to you, TunesKit iPhone Unlocker provides an additional Activation Lock removal mode for supported older devices.

Instead of using the separate jailbreak-based workflow described in the old version of this article, the current TunesKit iPhone Unlocker includes Remove iCloud Activation Lock directly and does not require jailbreaking. This feature supports iPhone 5s through iPhone X running iOS 12.0–16.7.15. This limitation should be checked before downloading or purchasing the software.

• Step 1. Connect the supported iPhone to a Windows PC or Mac and launch TunesKit iPhone Unlocker.
• Step 2. Choose Remove iCloud Activation Lock.
• Step 3. Check the device information and follow the on-screen instructions to complete the process.

Bought an iPhone with a Screen Passcode? 3 Ways to Unlock It

If the phone only has a screen passcode, there are more options. Keep in mind that all normal screen-passcode removal methods erase the existing data on the iPhone. For a second-hand device, that is usually appropriate because the previous owner's personal data should not remain on the phone.

Way 1. Ask the Seller to Erase the iPhone

If the seller is available, ask them to unlock and erase the device before you use it. This is also the safest way to determine whether Activation Lock is still enabled.

Apple recommends that a preowned iPhone be erased before ownership is transferred. When setup begins, it should eventually reach a usable Hello screen without requesting the previous owner's Apple Account.

If it asks for the previous owner's account after erasing, you are dealing with Activation Lock rather than only a screen passcode on this iPhone.

Way 2. Restore the Locked iPhone with Apple Devices or Finder

If you cannot enter the passcode, Apple allows you to put the iPhone into recovery mode and restore it from a computer.

On a Windows PC

• Step 1. Connect the locked iPhone to your PC.
• Step 2. Put the iPhone into recovery mode using the correct button combination for your model.
• Step 3. Open Apple Devices on the computer and select the iPhone.
• Step 4. Choose Restore iPhone.
• 

On a Mac

• Step 1. Connect the iPhone and place it in recovery mode.
• Step 2. Open Finder and select the iPhone under Locations.
• Step 3. Choose Restore when prompted.
• 

Apple currently recommends Finder on Mac and Apple Devices on Windows for this recovery process. iTunes remains relevant mainly on older supported systems. Restoring erases the iPhone and installs the current iOS software.

Way 3. Unlock the Screen with TunesKit iPhone Unlocker

If you prefer a guided desktop program, TunesKit iPhone Unlocker can remove several types of iPhone screen locks, including 4-digit and 6-digit passcodes, Touch ID, Face ID, disabled screens, and iPhone Unavailable situations.

How to Unlock the Bought iPhone

• Step 1. Install TunesKit iPhone Unlocker on your PC or Mac and connect the locked iPhone. Choose Unlock iOS Screen and click Start.
• Step 2. Follow the instructions to put the iPhone into the required mode. Confirm the detected device information and download the appropriate firmware package.
• Step 3. Click Unlock and wait until the screen passcode is removed.
•

Bought a Carrier-Locked iPhone? Contact the Carrier

A carrier lock is different from an iPhone passcode or Activation Lock. The phone itself may work normally, but you cannot use it with another mobile network.

First go to Settings > General > About > Carrier Lock. If it displays No SIM restrictions, the iPhone is already unlocked. If it is locked, contact the carrier associated with the phone and ask whether it is eligible for unlocking.

Apple clearly states that only the current carrier can unlock an iPhone for use with another carrier. Processing may take several days depending on the carrier. Avoid assuming that an online "carrier unlock" service can override the carrier's eligibility requirements.

---

Bought an MDM-Locked iPhone?

If you see Remote Management during Setup Assistant, the iPhone may still belong to or remain enrolled with a company, or another organization. The best solution is to ask the seller or organization to release it from their management system.

For a device you legally own or are authorized to manage, TunesKit iPhone Unlocker also includes an MDM removal feature that the current product page describes as removing MDM restrictions without requiring administrator credentials or erasing existing device data.

However, removing a local restriction does not always remove an organization-side enrollment assignment. If Remote Management returns after an erase, contact the previous organization.

---

What If the Seller Won't Respond?

If you bought a locked iPhone and the seller disappears, do not immediately assume every lock can be removed with software. Your next step depends on where you bought the phone.

If You Bought It from an Online Marketplace

Open a return, refund, or buyer-protection claim as soon as possible if the device was advertised as usable or unlocked but arrived locked.

Save:

• The original product listing
• Messages with the seller
• Payment records
• Photos of the lock screen
• Serial number or IMEI shown on the device or packaging

For an iPhone that arrives with Activation Lock, Apple's own preowned-device guidance recommends returning an online purchase rather than taking ownership of the locked device.

If You Have Valid Proof of Purchase

Consider an Apple Activation Lock support request when applicable.

If the iPhone Is in Lost Mode

If you see an owner's message, contact information, or other indications that the device was lost, do not try to erase or resell it. Contact the seller, marketplace, or rightful owner.

Can You Unlock a Bought iPhone Without the Previous Owner?

Sometimes. It depends entirely on the type of lock.

Lock Type	Can It Be Solved Without the Previous Owner?	Main Limitation
Screen Passcode	Usually yes	The iPhone must be erased; Activation Lock may appear afterward
Activation Lock	Sometimes	Apple may require proof of purchase; third-party compatibility is limited
Apple Account Lock	Limited	Previous owner's account may still control Find My
Carrier Lock	Yes, if eligible	Only the carrier can approve the unlock
MDM Lock	Sometimes	Organization-side enrollment may remain
Lost Mode	Not appropriate to bypass	Contact the owner, seller, or platform

This is why identifying the lock before paying for an unlocking service or software is essential.

How to Avoid Buying a Locked iPhone Next Time

Before paying for a used iPhone, verify that the seller has fully prepared the device for a new owner. Apple recommends checking that the phone has been erased and is no longer linked to the previous owner's Apple Account. If you see iPhone Locked to Owner, do not complete the purchase.

A practical pre-purchase check is:

• 1. Ask the seller to erase the iPhone.
• 2. Begin the setup process and confirm that it does not request the previous owner's Apple Account.
• 3. Check Settings > General > About > Carrier Lock if you need an unlocked carrier device.
• 4. Confirm the IMEI/serial information matches the device and purchase documentation.
• 5. If the phone belonged to a company or school, verify that Remote Management no longer appears.

An iPhone that reaches setup normally without a previous owner's account request is far safer to purchase than one sold while still passcode-locked.
