Introduction
You just bought a second-hand iPhone, but when you turn it on, you find yourself stuck at the iCloud Activation Lock screen. Such a situation can be irritating a buyer. Activation Lock is Apple's anti-theft mechanism that binds a device to the Apple ID of the previous owner, meaning you cannot use the phone until the account is removed.
This article explains what Activation Lock is and how to bypass iCloud activation lock. We'll show you some simple methods to unlock the device. If they fail, you can always get help from a tool such as Dr.Fone – Screen Unlock (iOS). Let’s explore further!

What Is iCloud Activation Lock — and Why Does It Appear?
iCloud Activation Lock is a security feature in-built in iPhones which automatically gets activated once Find My iPhone is enabled on a device. The main reason for this is to protect the phone in case it is lost or stolen. Usually, the lock gets triggered when a phone is factory reset, a new OS is installed or user signs out without disabling Find My iPhone first.
So basically a lock is not internally indicating that your handset has stopped working. What it's really implying is, the gadget is still tagged with the Apple ID belonging to the original owner. Generally, the warning is something like “iPhone Locked to Owner” or it's a asking screen for the previous owner's Apple ID and password.
Contact the Seller First
The very first thing you need to do is to contact the seller. Request him/her to disassociate the iPhone from their Apple ID. They can perform this online by logging in to icloud.com → Find My → selecting the device → Erase iPhone.

Another way is to remove it via their iPhone by going to Settings → Apple ID → selecting the device → Remove from Apple Account.

This method is the most straightforward and quickest to resolve Activation Lock, if the seller agrees. Preserve all communications and receipts as these may be required if the phone is found to be stolen.
Contact Apple Support with Proof of Purchase
Apple might help unlock your gadget if you present the necessary papers. Provide any document proving your legitimate ownership of the iPhone, for example, the original purchase receipt, a purchase document, or the box with the IMEI or serial number. Also, you may note down the serial number that is displayed on the Activation Lock screen.
In order to get help or enquire about the unlocking procedure, you can contact Apple through apple.com/support or walk into an Apple Store that is near you. However, you should keep in mind that the entire unlocking process may take several days and if your evidence is not really convincing, then Apple may even refuse to unlock your device.
Check If the Device Is Reported Stolen

Don't start by investing time or money on the iPhone without first checking if the device was reported stolen. Dr.Fone – Online Unlock is an online IMEI checker that can help you out and show you whether the phone is blacklisted for free.
Don't go any further if the IMEI revealed that the device was stolen. Unlocking it will be useless. Contacting the police would be the best solution.
