You pick up a used iPhone from eBay or maybe a liquidator, go to set it up, and suddenly—BAM. A screen pops up saying "Remote Management." It’s frustrating. It feels like you’ve been scammed or like the phone is basically a brick sitting in your palm. This isn't just a simple passcode lock; it's Mobile Device Management (MDM). Businesses and schools use this to control what happens on their hardware. If you're seeing this, it means the serial number is still enrolled in a company’s deployment program.
Can you actually fix it? Yeah, but it’s not always a one-click deal.
What is MDM and why is it on your phone?
MDM is basically a leash. Apple designed the Device Enrollment Program (DEP) so IT departments can blast settings, apps, and restrictions to thousands of devices at once without ever touching them. When you see that screen, the iPhone is reaching out to Apple’s servers, which then point it toward a specific corporate server. It says, "Hey, I belong to Coca-Cola or a random school district in Ohio."
Usually, this happens because an IT manager forgot to "release" the device from their Apple Business Manager (ABM) portal. It’s a clerical error that ruins your day.

The official way to remove remote management iPhone profiles
If you actually own the phone and have a receipt, the path of least resistance is talking to the original owner. This is the only way to make the removal permanent. If the IT department removes the serial number from their portal, the lock vanishes forever. You just restore the phone in iTunes or Finder, and it's a clean slate.
But let's be real. If you bought this from a guy on a street corner or a random warehouse, they probably won't help you. You're left holding a device that thinks it's still at the office.
Checking for local profiles
Sometimes you can actually get into the phone but find certain features are grayed out. In this case, the MDM isn't a hard lock at the "Hello" screen; it's just a profile installed in the settings. You can check this by going to Settings > General > VPN & Device Management. If there's a profile there, try to delete it. Often, though, it'll ask for a PIN you don't have. Or worse, the "Remove Profile" button is just... missing. That’s because the administrator flagged it as non-removable.

Using bypass tools (The "Gray" Area)
When the official route fails, people turn to software. There are a dozen programs out there like AnyUnlock, iMazing, or WooTechy iMover. They all basically do the same thing: they trick the setup process into skipping the MDM activation step.
Here is the catch. Most of these tools don't actually remove the device from the company's server. They just hide the lock locally. If you factory reset that iPhone again? The lock comes right back. It's a temporary bypass, not a permanent cure.
I’ve seen people use the iMazing method quite a bit. It involves backing up the phone, editing the backup files to "tell" the phone it has already passed the setup assistant, and then restoring that modified backup. It's clever. It works. But it’s tedious and requires a Mac or PC.
Why jailbreaking isn't the silver bullet anymore
Back in the day, jailbreaking was the go-to for everything. Nowadays? It’s harder. With newer versions of iOS, Apple has tightened the "Root" protections. While some checkm8-based jailbreaks (for older devices like the iPhone X and below) can help suppress MDM files, it's overkill for most people. Plus, you lose the ability to use banking apps or Netflix easily. It’s a trade-off that usually isn't worth the headache just to get around a corporate lock.
The reality of "Permanent" removal services
You’ll see websites claiming they can permanently remove remote management iPhone locks for $50 or $100. Be extremely careful here. Some of these services have "insiders" at big companies who manually delist serial numbers. It’s sketchy. It’s often against company policy. And half the time, these websites are just scams designed to take your money and ghost you.
If a service asks for your IMEI and promises "100% permanent removal" without needing access to the device, they are likely using an exploit in the Apple Business Manager system. It works until Apple patches the hole or the IT admin notices their inventory is shrinking.
Nuance: Is it stolen?
We have to talk about the elephant in the room. If an iPhone has an MDM lock, there's a non-zero chance it was "lost" from a corporate shipment. However, it's just as likely that a company refreshed their tech, sold the old phones in bulk to a recycler, and the recycler didn't verify that the MDM profiles were cleared. This happens constantly. Even big-name refurbished sellers occasionally slip up and send out a locked unit.

If you find yourself with one of these, and the seller won't refund you, you're essentially performing digital surgery to get what you paid for.
Actionable steps to clear the lock
If you are staring at that Remote Management screen right now, here is exactly what you should do, in order of what is most likely to actually work without costing you a fortune.
- The Paperwork Play: If you have a legitimate invoice, find the company name on the MDM screen. Call their IT department. Ask for the "Global Service Desk." Be polite. Tell them you bought a surplus device and give them the serial number. You’d be surprised how often an admin will just click "Release" because they don't want the liability of an old device being on their network anyway.
- The "iMazing" Backup Trick: This is the best DIY method for those who can't get official help. You use the software to "Exit Setup" or restore a clean backup that bypasses the Setup Assistant triggers.
- Command Line (For the Tech-Savvy): There are scripts on GitHub (like those involving
cfgutilon macOS) that can sometimes skip the enrollment profile if the device is in a specific state. This requires the Apple Configurator tool. - The Refund: Honestly? If you bought it on a platform with buyer protection (eBay, Swappa, Back Market), just return it. An MDM-locked phone is technically "Not as Described." It’s a lot less stress to just get your money back and buy a phone that isn't tethered to a random corporation's server.
Avoid the "DNS Bypass" methods you see on YouTube. They are mostly useless for modern iOS versions and only let you use a limited web browser through the Wi-Fi settings. It doesn't give you full access to the phone's features. Focus on either the official release or a local bypass via a PC/Mac. Once you get past that screen, avoid "Erase All Content and Settings" unless you want to repeat the whole process. Always do a "Reset All Settings" instead if you're trying to fix a bug, as that usually leaves the bypass intact.
Check the serial number on a free "MDM Check" tool online before you spend hours on it. Some tools will tell you if the device is "Dep Enrolled." If it says "No," then you might just be dealing with a simple configuration profile that you can delete in the settings menu without any special software.
