Why you should unlock your iPhone 4

The cell phone industry’s bigger than ever, with new deals appearing all the time. But if the sim card in your device is locked to one network, you won’t be able to explore them. An unlocked phone, however, is full of opportunities.

What's an IMEI, and where can I find it?

An IMEI is a 15-digit number that links your phone with the SIM card inside the device. Your IMEI’s a bit like your fingerprint or DNA. It’s unique to your device and it can’t be transferred to another phone.

Your IMEI’s stored centrally in a database used by the operating systems of mobile providers and manufacturers. An IMEI is integral to a phone unlock because it holds information about your phone, including whether or not it’s got a carrier lock in place.

It’s easy to find your IMEI. Just type *#06# into your iPhone screen using your cell phone keypad. Or find it in the ‘Settings’ menu.

How to carrier unlock iPhone 4 and 4S.

Unlocking iPhone 4 and other iPhone models

The carrier lock on your iPhone 4 doesn’t have a physical presence on your device. Rather, it’s a software code that exists behind-the-scenes. And its purpose is to direct your phone to connect only to a specific network. For further details see our unlock iPhone device guide.

But most importantly, for you, a network lock or SIM lock, carrier lock or (master) subsidy lock, isn’t a lock you can see or remove manually. That requires specialist software with authorized access to the manufacturer’s database.

Born of technology, the answer to your iPhone 4 carrier lock lies with technology. More specifically, a network like Mobile Unlocked’s phone unlock tool that has the software and the right whitelisted access required to remove the unlock status from the central database.

Mobile Unlocked’s specialist software streamlines and simplifies the unlocking process. Using just the IMEI number of your device it remotely unlocks your phone in just a few hours. No tricky forms to fill in.

With the iPhone 4, you won’t need an unlock code. Rather, the unlock takes place automatically “over-the-air” hooking up directly with the Apple servers.

All you need to do, once done, is swap your old SIM card for your new provider’s SIM card.

And the good news is, it doesn’t matter what network you’re on. Our network unlock tool is compatible with phones registered on both GSM and CDMA networks, including Mobilicity, Virgin Canda and Koodo.

If you don’t know the network you’re on, it’s easy to find out. Just use our iPhone 4 carrier check.

Can you also unlock other versions of the iPhone 4 and other iPhone models?

Both the iPhone 4 and iPhone 4S are compatible with our unlocking software, which also supports the following Apple devices and iPhone models:

iPhone 14, iPhone 14 Plus , iPhone 14 Pro, iPhone 14 Pro Max, iPhone 13, iPhone 13 Pro, iPhone 13 Pro Max, iPhone 12, iPhone 12 mini, iPhone 12 Pro, iPhone 12 Pro Max, iPhone 11, iPhone 11 Pro, iPhone 11 Pro Max, iPhone Xr, iPhone XS, iPhone XS Max, iPhone X, iPhone 8, iPhone 8 Plus, iPhone 7, iPhone 7 Plus, iPhone 6, iPhone 6 Plus, iPhone 6s, iPhone 6s Plus, iPhone SE, iPhone 5, iPhone 5C, iPhone 5S, iPhone 4, iPhone 4S, and iPads.

Further types of iPhone unlocking

Looking for solutions to other phone locking issues like how to unlock lock screen? Here’s a rundown of the most common problems and ways to solve them. Here’s a rundown of the most common problems and ways to solve them.

We recently launched a new service for all type of Apple phone unlocks: iPhone is disabled how to unlock it.

How to unlock an iPhone 4 that’s been disabled

If you’re locked out of your phone because you don't know the screen passcode or pin code, your life’s pretty much on hold. So you’ll want a solution fast. There are a few ways of tackling this. But most of them involve a factory reset, which will cost you all of the data, settings and passwords stored on your disabled device. They’re also more clunky in terms of process. So if you want to keep hold of all your precious, personal data, and if speed and certainty are of the essence, the best option is, again, to look for a smart tech solution.

Here’s where Mobile Unlocked can help. Our screen unlock tool can get you back into your disabled iPhone 4 in a matter of seconds.

Plus, it works for other phone locking scenarios too, including Apple ID login issues, MDM lock problems and Screen Time password lockouts.

Let’s look at the process:

Step 1.

Go to how to unlock disabled iPhone 4 without passcode unlocking tool.

Step 2.

Select unlocking mode: Screen lock.

Other options include: Apple ID, MDM, Screen Time passcode.

Step 3.

Connect device.

Use a USB cable to connect your phone to a PC or laptop.

Step 4.

Click ‘Remove lock’.

Your unlock will take place immediately and be complete in seconds.

Two ways to unlock iPhone 4 without passcode using iTunes

You’ve probably come across Apple iTunes before. But did you know you can use it to get past the locked screen of your disabled iPhone 4? It basically works by restoring the device to its factory settings. And it’s pretty effective. But take note - it may wipe everything off your phone. You’ll be able to get into your phone. But you’ll be starting from scratch and have to set it all up again.If you’re prepared for this, here are two methods you can use, depending on whether or not your phone has previously synced to iTunes on the computer you’re using.

How to unlock iPhone 4 on a trusted computer

If you synced your phone to your computer before it was disabled or locked out, this is the method to use. Here’s how it works

Step 1.

Connect your iPhone 4 to the computer with the latest version of iTunes installed.

Step 2.

Open up iTunes on the computer.

Step 3.

As soon as iTunes has located your device click on it.

Step 4.

Choose ‘Summary’, followed by ‘Restore iPhone’.

How to unlock iPhone 4 in recovery mode or DFU

If this is the first time you’ve connected your disabled iPhone 4 to iTunes on the computer you’re using, you’ll need to put it into recovery or DFU mode before activating the factory reset. DFU stands for Device Firmware Update. It’s an extreme firmware package reset, which reloads the software and the firmware of your device. The process looks like this:

  • Press and hold both the ‘home’ and the’ top’ (or’ side’) buttons at the same time. Keep holding them until you see the recovery mode screen. While pressing and holding the Home button, reconnect the USB cable to the device. The device should turn on.

NOTE: This method also works for an iPhone 6 and 5. But if you’re trying to unlock an iPhone 7 you need to press and hold the top (or side) and volume down buttons at the same time.

  • Locate your device on your computer using iTunes. When you have identified it, you will see the option to Restore or Update.
  • Click the 'Restore iPhone' button
  • Click ‘Restore’ and ‘Agree’

What to look out for

If you haven't synced your iPhone with iTunes before there’s a chance iTunes may not recognize your device. In which case, the process may not work. If this is the case, you can use Siri or the ‘Find My’ app on iCloud

How to unlock iPhone 4 using iCloud

A type of remote manager for your iPhone, iCloud’s ‘Find My’ app can also erase all of the data on your device - including your passcode. This feature is designed to protect your data should your phone be lost or stolen. But it’s also useful if you’ve forgotten your passcode. This method also requires a factory reset. So be prepared to backup or lose all the data, settings, photos, messages and other passwords and logins on your device.

  • Open a browser on an iOS device with ‘Find My’ installed
  • Log in with your iCloud account, Apple ID password
  • Click ‘All Devices’
  • Select your locked iPhone 4 from the map
  • Click ‘Erase iPhone’

What to look out for

  • Your device must be connected to wifi or the internet
  • ‘Find My’ needs to have been activated on your device before the phone was disabled

How to unlock iPhone 4 using Siri

Bugs are usually a pain. But there’s a bug running on Apple’s iOS versions 8.0 through to iOS 13 that might actually give you pleasure.

If you’re “lucky” enough to still be running on any of those versions, you can exploit that bug to unlock your phone. How? Using super helpful Siri! With Siri you can get back into your locked phone without a passcode, Apple ID or computer. The good news is it doesn’t require a factory reset so it won’t erase your data. But the not-so good news is, it isn’t 100% reliable and the steps (13! Count them!) involved are rather complex. That said, it’s worth a go if you’ve got the time and meet the rather random criteria.

  • Activate Siri by holding your ‘Home’ button down.
  • Ask Siri: 'What's the time now?' (Siri will display the local time.)
  • Click on the clock icon. (You will see a menu of the World Clock with some small icons appear on the right-hand side.)
  • Click on the plus sign in the upper right corner of the screen.
  • Type any characters into the ‘search box’ that appears.
  • 'Select All' these characters. (You’ll be presented with various options such as: cut, copy, define, and share.)
  • Tap ‘Share’
  • You will see a pop-up window. Tap on the Message icon.
  • A ‘New Message’ window will appear, type any character in the 'To' field, and press ‘Return’ on your keyboard.
  • The text will be highlighted in a green color. Once you see this, tap the ‘+’ icon to select ‘Create New Contact’.
  • Tap the ‘Add Photo’ button and select the ‘Add Photo’ option.
  • Go to the photo library and open up any album.
  • Press the ‘Home’ button.

Ta-da! Your passcode should now be removed!

TIP: You can also create a voice command on your iPhone which allows you to use Siri to unlock the iPhone when you forget the password.

Thank you MobileUnlocked! This was a much cheaper alternative to buying a new iPhone Pro Max! It couldn’t have been easier to unlock with MobileUnlocked, all I had to do was provide my imei number (it’s so simple and they clearly show you how to do this) and that was that. Amazing service – 100% would recommend!

Tim Lewis 18/04/2023

Super Quick!

It was such a simple and cost effective process! My iPhone Xs was unlocked within no time and I will be returning to unlock my new Apple Watch 4.

Jeffery Brook 15/10/2023

I thought it would be complicated!

I can’t believe how quickly MobileUnlocked handled my request. Looking online, I read it can take up to 60 days to unlock a device, but MobileUnlocked unlocked my iPhone 14 Pro Max in under 24 hours! Fantastic service which I would highly recommend.

Dang Lee 21/07/2022

iPhone 11 Pro is Unlocked

Alex Darby 08/09/2023

Really Easy Process

So quick and simple! I followed the simple instructions MobileUnlocked provided and within 12 hours of placing my order my phone was unlocked. I would recommend this service to everyone and I will certainly be coming back when I need to unlock my next new phone.

Chad Otis 24/01/2023

Such amazing company!

MobileUnlocked are such a fantastic company! They don’t overcomplicate or overcharge, and their staff were both friendly and informative. My phone was successfully unlocked within hours, saving me both time and money. Highly recommend.

Laura Johnston 07/10/2023


I can’t fault my experience with MobileUnlocked. I followed the clear and simple instructions on their website and my request was carried out the following morning. The service couldn’t have been easier, and the instructions couldn’t have been clearer. My phone is now unlocked and I can’t recommend this company enough.

V Heggie 07/09/2022

Unlocked iPhone 6

Despite my phone being an older model, MobileUnlocked were still able to unlock it. The instructions were clear and simple, and my iPhone 6 was unlocked in no time (making me a huge saving!). Thank you MobileUnlocked! Highly recommend.
