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.



Unlock iPhone 4


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 T Mobile, AT&T, Sprint and Verizon.

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.

Amazing!

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!

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.

iPhone 11 Pro is Unlocked

This was such a quick and simple process, all I had to do was provide my imei number (which they tell you how to do) and I had my unlocked iPhone within 24 hours. Thank you MobileUnlocked!

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.

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.

Flawless

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.

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.
