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

An IMEI is a 15-digit number that connects your iPhone with the SIM card inside it. It’s unique to your device and it can’t be moved over to another mobile phone.

Your IMEI’s stored in a database called the Equipment Identity Register (EIR). This is used by mobile providers and manufacturers to store and track information about your phone. Your locking status is one of those pieces of information.

Finding your IMEI is easy. Just type *#06# into your iPhone screen using your cell phone keypad. Or find it in the ‘Settings’ menu. You’ll also see it on your SIM card or under the battery.

How to network unlock iPhone 3GS.

Unlocking iPhone 3 and other iPhone models

The network lock on your iPhone 3G or iPhone 3GS is a software code that exists behind-the-scenes. It's there to stop your phone connecting to alternative mobile networks.

It's also known as a SIM lock, network, or (master) subsidy lock. And, crucially, it isn’t a lock you can see or remove manually by typing something into your phone or changing a setting. Learn more about how to unlock iPhone network for any Apple device.

If your phone is locked try to insert a SIM card from another provider, you won't get a signal. And will get an error message, such as: 'Non accepted sim card', 'Incorrect simcard inserted', and 'Network blocked.'

Putting a network lock on a phone means networks are able to control customers by making it harder for them to move to a different network. Unless, of course, they buy a new phone.

The most effective and unobtrusive way on how to unlock your iPhone 3GS is to use technology designed to do just that.

Mobile Unlocked’s specialist software makes the unlocking process seamless from start to finish.

It's simple to use because all it requires from you is the IMEI number of your phone. It's convenient because everything's done online and you can keep using your phone throughout. It's safe because your phone stays with you the whole time. And it's quick because there's no complicated admin or security questions to contend with.

You won’t need a pin code, unlock code or unlocking sequence because the unlock takes place automatically “over-the-air” through the Apple servers. Our software has authorised whitelisted access to the manufacturer database, which it uses to perform the unlock.

And there's no factory unlock or loss of data at all.

All you need to do, once your phone is remotely unlocked and permanently unlocked (and network free!) 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-supported networks, so it will work whether you need to insert a EE sim card or a O2 or Tesco Mobile.

See our full guide if you’re looking to unlock an O2 phone.

If you don’t know the network you’re on, it’s easy to find out. Just use our iPhone 3GS network check.

Note: It won't work on a device that has blacklist status, so if you're unsure, run a blacklist check first.

Can you also unlock other versions of the iPhone 3 and other iPhone models?

The iPhone 3G and iPhone 3GS are both compatible with our unlocking software. The following Apple devices and iPhone models are supported too:

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.

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.

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.

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.

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.
