Unlock iPhones – O2, Vodafone, Three UK & EE – Orange + T-Mobile

A guide to unlocking iPhones

Why unlock your iPhone?

There are a lot of reasons for unlocking iPhones. Maybe a friend or member of the family has upgraded to a new iPhone 6s and passed you their old iPhone 5c. Maybe you have bought one second hand or maybe you just want to change phone networks.

Another big reason is that it is possible to switch to a cheaper SIM-only tariff which can save you a lot of money (around £300 per year) compared to a standard iPhone contract.

In this guide, we outline how to unlock an iPhone from the UK's major networks, and an alternative official method of unlocking iPhones if that isn't an option or if your iPhone is from a non-UK network.

When you first get your iPhone it will typically be 'locked' to a mobile network, such as Vodafone or O2. This means it'll only work with SIM cards from that network (e.g. an iPhone locked to O2 will only accept O2 SIM cards).

Generally when you want to unlock any other type of phone, you take it to a local phone shop and they unlock it for you. But iPhones are different. The status of the lock is stored on Apple's computers, so even if you pay a shop to unlock an iPhone, it's only ever a temporary solution. At some stage, normally when you connect your iPhone to iTunes for an update or when a new iOS is released, Apple will lock the iPhone again to the network that it was originally on.

So the only way to unlock iPhone is to have the telephone network contact Apple and inform them that the phone is now unlocked. The good news is that generally this is a pain-free, and cheap process.

Stop Press:

It has now become even more pain-free because Official iPhone Unlock.co.uk allows you to bypass the phone network and get your iPhone unlocked within 24 – 48 hours. And it's now even cheaper, with some networks available for under £25. This is great news if you are on EE, T-Mobile or even Vodafone. We have had feedback from customers saying that sometimes dealing directly with those networks can be "awful", with unlocks taking more than 30 days to happen. With Official iPhone Unlock.co.uk you can factory unlock iPhones from these networks very quickly.

Most iPhones are sold locked to a phone network, you'll need to unlock it first before using it on a different network. In this article, we discuss the iPhone unlocking procedures for all of the UK's major networks. You'll need to follow them before you can swap to a SIM-only tariff or using a different SIM card when abroad. If you bought your iPhone directly from Apple, it will normally already be unlocked and you don't need to do this. Please also note that this information is for iPhones that are locked to UK based networks only. All prices should be confirmed before you proceed. This information is provided for advice only.

You really should read all this information, but I know some of you just want the juicy bits, so

Switch and save.

So, you have an iPhone 5s, which you like, but you're due an upgrade. You don't really need one, but it's free right? Well, you can save about £300 per year by switching to a SIM-only contract and keeping your existing iPhone. For example, switch to Three's iPhone SIM deals which comes with 600 minutes, 5000 texts & 1GB internet per month. Assuming that you're currently paying around £35/month on your standard iPhone tariff, Three's deal would save you a massive £301 per year. The 1GB inclusive download allowance is also twice as much as offered on most standard iPhone tariffs (500MB). Although with the new higher speed 4G internet that is available on iPhones 5s and 6, even 1GB of data may not be enough. We don't recommend any particular phone company though so have a look about, you might be able to find something more suitable. But remember to pick the right version of the SIM for your type of phone:

Going on holiday? It's always cheaper to use a SIM card from the local country while travelling abroad. When using your UK SIM card internationally (roaming), you could sometimes be paying too much for phone calls, especially if you're calling someone else who is on holiday with you. Text messages are expensive, and if you ever try to use the internet on your iPhone abroad, be ready for a huge bill. Costs do tend to be lower within the EU but data usage is still too expensive. There are several ways to cut your roaming bill but the cheapest option is to get a local SIM card in the country you're in. This will allow you to use all of your iPhone, including internet access, e-mail and instant messaging without having to worry about your roaming bill. Plan ahead though, because you'll need to unlock the iPhone first to use a different SIM card when abroad, sometimes even if the phone company is the same, e.g. Vodafone here in the UK or abroad.

If you do want to upgrade your iPhone, why not pass on your current iPhone to a family member or even sell it on. An iPhone that can accept SIM cards from any phone network is going to be worth more money than one that is locked to a particular network.

Is unlocking an iPhone illegal?

It is perfectly legal to unlock iPhones in the UK. Individual countries within the EU have their own laws regarding SIM locks but EU law was used to overturn a law in Belgium which made it more difficult to unlock phones. So the good news is that the right to unlock your iPhone is double protected, both in the National Parliament and the European one.

Why are iPhones locked?

Mobile phone companies lock phones to their network because they have spread the cost of the phone over the length of the contract. In my opinion, it shouldn't really matter what you do with the phone as long as you continue to pay your contact, but they claim that they are ‘subsidising' the price of the phone and they don't want you to take their subsidised phone and to use it immediately on a different network.

After you have owned your iPhone for a certain period of time (sometimes as little as 30 days), you can ask your network to unlock it. All UK mobile networks will normally unlock it, although some charge a small unlocking fee. If you want your iPhone unlocked without having to wait then visit Official iPhone Unlock.co.uk, who can unlock iPhones from any network.

In this article, I only talk about the official ways to unlock an iPhone permanently. You may find other unofficial methods of unlocking your iPhone on the web, such a "jail-breaking", "Gevey Sims", RSIM, SAM, Ultrasn0w, but the best advice I can give you is that it's not worth it. These methods might offer to unlock your iPhone by offering you a code to type in or software. There's no guarantees that these methods work: a lot of them of them are scams to take your cash and fail to unlock your phone whereas others could render your phone unusable. Some methods will successfully unlock your iPhone by "jail-breaking" but the unlock is only temporary – Apple regularly update the software on the iPhone and fix these loopholes that let them be jail-broken. When you update the software on your phone it will lock it again. At the very least, your warranty could be cancelled if you unlock your iPhone in an unauthorised way. Do some research ensure that you fully understand what you're doing if you choose to unlock your phone another way.

Which iPhones can I unlock?

The methods of unlocking your iPhone that are described on this page should work with any iPhone purchased in the UK. This includes the iPhone 6s, 6s plus, the iPhone 5s, 5c and iPhone 5 as well as the older iPhone 4s and iPhone 4. As these are official unlocking methods, they will work regardless of your model and your current version of iOS.

Is an unlocked iPhone really cheaper?

If your contract has finished then you can usually save around £300 per year by unlocking your iPhone and switching to a SIM-only contract. Just make sure that the SIM-only contract has a data allowance. The “data” allowance is the amount of time that you can spend online using your iPhone.

All the major networks including O2, Orange, T-Mobile (now combined into EE) and Vodafone also offer SIM-only tariffs which are suitable for use within an iPhone. But you can also use SIM cards from GiffGaff and various other companies. Do some research. We have a comparison page for iPhone SIM only deals but you can also find information on price comparison sites too.

The only other thing to watch out for is the size of the SIM card that different iPhones use. iPhone 4 & 4S users will also need to make sure they receive a micro-SIM card rather than a standard sized SIM card. iPhone 5, 5s and 5c use a nano-SIM.

Did you know that when you change network, you can keep your existing phone number? You do this by requesting a PAC Code from your existing network and letting the new network know this. Switching networks is simple and porting your number should take less than 24 hours.

What is the IMEI?

Before you mobile network starts the iPhone unlocking process, they will ask for the IMEInumber of your iPhone. This is a unique serial number. You'll have to know your IMEI so that your network can unlock your iPhone.

There are three methods of getting the IMEI number of your iPhone:

  1. Go to your iPhone dialler keypad and type *#06# (star-hash-zero-six-hash). The IMEI number will appear on your screen.
  2. In the iPhone menu, go to Settings >General >About. The IMEI number should be listed on the screen.
  3. Connect your iPhone to iTunes on a computer. On the information page, click on the phone number. This tells you several pieces of information about the iPhone, one of which is the IMEI number.

It's probably best to write down your IMEI number (it should be 15 digits long) and make sure you provide the correct IMEI number when unlocking your handset.

Unlocking the iPhone 6s, 6s Plus, iPhone 6 & 6 Plus.

At the time of writing, none of the networks are unlocking the iPhone 6s. But if you have one of Apple's newest model of iPhones, and you want to switch network, don't worry. Official iPhone Unlock.co.uk are large enough that they can negotiate a price with the networks so that they can offer permanent unlocking of the iPhone 6s or 6s plus. It may be more expensive than the previous iPhones, e.g. the iPhone 5c, but it is the only option just now. For example, O2 say that they don't have any plans to offer iPhone 6s unlocking any time soon.

Unlock an iPhone locked to O2

O2 UK logo

Unlocking an O2 iPhone is very easy. The easiest and quickest method is to visit Official iPhone Unlock.co.uk, because you won't need to remember your original account password etc or jump through any of the other hoops that O2 make people go through. In the majority of cases they can unlock your iPhone the very same day (Monday – Friday I think), and they can unlock iPhones 6 and 6s which is something that can't normally be done directly from O2.

If you did buy your iPhone from O2 and you are a Pay Monthly customer then you can ask O2 to unlock your iPhone at any time, as long as it not an iPhone 6 or 6s (including the plus models) (They say that they have no plans to offer unlocks for the iPhone 6 or 6 plus any time soon.) You will have to fulfil the minimum term of your contract (so you can't cancel your contract early just because they have unlocked your iPhone). But don't wait until your contract is over if you plan to use O2 to unlock the iPhone. In cases where the iPhone is out of contract, even if you have paid 24 months to them, they class it as an "Non-O2" iPhone and will expect you to pay for at least 30 days of Pay-As-You-Go SIM use before they'll begin the process.

If you have a standard O2 Pay-As-You-Go SIM card, where you need to buy top-ups, then you will need to wait 12 months before O2 will unlock your iPhone.

If you need it done faster or if you bought the iPhone from someone else and you're not the original O2 customer, then you won't normally be able to get O2 to do the unlocking. But that doesn't mean you can't get your iPhone unlocked. Visit Official iPhone Unlock.co.uk and they should be able to unlock your iPhone in a day or so.

It takes up to 3 days to unlock an iPhone from O2 or if you want it done the same day, use Official iPhone Unlock.co.uk.

Unlock an iPhone from EE, Orange or T-Mobile.

EE UK logo

Unfortunately EE seem to be very strict on unlocking iPhones. If you have purchased an iPhone or been given an iPhone which is locked to EE then it will be a lot easier for the original owner to ask for it to be unlocked. If this is not possible then EE may ask you to enter into an SIM contract for 6 months before they will unlock the iPhone. If you don't want to spend 6 months waiting and also the cost of a 6 month contract then you should look at Official iPhone Unlock.co.uk.They can unlock your EE iPhone in a matter of hours. The upfront cost is higher, but compared to a 6-month contract and the delay it may work out to be cheaper.

If you can get EE to unlock your iPhone then there is usually a fee that is either paid with your next bill or comes out of your phone credit. So make sure you have enough credit if you are on Pay As You Go. On a monthly contract you'll need to call 150 from your EE iPhone, or 07973 100 150 from another phone.

With a pay as you go phone, call 450 from your EE iPhone, or 07973 100 450 from another phone.

Unlock an iPhone from Vodafone

If you bought your iPhone direct from Vodafone and the contract has not ended then Vodafone will normally unlock your iPhone for you. It takes about 2 weeks and they charge a fee of £19.99 on Pay Monthly or Pay As You Go. If you are on Pay As You go, make sure that you have at least £20 worth of credit on your iPhone before you ask them for an unlock, as they take the fee from your credit.

If you are not the original owner of the iPhone, for example if you bought it from eBay or privately from someone else, then you may not be able to get Vodafone to do the unlock for you. Official iPhone Unlock.co.uk offer iPhone unlocks for Vodafone that are completed in 2-3 days, even if you were not the original owner. So If you want it done faster, or if you are not the original owner go directly to Official iPhone Unlock.co.uk.

Unlock an iPhone locked to Three

Three UK logo

iPhones that are locked to Three are one of the easiest to get unlocked. If it’s a new model then it may have been shipped unlocked, so try another SIM card in there and see if it works. If it’s older, which is the most likely because generally people unlock their iPhones at the end of a 2-year contract so that they can pass them on, then you may need to get it unlocked first. On weekdays (Monday – Friday), Official iPhone Unlock.co.uk say that they can unlock an iPhone locked to Three in a matter of hours. When you compare that to how long a network like EE takes, it’s excellent.

When using Official iPhoneUnlock.co.uk, there is no restrictions on time – so you don’t need to have had your contract for any amount of period or use a Three Pay-As-You-Go SIM for 30 days. Just click on Official iPhoneUnlock.co.uk and follow the instructions for Three.

Unlock an iPhone locked to Tesco

Tesco Mobile logo

Official iPhoneUnlock.co.uk are now able to unlock Tesco Mobile iPhones, and are quoting a turn around time of around 1-2 days. This is perfect for someone who has bought their iPhone from eBay or got it from a friend. But if you are an existing Tesco Mobile customer, then it may be cheaper to go directly to Tesco, especially if you have had your iPhone for more than 1 year. This is what Tesco Mobile’s website says, “It normally takes 7 working days for your unlocking code to come through, but occasionally it can take up to 28 days, depending on your device. Call us on 0345 300 6660.”

I've unlocked my iPhone. What's next?

Once you've informed your mobile network that you want to unlock your iPhone and you've made the necessary payments, your mobile network needs to inform Apple. Apple maintains a central list of unlocked iPhone devices and it can take up to 14 days for your iPhone to be added to this list. Once your device is on the list, you'll need to connect it to iTunes to complete the unlocking process. A message should pop-up in iTunes to let you know that your device has been unlocked.

iTunes will finish off the iPhone unlocking process.

How can I check to see whether my iPhone has been unlocked?

The easiest way to test whether your iPhone has been successfully unlocked is to insert a SIM card from a different network. All of the UK's major mobile networks offer free Pay As You Go SIM cards.

If you've unlocked your iPhone through the methods discussed on this page, you will see a message that says, "Congratulations, your iPhone has been unlocked", in iTunes once your unlocking request has been processed.

What about stores which offer to unlock iPhones?

Some newsagents and phone shops may offer to unlock iPhones. They will usually do this by "jailbreaking" your device. This is not the recommended method of unlocking as it isn't a permanent unlock: you'll need to jailbreak the phone each time that Apple releases a new software update. It may also invalidate your warranty.

The only official ways to unlock iPhones is either through your mobile network operator using the methods listed on this page, or by using Official iPhone Unlock.co.uk. We strongly recommend paying the small fee to unlock your iPhone officially and legitimately because it's the only way to be sure that your unlock will be permanent.
