Is your iPhone locked to a specific network or carrier? Check out our guide to unlocking your iPhone so you can use any SIM card in it.
How to unlock your iPhone? Contact your provider and request an unlock using the contact details and online tools listed below.
- If you’ve not got the original SIM, you’ll need to reset the phone before it can be unlocked.
- Power down the phone, then replace the old SIM card with a SIM from a different network.
- Check that the iPhone is able to connect a phone call over the new network.
That’s the shortened version, but let’s go through those steps in a bit more detail.
Contact your network provider
We’ve separated the article by the UK’s most popular carriers to talk you through how to go about getting your iPhone unlocked if it’s restricted to that network. Scroll down to your carrier to find out their specific process for unlocking a device.
EE (including Orange and T-Mobile)
If you’ve had your EE, Orange, or T-Mobile account for at least six months and have paid all of your bills to date, EE will unlock your iPhone for you. It’ll cost you £8.99 if you’re still within the contract, though, and it could take up to seven days, which is not ideal.
If you’re a Pay as You Go customer and have enough credit to pay the £8.99 admin fee, EE will unlock your iPhone for you at that price.
However, if you’re not an EE customer and you’ve got an iPhone that’s locked to EE, you’re going to need to do some digging and if you got it from eBay the chances are it’s not going to be easy. You’ll need to find out the original owner’s name, EE phone number, and maybe some additional account information.
Of course, it’s not always going to be possible to find out the information you need, in which case you might need to use a third-party unlocking service as described later in this article.
Similarly, Vodafone requires you to have an account or know the details of the person who did. If those details are already available, you can go straight ahead and use Vodafone’s online unlocking form.
It’ll take up to 48 hours for the company to get back to you and up to 10 days to unlock it, and it’s free to do so.
Three makes things much simpler, you’ll be pleased to hear. On its website, the carrier states that any iPhone purchased after 1 January 2014 from Three is automatically unlocked as soon as you connect it to WiFi or connect it to iTunes.
But even if you purchased your iPhone before that, you simply need to connect the iPhone to iTunes and restore the device to unlock it. You’ll want to back up your content first, though, as restoring it is going to wipe all of its data.
Alternatively, you can fill out Three’s online form.
If your iPhone is locked to O2, you’ll have to fill in an online form to unlock it. If you’re a Pay Monthly customer you can unlock your phone at any time, but you’ll still be required to finish paying for the rest of your contract.
Pay & Go O2 customers are required to wait for 12 months before they can unlock their iPhone. That’s according to O2’s website, which also claims that it’ll cost £15, but when we spoke to an O2 representative they said they could unlock all O2 iPhones for free.
The same representative also told us that, if you’re not an O2 customer, you can simply put a non-O2 SIM card into the iPhone, plug it in to your computer and then open iTunes to unlock the iPhone, but we haven’t tested whether this works.
We would recommend trying this before filling out O2’s online form, even if you are an O2 customer, as it could save you a lot of time. (It takes up to 72 hours for O2 to unlock it for you.)
Virgin says any iPhone purchased from the company within the past year or so will be unlocked already, but some older iPhones might not have the same luck.
The good news is that all you’ll need to do is update your iPhone to iOS 8 or later and it’ll be unlocked for you. (Note that updating iOS will install the most recent version that your device is capable of running, so at time of writing most active iPhones will get iOS 10. This is fine for these purposes, and has lots of nice new features too.)
If your iPhone isn’t compatible with a sufficiently recent version of iOS – that is, if it’s an iPhone 4 or older – you’ll be able to perform a full restore of your iPhone to unlock it. Don’t forget to back up your data first, though.
If you’ve been with Tesco Mobile for 12 months or more, or if you’ve completed your contract, you’ll be able to get an unlock code from Tesco for free by calling 0345 301 4455 and choosing “unlock your mobile”.
Giffgaff has a handy tool that helps you figure out how to unlock your Apple iPhone from its network, which you’ll find here.
Using a third-party unlocking service
An alternative to contacting your carrier and asking them to unlock the iPhone is to use a mobile phone unlocking service. There are many retailers in most areas who will arrange an unlock code for a small fee (usually around £25).
Although they aren’t always reputable, you can also find online services that will unlock your iPhone, but we would advise against it. If you do decide to use one, please make sure that you read all of the small print before you buy, because they can surprise you with extra bills at the end of the process.
How much should I pay?
Ideally you shouldn’t pay anything to unlock your iPhone, because your carrier should unlock it for you for free. But some carriers are still setting admin charges of up to £20. Third-party companies seem to charge between £10 and £25, and we wouldn’t pay more than that. Shop around if anybody quotes you a higher price than that.
How to tell if the unlock worked
Once your phone has been unlocked you will receive a confirmation from the carrier. Now follow these steps:
- Power down the phone: hold down the Sleep/Wake button and swipe your finger across as directed.
- Use the SIM card tool (or a straightened paper clip) to eject the SIM card holder from the side of the phone.
- Remove the old SIM card from the card holder. Place your new SIM – from a different network – into the card holder.
- Reinsert the SIM card holder into the iPhone.
- Make a phone call, and check that the iPhone is able to connect over the new network. If so, it’s unlocked!
How to update an unlocked phone without the SIM card
If you’ve requested an unlock from your carrier, but have not got the original SIM card, you will need to reset the phone before it will be unlocked. First, ensure you have requested an unlock from the carrier. Now follow these steps:
- Back up your iPhone. Either using Backup (Settings > iCloud > Storage & Backup > Back Up Now) or by connecting the iPhone to a computer and Using iTunes to perform a backup.
- Erase your iPhone. Click on Settings > General > Reset > Erase All Content and Settings.
- Complete the setup assistant and restore from your backup.
The phone should now be unlocked.
When you turn the iPhone back on, complete the setup assistant and restore it from the backup you created. Then you can insert the new SIM card and it should now work.
