If you’ve purchased a SIM-free iPhone from certain UK retailers, it may have locked itself to the first mobile network you used on the handset.
Typically, a SIM-free mobile phone is also an unlocked smartphone. As you’ll have paid the full retail price for your handset upfront (up to £1,000 for the latest flagship smartphone), you’ll normally be able to use the handset on the mobile network of your choice. For instance, you could get a cheap SIM-only deal or you could use a free Pay As You Go SIM card inside the handset.
Historically, things haven’t always been so simple when purchasing a SIM-free iPhone in the UK. In the past, SIM-free iPhones from certain UK retailers (including the Carphone Warehouse) would lock themselves to the first mobile network used on the handset. The iPhones were also restricted to only working on UK mobile networks. Nowadays, this is no longer the case for newly-purchased iPhones but you may still be affected if your iPhone was purchased in the past.
We’d currently recommend buying your SIM-free iPhone from John Lewis. You’ll benefit from a 2-year guarantee at no extra charge, along with the John Lewis “Never Knowingly Undersold” promise. The standard warranty on an iPhone is just 1 year when purchased from most other retailers.
In this article, we’ll discuss SIM-free iPhones in the UK and we’ll look at how the unlocking status differs depending on where you buy it. We’ll also look at the best places to buy a permanently-unlocked iPhone and how you can unlock a SIM-free iPhone from your mobile network.
iPhone: Unlocking Status By Retailer
In the UK, you can now buy a permanently unlocked iPhone either directly from Apple or from a range of third-party retailers (including John Lewis, Argos and the Carphone Warehouse). You’ll get a SIM-free iPhone that’s permanently unlocked for use on any network (there is no longer the automatic locking behaviour that affected some iPhones in the past).
You can also buy a permanently unlocked iPhone from three UK mobile networks: BT Mobile, giffgaff and Three. Both giffgaff and Three offer the iPhone on Pay As You Go with a minimum top-up of £10. Meanwhile, BT Mobile only offers the iPhone on a Pay Monthly basis with a 24-month contract.
The following table summarises the unlocking status of iPhones purchased from various UK retailers:
|Retailer||Will the iPhone be permanently unlocked?|
|Direct||Apple Store||✔ Yes, the iPhone will be permanently unlocked.|
|Third-Party Retailers||Argos||✔ Yes, the iPhone will be permanently unlocked.|
|Carphone Warehouse||✔ Yes, the iPhone will be permanently unlocked (since July 2017).|
|Currys||✔ Yes, the iPhone will be permanently unlocked (since July 2017).|
|John Lewis||✔ Yes, the iPhone will be permanently unlocked.|
|PC World||✔ Yes, the iPhone will be permanently unlocked (since July 2017).|
|Unshackled||✔ Yes, the iPhone will be permanently unlocked.|
|Mobile Network||BT Mobile||✔ Yes, the iPhone will be permanently unlocked.|
|giffgaff||✔ Yes, the iPhone will be permanently unlocked.|
|Three||✔ Yes, the iPhone will be permanently unlocked.|
|EE||✘ No, the iPhone will be locked to EE.|
|O2||✘ No, the iPhone will be locked to O2.|
|iD Mobile||✘ No, the iPhone will be locked to iD Mobile.|
|Tesco Mobile||✘ No, the iPhone will be locked to Tesco Mobile.|
|Virgin Mobile||✘ No, the iPhone will be locked to Virgin Mobile.|
|Vodafone||✘ No, the iPhone will be locked to Vodafone.|
If your iPhone was originally purchased from the Carphone Warehouse, Currys or PC World before July 2017, it will lock itself to the first mobile network used on the handset. This was previously summarised in the small print available on the Carphone Warehouse website (this has since been removed as it no longer applies to new sales):
The iPhone will lock itself to the network of the first SIM card that is used in the phone. Subsequently attempting to use it on any other network, for example by replacing the SIM card, may mean it becomes permanently unusable. SIM free iPhones can only be used with a UK-network SIM card, and will not accept foreign SIM cards.
To be clear, it’s been confirmed by Carphone Warehouse (e.g. on Facebook, Twitter and their official website) that this policy no longer applies for SIM-free iPhones purchased from July 2017 onwards.
Buying An Unlocked iPhone
In the UK, there are now numerous retailers where you can buy a permanently-unlocked iPhone.
The following table compares how much you’d pay for a permanently-unlocked iPhone at various retailers:
|Retailer||iPhone XS||iPhone XS Max||iPhone XR||iPhone X||iPhone 8|
|John Lewis & Partners||£999.00||£1,099.00||£749.00||£749.00||£599.00|
|Currys PC World||£999.00||£1,099.00||£749.00||£799.00||£599.00|
We often recommend buying a SIM-free iPhone from John Lewis as you can benefit from their 2-year guarantee and their “never knowingly undersold” promise. You’ll also get a 2-year guarantee included in the price (the standard warranty is just 1 year when purchased from most other retailers).

If you opt to buy an unlocked iPhone from giffgaff or Three, you’ll need to top-up at least £10 on your giffgaff or Three Pay As You Go SIM card. There’s no obligation to continue using your SIM card as you can switch to another network at any time without the need to unlock your iPhone.
Unlocking a SIM-Free iPhone
If you have a SIM-free iPhone that was originally purchased before July 2017, it may have locked itself to the first mobile network you used on the handset. To use it with a SIM card from a different mobile network, you’ll need to go through the process of unlocking it.
The first step is finding out which mobile network the iPhone has locked to. For most people, this should be fairly straightforward as it’s the first mobile network you used on the device (either EE, O2, Three or Vodafone). If you were using a virtual network operator such as giffgaff or Tesco Mobile, your iPhone may have locked itself to the underlying coverage provider.
If you aren’t sure which mobile network your iPhone has locked to, you can find out by calling AppleCare or by visiting your nearest Apple Store and making a Genius Bar appointment. The staff at Apple will check the ‘activation policy’ of your iPhone. This will tell them which mobile network your iPhone is currently locked to.
Once you’ve found out which mobile network your iPhone has locked to, follow the relevant instructions for unlocking it from that network:
If your SIM-free iPhone has locked itself to the EE network, you can unlock it by contacting EE. It’s free to unlock the iPhone if you’re an EE Pay As You Go customer – you can order a free EE SIM card to join the network. Alternatively, if you’re a non-customer, it will cost £8.99 to unlock your iPhone. You can reach the EE unlocking team on 0800 956 6000 (select option 2 and then option 4).
If your SIM-free iPhone has locked itself to O2, you can unlock it once you’ve been an O2 Pay As You Go customer for at least 12 months. There’s a fee of £15 to unlock your iPhone on O2 Pay As You Go. Alternatively, customers with an O2 Pay Monthly contract can unlock their iPhone for free at any time.
If your SIM-free iPhone has locked itself to Three, you can unlock it for free at any time as a Three Pay As You Go customer. Simply order a free Pay As You Go SIM card from Three and then fill out the unlocking form on Three’s website.
If your SIM-free iPhone has locked itself to Vodafone, you can unlock it for free as a Vodafone Pay As You Go customer. You can join by ordering a free Vodafone SIM card, which must be used for at least 30 days before you request the unlock. Alternatively, you can use your Pay Monthly contract for unlocking as long as you’ve had it for at least 3 months.
Once you’ve unlocked a SIM-free iPhone, it will be permanently unlocked for use on any network. It should also start working on mobile networks outside of the UK.
Other Brands Of Mobile Phone
The automatic locking of SIM-free devices has only occurred on Apple iPhone devices. If you’re using a SIM-free smartphone from any other manufacturer (e.g. from Samsung, Huawei, Google, Sony, Motorola, etc), it will not lock itself to the first mobile network used.

If av baught a phone off someone and they got or on monthly payments and it doesn’t come with a sun but they aren’t going to pay the bill for the handset will virgin block it ??
If the phones after July 2017 does not get locked to the first carrier network as in the past, does that mean people can’t do fraud when selling you a second hand phone say the iPhone 11 if factory unlocked? Example, selling you a phone and reporting it stolen via imei number and getting it blocked. I wouldn’t think there would be anything to be cautious about right as if the phone doesn’t get locked to any carrier no carrier would want to block the imei number as it’s nothing to do with them.
I know to be on the safe side buying phones with no sim being put in that is factory locked Is a safe method.
Be interested to hear your thoughts.
Thanks for your comment. I don’t think it makes a major difference here. When a phone is reported as stolen, it will normally be IMEI-blacklisted across all of the UK networks. Therefore, whether you’re buying a phone that’s locked or unlocked shouldn’t make any difference 🙂
Hope this helps,
I just bought iphone 11 with Vodafone contract accidently i put my Libera sim first and then Vodafone. Vodafone doesn’t shows any network coverage. Does it affect the contract?
Thanks for your comment. I don’t believe the iPhone 11 locks itself to a network (and this is especially the case with iPhones provided on a contract, which have never locked to the first network used).
