How to Make a Locked iPhone Accept Any Sim Card
Happy with your iPhone, but think you’re paying over the odds for data and texts? We’ve all be there, to be honest. Sometimes swapping mobile networks is a good idea, but there might be a slight snag: If your iPhone is locked to a particular network, it’ll need to be unlocked before it will accept your new SIM.
It sounds complicated – and it is. Sorry, about that. Anyway, it’ll be fine, because this handy guide contains all the information you need to know.
How to tell if your iPhone is locked
Not sure if your phone is locked? Well, this bit’s pretty easy. Just pop out your existing SIM and try the new one. If you bought your iPhone direct from an Apple Store, it’ll be unlocked by default, so swapping between SIMs from different networks is quick and easy – and you shouldn’t even need to restart your phone.
If however, your iPhone is locked, you’ll get error messages such as “Invalid SIM”, or “No SIM card installed”. This might not mean that your phone is locked – it could just be iOS throwing a fit. If you’re in this bracket, it’s just a simple case of flicking Flight mode on and off and restarting the phone – or just cleaning out some pocket fluff and reseating the SIM card.
Alternatively, go to Settings | General | About and tap “Check for a carrier settings update”.
If you get the “SIM locked” message, though, you’re out of luck and will need to find a way to unlock your phone – and here’s how.
What do I need to unlock my iPhone?
If you got your phone as part of a contract, the first step is to contact your mobile network and obtain a personal unblocking code (PUC).
Most networks will provide this service for free after a certain time period, but if you want to unlock before your contract is up – or if you’re on a pay-as-you-go contract – you’ll probably need to shell out up to £20 for the privilege.
If you bought your phone second-hand, it’s a little trickier: if you can’t get the seller to unlock it for you, you may need to jump through some hoops.
Certain networks, such as EE, allows you to take second-hand phones to a store and get them unlocked, but other options such as using third-party websites or local mobile shops are entirely at your own risk (TOP TIP: the ever-helpful Giffgaff actually rates the unlocking services on their list alongside the mobile providers). If you can do it via a mobile network, then that’s by far your best bet – and it’s often cheaper, too.
How to unlock your iPhone: Giffgaff
Giffgaff sells unlocked iPhones so, if you bought your phone from them, you’re free as a bird. If, however, you’re on Giffgaff and the phone is locked to another provider, they offer an amazingly helpful iPhone “unlockapedia” that tells you how to go about unlocking any iPhone from the original iPhone all the way through to the iPhone 7 – and from any network.
How to unlock your iPhone: Three
If you bought your iPhone from Three after 1 January 2014, it will already be unlocked. If not, you’ll have to fill out a form on the company’s website. After you’ve done this, you’ll be sent an unlock code, along with instruction on how to use it.
How to unlock your iPhone: Vodafone
If you’re a PAYG customer, you’ll need £20 credit on your account because the unlock fee is £19.99. You’ll also need to have been using your PAYG SIM for more than 30 days. If you’re a Pay Monthly customer and you’ve had your phone for more than 12 months, the unlock fee is waived. If not, the £19.99 fee applies, but you still have to have been a customer for three months and have paid all your bills to date. The process takes around 48 hours, and you’ll get an email to inform you once your device is unlocked.
How to unlock your iPhone: EE, Orange, T-Mobile
If you got your iPhone brand-new or through an upgrade on EE, Orange or T-Mobile, you can unlock it for £8.99 regardless of what type of contract you’re on. Pay Monthly customers need to have had their phone for at least six months (and used it actively with that SIM in that time), but PAYG customers can unlock it straight away, as long as it was locked to EE, Orange or T-Mobile in the first place. Anyone who fulfils these criteria can head on over to EE’s website and start the process straight away, but it takes up to ten days for the unlock to take effect.
How to unlock your iPhone: O2
PAYG customers can unlock their iPhone after 12 months – for a £15 fee. Pay Monthly customers can unlock their iPhones any time they wish to, though, and for free. Whichever camp you’re in, you can start the process by heading over to My O2 online or from the main menu of the My O2 app. Once the process is started, it’ll take up to 72 hours to take effect.
How to unlock your iPhone: Tesco Mobile
PAYG customers can unlock their phone for free once they’ve had their phone for 12 months, or pay £10 before the first year is up. Pay Monthly customers get free unlocking, but eligibility partly depends on whether a new version of the phone has recently released. The unlock process takes seven days, and you’ll need to call 0345 300 6660 to request the service because there’s no online alternative.
