If you've been using the same mobile phone for several years and you're looking to change your network, you may have noticed that it needs unlocking first. Many high street shops can help you do this for a fee, but here's a simple guide on how to unlock your mobile phone at home, no matter what network you’re on.
On this page, we’ll outline some handy tips around unlocking your phone. We’ll also talk you through the major UK networks’ policies, so you'll know exactly what you've got to do to get your phone unlocked.
Getting your phone unlocked? In the market for a good SIM only deal? Here's our pick of the best SIM only deals around.
How do I unlock my phone?
If you want to unlock your phone, you have two options.
One way is to take it to a local, independent phone shop which will usually charge you a fee of around £15 for the service. It might be worth checking its reputation online beforehand, just for peace of mind.
Another method is to do it yourself by getting hold of a code or using a special data cable and software. However, you do need a fair degree of technical know-how to do so.
Is it legal to unlock my phone?
It’s not illegal to unlock your phone with either of these methods. However, in both cases you risk invalidating your warranty with your initial network.
But the safest and smartest way of unlocking your mobile phone at home is to call your network and ask them to unlock it.
Whether a charge will apply and how fast and readily they’ll unlock it depends on your carrier’s policy. We'll take a look at all the major networks' policies below.

I'm going to unlock my phone via my network. How does it work?
When you contact your network to unlock your phone, they'll ask you for your IMEI number. This is an identifier that’s unique to your phone and enables your network to discern make and model, as well as its serial number.
You can get the number in a variety of ways. But perhaps the easiest is by opening the Phone app, then entering *#06# using the keyboard. The IMEI number will flash up on the screen instantly for you to take down with a piece of paper. Or with your phone’s Notes app.
Alternatively, if you’ve got an iPhone you can find it via your Settings app. First open up Settings, then tap ‘General’, followed by ‘About’. You’ll find it towards the bottom of the screen.
Got an Android phone? You can also get your IMEI through the Settings part of your phone. Once you’ve opened Settings, go to ‘About Device’ and then ‘Status’. And there you’ll find it.
Once you’ve provided your network with your IMEI, they can start the unlocking process.
How long it’ll actually take and whether a charge applies depends principally on your network’s policy. However, it’s also affected by whether you’re a pay monthly or pay as you go customer and by the make and model of your phone.
We examine each major network’s policy on phone unlocking further down the page.
Is my phone locked? How can I find out?
It’s simple to find out if your phone is locked. Simply insert a SIM card from another carrier (you’ll be able to get one free from a phone shop or by ordering one online) and see if the name of the network appears on your handset.
You could also ask a friend or family member to borrow theirs to test it out, as long as you're safe with it and return it in working order.
If the network appears and you’re able to use your phone, it’s unlocked.
What does it mean when a phone is locked?
When a handset is locked, it means it will only work with the provider that you bought it from.
If your phone is locked, it won’t automatically become unlocked when your contract expires with your provider.
What are the benefits of unlocking my phone?
A Uswitch survey revealed that Brits spend an incredible £48 million per year on unlocking mobile phones.
Not only does an unlocked phone let you take advantage of cheap SIM only deals across the entire range of networks. It also makes it easier to pass on your old phone to a family member or friend.
When your phone's unlocked, you're not limited to tariffs offered by the network you bought your phone from. You can take your pick from the whole market.
Just as important is that really good SIM only deals tend to be up for grabs for a limited period only.
Having a SIM only deal gives you the freedom you need to chop and change and snap up the best offers while they're still around.
Why should I unlock my phone?
Many people unlock their phone when they want to sell it. Generally unlocked phones command higher prices and sell faster than those that are still tied to a network.
If you're a frequent traveller and want to save money on roaming charges by using SIMs from overseas networks, you'll need a phone that's unlocked.
Can I unlock my phone for free? How long does it take to unlock my phone?
Uswitch's survey into phone unlocking revealed that the time it takes to unlock a phone and the price you should expect to pay is one of the areas where Britons are most confused.
That was borne out by the finding that almost one-third of consumers think that unlocking a phone will be instant.
In reality, what it takes to get your phone unlocked depends on your provider. But you should be mindful that you could be waiting for anything between a few days or up to 30 days for the process to be complete.
