Why you can unlock your phone for free in the UK
If you’re stuck with a phone that only works on one network, here’s the good news: since December 2021, UK mobile networks have been banned from selling new phones locked to their network. That means you can unlock your phone for free, and it’s usually far less hassle than people expect. This guide covers your rights, how to check your phone’s status, and the exact steps to unlock your phone today, whether it’s brand new or a handset from a few years back.
Ofcom, the UK’s telecoms regulator, brought in the rule as part of a wider push to make switching provider simpler. Before then, some networks (including BT/EE, Vodafone and Tesco Mobile) sold locked handsets as standard, while others such as O2, Three, Sky Mobile and Virgin Media had already moved to unlocked devices. A locked phone used to put people off switching altogether, and Ofcom’s own research found it deterred a sizeable share of customers from even trying.
Is my phone locked to a network?
Possibly, especially if you bought it on contract before December 2021 or picked it up secondhand. The quickest check is to pop a SIM card from a different network into your handset. If it connects and shows signal, you’re unlocked already. If you see a message asking for a network unlock code, it isn’t, and you’ll need to unlock your phone before a new SIM will work.
On many Android phones you can also check under Settings, then About Phone, then Status, where a locked handset often shows “SIM lock: ON”. iPhones don’t display this quite so clearly, so trying a different SIM or asking your network directly tends to be the fastest route.
You’ll need your phone’s IMEI number for most of this. Dial *#06# on the keypad and it appears instantly, or find it buried in your settings. If you’re buying secondhand, it’s also worth learning how to check a phone’s IMEI number for signs of loss or theft before you commit to anything.
How to unlock your phone for free, step by step
Contact your current network and ask for an unlock. Every major UK network, including EE, O2, Vodafone, Three, Sky Mobile, Tesco Mobile and Virgin Media, has to do this free of charge under Ofcom’s rules. You don’t need to be out of contract, and you don’t need to have paid off a handset plan, to make the request.
- Find your IMEI number by dialling *#06# on your phone.
- Log into your network’s app or account, or call customer services, and ask to unlock your phone.
- Confirm your identity if asked, usually your account details or a quick security question.
- Wait for confirmation by text or email, then restart your phone with a different SIM inserted.
If your phone was bought new from a UK network after December 2021, there’s a good chance it shipped unlocked already. In that case, you can skip straight to the SIM test above, since there’s often nothing left to do.
Got an older phone from before the ban, or one bought on contract years ago? You can still unlock your phone for free, it just might take a touch more back and forth. Networks must unlock any phone on request, whatever its age, as long as you’re the account holder or can prove ownership.
Phones bought abroad, picked up on old pay as you go tariffs, or handed down from a relative can all be unlocked the same way. If the original network no longer exists after one of the industry’s many mergers, your current provider’s customer service team should still be able to point you in the right direction.
How long does it take to unlock your phone?
Usually a matter of days, though it does vary by network and handset. Some unlocks happen almost instantly through an app or online account, particularly for newer phones. Older handsets that need a code from the manufacturer can take closer to two or three weeks in slower cases. Whichever route you take, most people manage to unlock your phone within a week, sometimes the same day.
If your network drags its feet well past a reasonable timeframe, you’re entitled to complain. Don’t just sit and wait it out; a polite follow up, and a formal complaint if needed, usually gets things moving.
Why unlocking your phone actually helps you save
Once your phone is unlocked, you’re no longer tied to one network’s tariffs. You’re free to shop around, compare SIM only deals, and pick whichever network offers the best mix of price and coverage for you. If you decide to switch mobile network and keep your number, unlocking your phone is normally the only technical hurdle standing in your way.
An unlocked phone also holds its value better if you sell it or pass it on later, since whoever buys it isn’t limited to a single network either. It’s a small job with a genuinely useful payoff.

Frequently asked questions about how to unlock your phone
- Do I have to pay to unlock my phone?
- No. Since December 2021, UK networks must unlock your phone for free on request, whatever your contract status.
- Can I unlock a phone I bought abroad?
- Usually, yes. Contact the original network with your IMEI number, and if that’s not possible, your current UK network may still be able to help.
- Will unlocking my phone delete anything?
- No. Unlocking only removes the network restriction. It won’t touch your photos, apps or settings, though backing up before any phone change is always sensible.
- What if my network won’t unlock my phone for free?
- That would go against Ofcom’s rules. Raise a complaint with the network first, then escalate to an ombudsman if it isn’t resolved.
- Does unlocking mean my phone works on any network worldwide?
- Mostly, yes. Very old handsets can occasionally have regional restrictions unrelated to network locking, so it’s worth checking compatibility with your new SIM just to be safe.
