Find out how to unlock your phone so that you have the freedom to roam any network you like.

What does ‘unlocking’ mean?

Most mobile phones, when you buy them, will be linked to a particular network such as Virgin, Vodafone, or Orange. This means that the SIM card that comes with your new phone is ‘locked’ to that network and will only work on the network it has been assigned to.

If you swap your SIM card for one from a different network, it’s likely your phone won’t function. This means you can only use services provided by the network you originally bought the phone with.

By unlocking your phone you’ll be able to use it on any network you like, meaning you may be able to get cheaper calls and texts, call abroad for less, and take advantage of network-specific deals such as Orange Wednesdays.

Unlocking your mobile gives you the freedom to explore different networks and their associated benefits rather than remaining with the same network until you buy a new phone, so that you can make using your phone even cheaper.

How do I unlock my phone?

It might be worth reading our guide: Unlocking your phone for network-specific instructions.

First of all it’s a good idea to check whether your phone is currently locked to a particular network. You can do this by inserting a SIM card from a different network into your phone and switching it on.

If the phone works as usual then there’s no need to unlock it and you can enjoy using different networks right away. However if your phone doesn’t switch on or displays a message like ‘Phone locked to network’, then it means you’ll need to go about unlocking it.

One of the first things worth doing is simply calling your existing network provider, and letting them know you want to unlock your phone. Under Ofcom regulations you have the right to unlock your mobile if:

  • Pay as you go: the phone is over a year old.
  • Contract: you have reached the end of any minimum term contract.

You’ll usually have to quote your mobile number, your manufacturer and model number (which can be found on the outer case of your phone) and your IMEI number (a serial number which can be found by typing *#06# into your phone). You also may have to give up to a month’s notice to your network provider, and pay an unlocking fee of up to £30.

Your network provider will then give you an unlocking code (also known as a PAC - Porting Authorisation Code) which will allow you to transfer your number from one network to another and will unlock your mobile from its original network.

When you put a SIM card from a different network into your phone, type this code into your keypad to unlock it and access any network you wish.

What else should I consider?

There are other ways to unlock your phone in addition to phoning your network provider and asking them for a code. Several websites provide free unlocking services, although it’s worth noting that not every kind of handset will be covered and you may not be able to find a code for your phone.

Alternatively you could use an online mobile phone unlocking service such as which will provide an unlock code in a matter of minutes.

You can also pay a fee of around £10 to get your phone unlocked on the high street, either at an outlet dedicated to this service or at your local phone shop, but it's worth shopping around to get the best deal.

If you’re thinking of unlocking your phone it’s worth making sure that the fee you pay to unlock it will be outweighed by savings you’ll make by having the freedom to switch networks, otherwise it may be best simply to stick with your current network.

You can take your pick of the free SIM cards available at the moment and start enjoying your new network as soon as the phone is unlocked. If you’re planning on using a new SIM card in your phone, it’s worth saving all the contacts and data from your old SIM to your phone, so that you can transfer all your data right away.

It’s worth noting too that if you have a warranty on your phone, unlocking it will usually invalidate this, so this is something to consider if you’re still within your warranty period.

I have been trying to get an unlock code from Orange for 6 weeks now. I don't mind the fee that they charge, but I do mind that they seem to be playing the waiting game. I have contacted them via email, by phone, by letter, via facebook, and I am just getting no response. Lots of promises to call back, to get things done, and to respond, but that's it. They are just not doing it. Do I have any options left? (Unfortunately the usual unlockers are not able to unlock the Orange San Diego.)

If an iPhone is locked to a server, say 'Orange, would you be able to use other Orange SIM cards in that iPhone? Or would the iPhone be locked to that specific SIM card?

Bad info. A PAC does not ' unlock your mobile from its original network'

by kmofo, 29 Jun 2013

The guide made it quite clear that this was for moving networks, as it clearly stated that the PAC code "will allow you to transfer your number from one network to another and will unlock your mobile from its original network".

by Bonz1957, 29 Jun 2013

No, a PAC code has nothing to do with your mobile. It is about moving your phone number. A PAC code enables you to move your phone number from one network to another. Your phone number is nothing to do with your mobile; it is attached to your SIM card and the SIM card only ever works on the network you got it from. The PAC code enables a new network to attach that phone number to one of their own SIM cards. If your phone is SIM locked, it will still be SIM locked to that network after you have ported your number with the PAC code. And you won't be able to use the SIM from your new network in it. If your phone is SIM locked and you want to move networks, you need a PAC code to move your phone number, and a SIM unlatch code to unlock your phone.

ptk is absolutely correct. Do not mix PAC code and UNLOCK codes. They are two totally different things.

They have no legal rights locking a sim free phone to any network, if you have brought the phone outright. I.E so you can swap sim cards when ever you want.

I do not know what network my phone is locked to

by madhea60, 24 Sep 2013

in france the same company, Orange, give you the unlock code over the phone and all providers are obliged by law to let you have your phone unlocked free of charge after 6 months into your contract. It creates a much more competitive dynamic market. The UK should learn !

£10.79 !!!!!!! thought was supposed to be £1.99 as clearly stated below!?!

I want to anlock phone

by kastri, 2 May 2014

I hve been waiting for an unlocking code from Orange for 9 weeks. They took the fee shortly after I made the first request. I have tried to use their complaints procedure, working through the stages set out with no success so far. I am looking at using CISAS next.

Hi Applesnpears, Is the phone that you have a PAYG or a CONTRACT PHONE-- (I have contract)
The next time that you contact them start your call with something like
It is.... on .... as soon as the operator answers,---
with actual time and date of your call
ask them for the "ADDRESS TO SEND ANY LEGAL NOTICES TO THE COMPANY" as you want to make a claim.
as you have paid for the service tell them that they have borrowed your money since (whenever they debited your account )or you made the payment
"You have borrowed my cash for days -
(the number of times that you COULD have actually paid a fee per month) to borrow the cash
I am preparing a claim from....(DATE OF PAYMENT) until this is received at £.......(EACH MONTH)that I need to wait until I receive this.

Try a bit of BS like above mate and see if you get a better reaction from them.
If possible ,and your friend has a mobile with "UNLIMITED or a lot of minutes that are not used
THAT IS REGISTERED WITH A COMPETITOR NETWORK ask if they will let you call ORANGE with that (not EE or TMOBILE as same group)
it will look as if you have already got a DIFFERENT number as it will show up on their screen that it is not for the number that you are wanting UNLOCKED (contract mobile)
Personally, I waited 6 months for this and threatened them with a bill off £180.00 (30 per moth- a pound a say) for the rollover costs. -
After my HEAVY HANDED call like the above- I eventually received this code from them in a few days
Also they may try and delay this by
saying that the code for your particular model has not yet been issued by the manufacturer if a latest model
