Unlock Three UK iPhone

  1. VERY IMPORTANT: This service supports all ESN - excluding Bad, unclean and Lost and Stolen

    This unlocks the GSM portion of the handset for international use. If you are based in the USA, it will still have to be used on Verizon(it won't work on AT&T for example).

Get started and enter your IMEI and Model

Your IMEI number is a 15-digit number unique to your handset. You can find your IMEI number in the Settings > General > About screen, or by dialling *#06#

If you cannot access this screen and you have an iPhone 4 or 4S then simply eject the sim tray on your iPhone. The IMEI will be printed on the sim tray - but please be aware that sim trays are sometimes switched.

If you have an iPhone 5, 5C, or 5S, the IMEI will be printed on the back of the iPhone itself.

Unlock possible - we can unlock this handset on all basebands, up to and including firmware 4.2.1.

I needed to unlock an iPhone 5 from 3 to be used on Vodafone. The process was fairly simple and about 4 days later the unlock code came through and the phone was swapped over without issue

Before I thought it might not be real but it is thanks good service on time delivery , my friend tried so many times on different side but he doesn't succeed and I found this side and watched customers feed back and in the end I made decision to go for it and I bought this service to unlock my friend phone as a gift :)

I purchased a used iPhone online, it was advertised as on Orange, when I tried it it didn't work, so I visited OfficialiPhoneUnlock to first find out what it was locked to, then have them unlock the iPhone. After just a couple of days, an email came to my inbox stating that my iPhone was factory unlocked, All I then had to do was connect the iTunes and a simple reset and it worked.
I would recommend this service, and use it again.

Except for one occasion, which was partly due to my own unreasonable expectation Every iphone that I submitted for unlocking achieved expected good result.

My iphone 5 was locked to 3 UK network. After extensive reserch, I chose these guys because they looked more genuine than the others (mho). The phone was unlocked within the time frame promised and I can use my iphone with the numerous international sim cards I have (as I travel a lot around europe).

I was stuck in Shanghai with an Apple replacement "unlocked" phone or so I thought. After many frustrating hours with Lebara and Apple I sought an alternative and found Official Phone Unlock on Google.
Firstly I bought the check service and found the phone was locked dispute numerous claims to the contrary from Apple chat on line.
Then I bought the full unlock service and "yippe" <24hrs later I had my service supplier back on line.
I am full of praise for this service and would highly recommend it should you require a phone unlocking.

They delivered exactly what they promised and ahead of schedule. Very easy to deal with and the comms were top notch. My only quibble is that £60 for unlocking an IPhone 4 is rather excessive in my view and they really ought to think about making these prices a bit more accessible to all especially kids.
Is is for that reason, and that reason only, they are not getting five stars otherwise it would have been 5 star***.

Had a change of heart 5 stars it is! :-)

Iphone locked to 3 UK, i got several opinions about 3UK all were negative that 3UK not giving unlocking provisions at all. Later i tried through, which was huge risk coz i paid amount in advance.

I was not sure whether i will get succeeded or not. After order, their timeline was 7 working days, to get it unlocked. I waited till 19th working day, lost all my patience, was waiting to put my complaint wherever possible. But got mail from them on 20th day saying 'your i phone is now unlocked' !!!!

Thanks in millions to the team (official iphone !!!!

PS:- For all users, please be patient, the time line may vary depending on the network, just wait.

I recommend using this site to anyone to get their iPhones unlocked, my iPhone was on three uk network which was a struggle to unlock but using this it unlocked after 8 working days though after it said it will do it in 7, I had to email them on the 8th working day and straight away got email back after couple of hours saying it will unlock, so waited for their email and replied back your iPhone is now officially unlocked, so overall I'm happy as its unlocked

I am pleased my iPhone 5 is now unlocked to all networks. The service was very fast as it only took 3 days. However, the price is quite high to unlock from three uk network but oh well I'm happy it's unlocked!
Would recommend!

These guys have a good service and a reasonable turnaround on email support. Looks like my phone provider (3 Sweden) was the worst of the lot! They have the costliest of all unlocks and still the unlocking did over 2 weeks. Nevertheless did come through in the end and my phone is unlocked!

How to unlock iPhone 4, 4S, 5, 5C, 5S locked to Three UK

Step 1: Simply enter your IMEI on the Buy Now page - using our direct connection to Apple we will tell you instantly what carrier your handset is locked to and whether it is locked to Three UK.

Step 2: The unlock price and timeframe will be displayed for an unlock for an iPhone locked to Three UK and you simply enter your email address (for the unlock notification when done) and enter your credit/debit card details.

Step 3: Once we have marked your iPhone as unlocked from Three UK we will send you an email, containing easy to use instructions on how to carry out the unlock - it's literally as simple as plugging your iPhone into your computer and iTunes will display a message telling you that your iPhone is now unlocked (see below). Alternatively, if you already have service on your iPhone locked to Three UK or have access to a WiFi network, the unlock will be applied automatically Over The Air.

How we are different from the crowd

  • INSTANT carrier checking - never buy the wrong unlock again - other sites make you wait hours if not days if you choose to check your carrier first, and also will refuse to refund if you choose the wrong network when purchasing an unlock. However with just your IMEI we give you everything you need - guaranteeing you are purchasing the correct product. We take the guessing out of unlocking.
  • The fastest unlock delivery (check the reviews!)
  • Telephone support which is actually answered rather than a recorded message going nowhere. Remember we aren't robots though and don't work 24/7 - please call us during UK working hours Monday to Friday.
  • Status of your unlock is updated hourly, from submission right through to unlocking.
