  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).

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.

We got approximately 50 business iPhone 4s and 5s devices unlocked through Officialiphoneunlock. Devices were locked to O2 UK. In a marketplace where there are many 'shady' companies offering 'unlocks' for a lot less I was very suspicious but after reading other reviews I decided to take the plunge with a couple of devices at first. On the positive side I will say that they are 100% trustworthy and they completed all unlocks as advertised. I also accidently put through an 'advance order' mistakenly for T-Mobile which would have eventually cost £100 but their Customer Services team contacted me to highlight this and they cancelled the order. I thought this was really good. One the slight negative side (and the reason why I wont give 5 stars) is that all the unlocks took 4 days at best and 6 days at worst. The 'average' timescales given at POS was 24-48 hours. We did 7/8 separate orders, some for just one each and one bulk order for approx. 30. They all took 4-6 days. I would say to Officialiphoneunlock that if 4-6 days is really the timescale to expect then please be honest with customers and say this at the start on your website. Thanks again, I wouldn't hesitate to recommend your services, but I would tell people it will take a little longer than advertised.

Yes the unlock process worked as described. Just had a bit of trouble with ITunes store and access to it, but solved by 1 - Authorise this computer 2 - Edit Preferences, Parental and checked "allow access to iTunes store and to ITunes U"

Got an iphone 5s from uk and it was locked by O2 UK. As I am currently living in Brazil, I decided to buy the unlocking service from this site. First time I was doing this, I gave the website a chance. After 6 days, got an email saying my phone was unlocked on apple`s database.

I turned the iphone on, connected it to a wifi network...and voilá! Beautifully unlocked and working in a brazilian carrier. No itunes was needed.

Good job guys. Will recomment.

The unlocking procedure was really straightforward. Support told me that I would be able to unlock my iPhone online and ran through briefly how to do it. After submitting the relevant info to the web-site and paying for the service, I waited just one day for the unlock to be actioned. I then got my iPhone ship-shape by logging into iTunes. The service provided by OfficialiPhoneUnlock was excellent, and I would recommend this firm wholeheartedly.

I have used on a number of occasions to unlock customer handsets from O2/Vodafone & Orange, from the iPhone4 up to this iPhone 5S. The service is excellent and I am kept fully informed throughout the process. I have and will continue to use for all future unlock solutions regarding the iphone. I have also advised my customer that they also use them if they should have a number of handsets that they require unlock.

My iphone 5 was locked to O2 UK, it was sent to me by my cousin in UK, so i tried all means to have it unlocked but to no avail, finally i got to hear about this site:,
I so much wanted to have my iphone unlock, so i can use it on any network, I was reluctant to make payment but the person who told me about the site assured me I had nothing to worry about, so i went ahead to make payment.
After making payment, I was told it will be unlocked within the time frame of 5-15 days, after few days i was contacted through my email that my iphone IMEI is blacklisted, and that i can still have it unlock if i follow the link sent to me and complete the payment for black listed IMEI, since i wasn't charged for that services. Again I gather courage and completed the payment, also i contacted the support team and they responded quickly assuring me that my iphone will be unlock asap.
And just like i was told, in few days time i received an email that made me smile all day,, it says that my iphone has been unlocked and i should follow the directions to start enjoying my iphone, so i connected to itunes and started enjoying my iphone 5
I will use this services again and again, I have also given my friends and relatives this site to unlock their iphone and they were so happy with the services. Thanks

Had my iphone 4s unlocked from O2 in the UK so I could use it here in Denmark on Lebara, within a couple of days..I was sceptical to start with as I had never before had a phone unlocked online, but after reading reviews on FaceBook tried it and very happy with the service, unlocked over the weekend for a lot cheaper than me sending the phone to England and getting someone there to unlock it. Very happy and highly recommended.

I got my unlock in 72 hours (quoted time 24-48 hours)
I did have to contact support once because it was taking longer than the quoted time but as soon as I contacted them, I had my unlock quote within 3 hours.
The service did meet my expectations.
I would use them again, and reccommend them to my friends.

My wife's phone was locked to o2. We spend time both in the UK and Spain. By unlocking an iPhone and using a dual sim case means we do not need to carry two phones, or mess about switching sim cards between phones. I unlocked my phone last year, so this is our second purchase from official iphone unlock. Service is speedy and efficient. Highly recommended.

Went to OfficialiphoneUnlock as I wanted a renowned service, not a backroom special with dodgy jailbreak software, or an ebay service of questionable repute. Service was smooth and clear, took 3 days to unlock my iphone 4S - now it is in use fully on the required network and working well. Would definately recommend to other iphone users wanting an unlock service. Maybe slightly more expensive than some but worth it in the end. Some of the American sites were VERY expensive as the phone is for the UK market so this UK company was ideal. A++++++++

My son had an iPhone 4 locked to O2 -when he upgraded he gave the handset to his younger sister. Not being a customer of O2 and being unable to access the network the only solution was to have the phone unlocked. Being a technophobe - an acquaintance recommended I try this site. I did and having messed up providing incorrect identification number and paid my money was distraught to discover the phone was not unlocked. I contacted Official iPhone unlock and was amazed at how helpful and understanding the telephone operater was, to the extent that even though it was my fault for providing the incorrect number the company discounted the next attempted unlocking - which I am pleased to say worked and enable my daughter to use the handset within 48 Hrs. One very satisfied and wiser customer.

Such a pleasure to use this service. My phone could not be unlocked using the conventional service so OfficialiPhoneUnlock advised me on other services I could use and also advised me on possible problems with some networks after unlock. My phone is still happily unlocked and working fine even after apple updates. A one time service that lasts a lifetime of the phone.

Highly recommend

I bought an iphone 4 from ebay and took it to India for my friend. It turned out that it was locked, but I didn't realise till we were back in the UK. I contacted OfficialPhoneUnlock (actually whilst I was sitting at Gatwick waiting for another plane!) and did the necessary - my friend in India emailed to say that within 4 days (quicker than expected) he could access the phone. The only annoying thing was that we tried to do it by phone and held on for 20 mins, but in the end (as time was running out) my husband managed to do it online, which was successful. Next time we would do it online.

I got my new iPhone and it was locked. I submitted my phone to be unlocked and there was a problem as the phone had never been activated with any SIM card.. Support told me what I had to do and within a few days my phone was open and ready to use with any SIM card..
Cheaper than anywhere around me to open as well so it was worth the wait..
Would recommend to use this company..

Very good value, just give the details then sit back and wait for the phone to be unlocked. They do exactly what they say they will do.

Trusted service, would definitely use again. Recommended to all friends and family.

Waited for 13 days to get my unlock done. However, not the company's error as apple servers were down. Support team needs to reply ASAP regardless of the fact the company is unlocking 300+ handsets a day. That's not an excuse. If you are trading in certain hours, give a time limit to the customer for a reply back. Otherwise, I am happy that £99 worth spent here.

I ordered an unlock on a Friday and was resigned to waiting until at least the following Tuesday as the confirmation said 24-48 hours of normal working days. Therefore delighted when email confirmation came through on Sunday evening that my iPhone had been successfully unlocked. An hour or two later and I seem to be fully back in business with all apps etc restored thanks to iCloud - a much, much better outcome than I expected. Recommended without reservation.

I have to admit that I was a little sceptical at first given all the scammers out there, but i'm now overjoyed that I can now use my iPhone on any network!!

Since my iPhone was locked to O2 UK, i did have to wait for 10 days till the unlock arrived, but at least the website allowed me to check the status of my order any time I wanted. Also, it may be good to note that once you effect payment, the company will ask you to verify the order by sending a photo ID or at least the frontside of the credit card used to pay (card number covered) - it seems its just the company's way to ensure that they are not deaing with a scammer!!

Truly a wonderful service at a reasonable price!!

Will definitely recommend!!

Hi , guys. I am a monthly paying customer at O2 UK and I have asked them to unlock my iphone 4s. Of course, their answer was "safe into 72 hours", so I travelled abroad not worried what so ever. The problem started when I tried to use a local sim, and bottom line, I've spent 11 days calling them,2-3 times per day, every time getting the same answer. I have lost hope until a friend told me about this company.By then, I was so tired searching the internet for answers and getting so much info about scams. I looked at their website, seemed very professional, not like the ones seen before, so I purchased the unlock. It took 1 day and the only regret I have is that I haven't done that sooner. Thank you!

I bought my iphone 4 2nd hand with a gevey sim in it. As soon as i updated the IOS though, the gevey no longer worked and i was stuck with a brick for over two years! I didn't even know what the original telecom network was.
By chance, i stumbled upon the Official iPhone Unlock company website and after much musing decided to try them in hopes of finding out the original tele network and finally unlocking my iP4.
Official iPhone Unlock found my ip4's original network, so i went on ahead and requested for an unlock. First time around lucked out because apparently, my iP4 was in O2 UK blacklist! At this point i had more or less given up on an unlock. However, after some months of silence, Official iPhone Unlock contacted me last week and said that it's now possible to have my blacklisted brick unlocked. I was kind of skeptical at this point but decided to give it one last shot. Besides, should this fail, i get my money back. I got an email today saying that my iP4 is now unlocked. I followed the instructions, which were easy and painless an in less than two minutes my brick is now a fully functioning iphone 4! Finally!!!
Was the investment worth it? Most definitely! Official iPhone Unlock is the real deal. Thank you Official iPhone Unlock staff! You rock! Thank you very much!

Don't be out off by the price, at first I thought it was high but I requested my iPhone 4 on O2 (baseband 04.12.02) to be unlocked at 9pm on Thursday night, by 4pm Sunday afternoon (despite website saying they don't do it over weekends) the email came through to confirm the unlocking. Plugged phone into laptop and boom, signal immediately!

Thoroughly recommended! These guys are great!

Having 'shopped' around a little and using a cheaper product - that didn't work - I was somewhat sceptical about the claim to be able to unlock my phone. However, I needed the phone unlocked to go abroad and logged into Official Phone Unlock.
The service was prompt and worked perfectly with my O2 locked iPhone, in less time than estimated too. So, I am very definitely one very satisfied customer. Well done and thank you Official Phone Unlock!

My phone is iphone 4 locked by O2-UK carrier. I had tried many way of giving lots of money and no one able to unlock my phone. After couple of weeks they return the money.
But from site they done superb job to get my phone unlocked. There was a quite delay from my side to verify the CC details which I didn’t realize that it’s mandatory to do so.
Once verified the CC they just do it within two days that was amazing. Really was trustworthy…

Hi friends, My name Pranay, from India. I unlocked my iphone5 lock to O2 uk, through & its rock. really they are trust worthy guys. In the beginning for me it was hard to believe them but then I trusted them & paid all the money & they really valued for it & they unlock my iphone5 nearly after 15 days which was excellent. I rated them 4 stars because they are little bit expensive. If they reduce their cost 25-30% then it would be world famous unlockers.
But anyway, I'm totally impressed by them & planning to unlock more apples in the near futures
love u guys
Best Wishes

one thing is for sure as long as your phone has not been reported lost or stolen you will get your phone unlocked ...

in my situation my iPhone locked to o2 was promised to be unlocked within 24 hours ... it took a little longer and I think their time frames are very approximate but it was done and while a little frustrating I had to wait I can't complain too much at the service.

Would recommend highly especially for iPhones, the unlock is permanent as opposed to some software unlocks that will need re doing after a software update.

Excellent, phone was barred from UK O2 and this guys can unlock it from Factory, as they it will take time, but it will work end of the day. bit expensive though.

Excellent service

I was a bit unsure about using this service as there are so many spam companies out there but I can definitely say that they did unlock my iPhone 4S that was locked to o2 UK back in March 2013 and I have updated the firmware since with no problems at all so if you need to get your iPhone unlocked, Use these guys......

How we are different from the crowd

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.
