Unlocking policies with the various networks differ greatly. If you bought an iPhone 2nd hand or were gifted an iPhone, if you are not the original contract holder or if a contract period remains (to name but a few) it's likely you will not meet the requirements to unlock directly via Oi. This is when an Official Factory Apple Unlock Service is required.

An Official Apple Unlock removes ALL network restrictions imposed by Oi both in and around the world. This allows your iPhone 4 to be used with ANY network and unlocked from anywhere in the world. Unless stated, as long as your iPhone 4 has not been reported 'lost or stolen', any iPhone 4 can be unlocked, regardless of contractual period (unless stated) etc. Once unlocked you are able to swap and change network Sim cards at your will. Your will be unlocked to use any sim card and no longer limited to just Oi in .

To unlock your iPhone 4 with an Official Permanent iPhone Unlock all we require is the IMEI of the phone and a contact email address to receive all correspondence and ultimately, the 'Unlock Confirmation'.

An IMEI number is a unique 15 digit number that identifies your handset and its lock to the Oi network. The process updates your IMEI on the Apple GSX database and it is marked as 'Unlocked/Whitelisted/Sim Free'. This is the only permanent unlock, recognised by Apple.

  3. Select the Country your Oi iPhone is locked to.

The iPhone 4 was first unveiled on June 7, 2010 at Apple's Worldwide Developers Conference in San Francisco and soon after released in the United States, United Kingdom, France, Germany and Japan on June 24, 2010. It was the 4th generation of iPhone, at the time, succeeding the 3GS and preceding the 4S.

The iPhone 4 was the first of the iPhone range to include a front-facing camera and the first to be released in a version for CDMA networks, ending AT&T's period as the exclusive carrier of iPhone products in the United States.

At the time Apple claimed the iPhone 4 to be the thinnest smartphone in the World. The iPhone 4 also introduced Apple's new high-resolution "Retina Display". The iPhone 4 also introduced iOS 4 which included Facetime and multitasking.

It was succeeded as Apple's flagship smartphone in 2011 by the iPhone 4S. However, iPhone 4 continued to be produced until 2013.

All iPhone 4 models on networks that support Official Apple Factory IMEI unlocking can be unlocked with this service.

    I was in a hurry to unlock my phone and was bombarded with confusing websites. I found this site and could see they had lots of satisfied customers. The very next day I received my unlock confirmation and simply inserting a new sim card in to the phone, it was recognised and I have been using it without a problem since. The service was excellent

    From order to unlock I had no need to contact the company... that speaks volumes.

    I now have an official unlocked iPhone that I can use as normal without the need to worry about relocking, unlike the previous software solution I had to use. An offiical IMEI unlock is the only method I would recommend to anyone.

    Had a little problem with the phone recognising the unlock but emailed customer service and they soon determined it was because I had restored my phone to factory settings and not activated it before trying to unlock it. On their advice I solved my problem and now my phone is unlocked. The only reason for a 4 star and not a 5 was that LiveChat is only available 104 GMT and I am now in Australia. Already recommended to other travellers I have come across wishing to do the same and will continue to recommend you. Brilliant service, thank you.

    Took a little longer than expected but most importantly the unlock worked.

    I had been contacting Orange for over a month to try and unlock an iPhone I purchased on ebay without any success. After a further 2 weeks of waiting and getting nowhere I decided to look elsewhere. I was a little hesitant of the the reliability of an online solution opposed to an Orange shop but after purchasing the unlock I received confirmation of the unlock in just 3 days. Wish I'd done it right at the start!

    I looked at and compared a large number of unlock sites and in the end chose these guys. For the benefit of those reading this, I found their prices better or comparable with other services which was obviously the first factor but for those prices their unlock times were much quicker. Other sites advertise the same prices but some had unlock timescales 3 times longer than those offered here. I am glad to say that they delivered within their advertised times so I cannot praise more highly. Look no further if you need an unlock.
