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 Sonofon. This is when an Official Factory Apple Unlock Service is required.

An Official Apple Unlock removes ALL network restrictions imposed by Sonofon both in and around the world. This allows your iPhone 3Gs to be used with ANY network and unlocked from anywhere in the world. Unless stated, as long as your iPhone 3Gs has not been reported 'lost or stolen', any iPhone 3Gs 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 Sonofon in .

To unlock your iPhone 3Gs 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 Sonofon 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.

How to unlock an iPhone 3Gs on Sonofon:
  1. Locate your IMEI number (Detailed help on how to find your imei is available here)

    Totally confused by all the sites claiming to be able to unlock my iPhone. I asked a few questions and was directed to an info page which listed a lot of the scam tactics used by these sites and what to avoid, I immediately new I had been just one click away from losing my money. Please Will, post the link in the comment on this post because I cannot find it and found it very enlightening. Great service, absolutely fantastic customer communication. Can't recommend enough.

    I found cheaper unlocks but not on sites that instilled any confidence in me. I spoke to LiveChat to eliminate any doubts I had and made my order on Monday lunchtime. The service was quoted at 13 working days but I had my unlock confirmation the very next day. Clear and simple instructions to complete the unlock. My phone is an iPhone 4s which WAS locked to O2... not any more!

    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.

    I'd used this site before to unlock another phone but this time I wanted my new iPhone 6 plus unlocked. It took a little longer than I'd hoped so I was getting a little worried. I had no problems with my previous unlock so I knew it wasn't a scam but others in the same position may have worried. I was probably a little impatient because it was only 2 days later than I thought.

    Cheaper and quicker than most others, I thought there must be a catch. How wrong was I!

    I was referred to this site by my friend so was already confident that this was not one of the many scam sites out there. They did exaclty what they promised and unlocked my phone from Vodafone very quickly. I now too, can confidently recommend this service and its results. Simply don't go anywhere else!

    Spent about a week being told by local shops and Vodafone that I could not get unlocked, I thought I was stuck with an iPhone that I was never going to get unlocked. Found officialappleunlock this morning and within a few days it was unlocked. Seriously impressed and can highly recommend to others.
