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 A1. This is when an Official Factory Apple Unlock Service is required.

An Official Apple Unlock removes ALL network restrictions imposed by A1 both in and around the world. This allows your iPhone 4s to be used with ANY network and unlocked from anywhere in the world. Unless stated, as long as your iPhone 4s has not been reported 'lost or stolen', any iPhone 4s 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 A1 in .

To unlock your iPhone 4s 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 A1 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 4s on A1:
  1. Locate your IMEI number (Detailed help on how to find your imei is available here)
  2. Select iPhone 4s from the model options.
  3. Select the Country your A1 iPhone is locked to.
  4. Confirm the A1 network by selecting it once the country has been selected.
  5. Order your iPhone Unlock - Instant submission upon payment.
  6. Unlock confirmation email sent immediately upon status update.
  7. Simply insert a new Sim card whilst connected to an active WiFi signal to complete the unlock.

The fifth generation of the iPhone family, the iPhone 4s which replaced the iPhone 4 and preceeded the iPhone 5 was announced on October 4, 2011 at Apple's Cupertino campus.

Availability of the iPhone 4 became available on October 14, 2011 in the United States, Australia, Canada, the United Kingdom, France, Germany, and Japan. The iPhone 4 sold over more than a million units in the first twenty four hours of going on sale and more than four million sales in the first four days of retail availability. 22 additional countries were added to the continual rollout on October 28.

This iPhone was named "4S" the ‘S’ depicting the introduction of Siri an iPhone 4S exclusive intelligent personal assistant which has since been included in the future generations of mobile Apple products. Retaining most of the external design of the iPhone 4, the 4S hosted major internal upgrades including an upgrade to the Apple A5 chipset and an 8-megapixel camera with 1080p video recording. It launched with iOS 5, the fifth major version of iOS and introduced a host of new features including iCloud, iMessage, Notification Center, Reminders, and Twitter integration.

It was succeeded by the iPhone 5 as on September 12, 2012. The iPhone 4S remained in production until it was finally discontinued on following the announcement of the iPhone 6. It was the last iPhone to have the original 30 pin connector as it was replaced by the Lightning Connector when the iPhone 5 was released.

    Was told by local shop that my phone could only be unlocked by Vodafone at an extortionate price and a 4 week wait. Chose www.officialappleunlcock.com web site after looking at many. The process was simple, quick and successful. I will recommend this site to anyone who asks about iPhone unlocking.

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

    My EE iPhone that is still in contract was unlocked in just 3 days when EE would not even enterain it. Bit expensive but less than I'd found elsewhere and the price was justified when it was explained to me that the handset is heavily subsidised when purchased on a contract.

    After trying 2 other companies on ebay, neither delivering and still chasing refunds, I was close to giving up. Of course the ebay services were a lot cheaper and that should obviously have been the alarm bell!! This service could not be more different, profession, fast and I could actually speak to a real person on live chat. Don't waste your time and money on cheap sites, they don't work. You get what you pay for! Brilliant

    I bought what I thought was an unlocked iPhone but they are not really unlocked!!I bought an unlocked iPhone 6 to take with us on our 6 months travels throughout Europe so that we could use local sim cards during our trip and avoid high roaming charges. I put my UK O2 sim in the phone and it worked fine but when we than came to put a French sim card in the phone it said Sim Not Valid!! After phone calls to Carphone Warehouse I was told that it would only work with the O2 network now! It's not unlocked then is it!!When I came across this service online the customer support girl explained everything clearly to me and the 'Next Tether Policy' whatever that meant? My only option was to unlock my handset and chose to go ahead because the timescale was so quick compared to other sites I'd seen. Took less than 2 days to get my phone unlocked and now I truly have an unlocked phone that will allow me to use any network.CAnnot thank these guys enough HIGHLY RECOMMENDED
