Official Factory Unlock for iPhone 4S

Factory iPhone Sim Unlock for all models, basebands and firmware

Lowest Price in the US - price match* guarantee

Applied using iTunes - warranty remains valid

Permanent - always upgrade to the latest version of iOS

No need to jailbreak - once you've made your purchase, simply connect your iPhone to iTunes to complete the unlock.

What firmware and basebands can we unlock?

We get asked this all the time on our Facebook page - because we sell official carrier unlocks and not software hacks, what firmware and baseband you have is unimportant - we can unlock ALL firmwares and basebands (including 04.11.08, 04.12.02, 05.16.05 etc), now and new ones which come out in the future. The only important question we have is 'what network is your iPhone locked to'.

We will email you once your iPhone's IMEI has been processed by Apple, then you simply connect your handset to iTunes to complete the unlock. You will then be able to use the handset on any network worldwide.

Device Details

Purchase our £4.00 Network Check Service if you don't know what network the handset is locked to.

  1. Important: You must select the network the handset is currently locked to, however any sim card will unlock the device.

    Don't select the network you want to run it on - as once unlocked you can go on any network.

Select your handset
and network

Please note that purchasing this service alone will not unlock your device.

This service simply tells you what network it is locked to so you make a correct unlock purchase.

IMEI Number

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.

Please do not give us the IMEI written on the box, as boxes are often switched. If unsure, simply put TBA and we will help you find the IMEI after purchase.

  • This does not appear to be a valid IMEI - Please check you have typed it correctly. It should be 15 digits in length. If you are not sure just put TBA.
