iPhone Unlock Software

Apple's free iTunes software can be turned into iPhone unlock software to unlock your iPhone from AT&T permanently but it only works if your iPhone is registered for unlocking through our paid unlock service (UnlockStreak Activations for iTunes). Once your iPhone is registered for unlocking, connect your handset to iTunes and our unlock service unlocks your handset directly through the iTunes software. Once finished, you can use your iPhone unlocked on any network that uses SIM cards. For example, unlock it from AT&T to use it on T-Mobile or on any other network service provider worldwide. By using our unlock service through iTunes, the warranty will be maintained because there is no alteration of the software on the phone. The phone will stay unlocked permanently regardless of firmware and software updates.

This works only for the iPhone locked to AT&T, USA. It does not unlock the iPhone locked to a different carrier.

What Is iPhone Unlocking?

When you purchase an iPhone from AT&T, it comes locked to the carrier so it works only with their specific SIM card. The only reason to lock the phone is to ensure you use their service for an extended period of time. If you attempt to use an alternative SIM card in a locked phone, you will receive an error message such as "Wrong SIM Card" or “Different SIM detected. Please connect to iTunes” or similar. iPhone unlocking enables you to use your mobile phone with a SIM card from any carrier. Once the device is unlocked, the error message is removed and you are free to use the SIM card of your choice.

Unlock Method:

The UnlockStreak Activation for iTunes unlocks your AT&T locked iPhone permanently. There is no jailbreaking involved. It works for all firmware and baseband versions. Your phone will never relock even if you update or wipe the device. It is required that you connect your handset to iTunes and use our unlock service, which unlocks your handset directly through iTunes.

Unlocking Benefits:

There are many benefits to unlocking your iPhone, including:

  • Ability to use any SIM card from any network 
  • Save money by choosing the cheapest available carrier
  • Switch to a carrier that offers better service
  • Travel and use cheap local SIM cards rather than your native SIM card, thereby avoiding high roaming fees
  • Make money by selling your iPhone unlocked (unlocked phones have a higher resale value than locked phones)

Phone Requirements:

  • Must be locked to AT&T
  • Supported models: Apple iPhone, iPhone 3G, iPhone 3GS, iPhone 4, iPhone 4S, iPhone 5, iPhone 5S, iPhone 5C

Computer System Requirements:

  • MAC or PC running the latest iTunes software


  • Is there any risk? Your device is at no risk. The unlocking can technically not damage your phone.
  • Will the warranty be maintained? Yes because the unlocking is done without any alteration of the phone’s software.


Part 1/2: Prepare For iPhone Unlocking

Before You Start

You will need a USB cable to connect the phone to the computer.

Check that your iPhone is locked to AT&T. Our unlock service works only on Apple devices locked to AT&T. If you are in doubt, send your IMEI to support@unlockstreak.com and we will check the carrier for free before you order the unlock. The IMEI can be found engraved on the back metal case (original iPhone) or on the SIM tray (all other iPhone models).



Part 2/2: Unlock Instructions

Step 1

After you’ve received the UnlockStreak Activation notification by E-Mail from us, install the latest version of iTunes on your MAC or PC.

If you haven’t ordered an iPhone unlock yet, please do so on our website:

Download the latest iTunes version:

Step 2

Open iTunes on your MAC or PC and verify that you have Internet connectivity.

Step 3

Connect your iPhone to iTunes by USB cable. Update your iPhone to the latest firmware. In case your iPhone has never been activated or connected to iTunes, you might get a (red) error message. In that case, unplug and replug the phone.

Step 4

Back up your iPhone:

  1. Connect your iPhone to the computer running iTunes
  2. Select your iPhone device in iTunes under Devices
  3. Right click (or Control click) the device and select Back Up.

Step 5

Erase the contents of your iPhone:

  1. Make sure that the battery of your iPhone is fully charged! If it isn’t, connect the device to power and leave it connected until the process is complete.
  2. On your device, go to Settings > General > Reset and select “Erase All Content and Settings”. The process can take from a few minutes to several hours.

Step 6

You can do the unlocking either with an original AT&T SIM card, or with a non-AT&T SIM card, or without any SIM card inserted. If you insert a non-AT&T SIM card before the unlocking, iTunes will display an unlock confirmation message once your iPhone is unlocked. If you use the original AT&T SIM card or no SIM card at all, iTunes will not display any unlock confirmation message but your phone will still be unlocked.

If you'd like to exchange the AT&T SIM card with the one for the new carrier, visit the following website for help on swapping the SIM card: http://support.apple.com/kb/HT5163.

Step 7

Restore your iPhone and iTunes will run the UnlockStreak Activation to unlock your phone. To restore your backup, follow one of these steps:

  • With your iPhone connected to the computer running iTunes, Right click (or Control click) the device and select Restore from Backup

  • Alternatively, if you have a new iPhone, you can connect to iTunes and it will prompt to restore from your backup. 

Step 8

After the unlock process has finished, disconnect your iPhone, wait 10 seconds, then reconnect to iTunes. Finished! Your iPhone is now unlocked for use on any compatible network. It will never relock even if you update or wipe the phone. Enjoy mobile freedom.
