iPhone

Pantech
Samsung
Sony Ericsson

Apple

Open iTunes on your Mac or PC and verify that you have Internet connectivity.
Ensure a SIM card that is NOT from the original carrier is inserted into your iPhone.
For example, if your iPhone is locked to AT&T, insert a T-Mobile, Verizon or any other foreign SIM card.
Connect your iPhone using the USB cable that came with your iPhone.
Your iPhone is now UNLOCKED!

AT&T Apple iPhone

To complete the unlock, simply follow the instructions below: (WORKS BEST WITH AT&T ACTIVE SIM CARD IN PHONE). If you phone is activated, you can use ANY SIM card.
Make sure you update the phone to the latest iOS version as older ones may not work.
**SPRINT/VERIZON phones are not supported!****

1. Make sure you have the latest version of iTunes installed. Make sure there is an active SIM card inserted in phone.
2. Open iTunes on your MAC or PC and verify that you have Internet connectivity.
3. Connect your iPhone to iTunes by USB cable.
4. Back up your iPhone. How to back up: http://support.apple.com/kb/HT1766
5. Complete the setup assistant and restore your backup
6. After the process has finished, disconnect your iPhone, wait 10 seconds, reconnect to iTunes. It’s fully unlocked now!

How can I tell my phone is unlocked for sure? Best way is by putting in a GSM (non-AT&T SIM) and seeing if you can dial out. Usually after restore process it will alert you that the phone is unlocked as well too. iTunes will not always show a message showing the phone is unlocked, so testing it with a foreign SIM is best bet.




iPhone Unlock Troubleshooting Guide


I ordered the iPhone unlock and received the confirmation email but my phone is still locked.

Have you followed the instructions in the email? Did you make sure to perform a full restore in iTunes? Have your tested your phone with a non-AT&T SIM card?

If you answered “Yes” to all of the above questions and are still having problems then read below.

1. My phone shows “no service” while trying to use it with a T-Mobile/Simple mobile SIM.
The number one reason for that issue is a bad SIM card. Get a brand new, 64k or newer SIM card and contact your carrier to ask whether your iPhone is registered on their network. We will NOT be able to help you because this is strictly a network issue and has NOTHING to do with the unlock.
If the problem persists – contact Apple to see if the phone is defective and can be swapped.


2. My phone would not activate in iTunes.
If you have iPhone 3G or 3GS that has been previously unlocked with Cydia/Redsnow then it probably has a non-standard modem firmware. Check your modem firmware by going to Settings -> General -> About -> Modem Firmware.
If it shows 6.15 then it cannot be unlocked without downgrading first.
Check out this YouTube version on how to downgrade: http://www.youtube.com/watch?v=srrXFHRZH9U


3. My phone displays “Invalid SIM” and won’t work.
Contact us about this issue and we will look into it.


If your phone is not unlocking or getting signal, PLEASE perform the backup/restore once again (above). Sometimes it takes upto 3 times to get it provisioned and unlocked. Also another solution is also trying to do another restore on another computer. Many times this has done the trick too.

Also if your phone is JAILBROKEN thismay not work due to the software being altered. Make sure your phone is NOT 06.15.00 (iPad) Baseband. If it is you will have to downgrade to the correct baseband. You can check YouTube or Google how to do this.

What if your phone shows up as NOT ACTIVATED?

You need to use an AT&T active SIM card to activate or get the last owner's billing ZIP code & last 4 of their SSN. Please make sure you DON'T confuse UNLOCKING with ACTIVATING. These are two different things.

Prerequisites to check before proceeding:

  • Downgrading procedure will delete all your data stored on the internal SD card. Make sure to backup your data, and any installed apps.

  • Charge your device’s battery to the full.
  • Enable USB debugging option by pressing Menu > Settings > Applications. Navigate and tap on Developer Options to ensure that USB Debugging is enabled.

How to downgrade firmware on Samsung Galaxy Devices:

Required files: download the firmware file that you want your Galaxy device to downgrade to. One good source for downloading Samsung firmwares is Samsung-Updates.

  • Extract the downloaded firmware on your computer.
  • Download Odin Firmware Flasher and unzip it. Using Odin 1.85 version for installing older firmware and using Odin 3.04 for newer ones is recommended. Download the relevant ones from these links: Odin3_v1.85.Zip OR Odin3_v3.04.Zip.
  • Switch off your Galaxy device and boot into Download/Odin Mode. If it is a Samsung Galaxy phone, you can do so by pressing and holding the Volume Down + Home + Power buttons simultaneously until the screen turns up.
  • Go to the Odin folder and run the .exe file there.
  • Connect your Samsung device to the computer using a USB cable. When the connection between the device and computer is established, the ID:COM port at Odin screen will show you an Added!! message.
  • Make sure that only F. Reset Time option is checked on Odin. Uncheck the Auto Reboot option which is checked by default.
  • Next, click on the PDA button on Odin and select the firmware file in tar.md5 format.
  • Press START on ODIN to initiate the firmware installation process. The process will take a few minutes. When it’s completed you’d get a PASS message on Odin.
  • Disconnect the device and remove the USB cable.
  • Open the back panel of your device and pull out the battery. Wait for some 60 seconds and reinsert the battery back.

Release the power button but keep the other two keys pressed until you see a black screen with green Android bot and blue text. For Galaxy Tab or Note 10.1 >> press and hold the Volume Down + Power keys together for a few seconds until you see the yellow triangle with Android bot followed by a black screen with blue text.
  • Once in recovery mode, use the Volume Up/Down keys to scroll up or down, and use the Power button to select any option.
  • Perform the wipe operations by scrolling down to wipe data/factory reset option and select yes to confirm the process. Next, go to wipe cache partition and confirm it.
  • Once done, go to the reboot system now option to boot your Samsung Galaxy device into the older version.
