How to unlock iPhone Devices
Please take backup of your iTunes before you start (for safety reasons of losing data)
Make sure you are using the most UPDATED version of Itunes
When your iPhone is unlocked you’ll receive a message from us , “UnlockAuthority stating that your iPhone has been successfully unlocked” Afterwards, follow the below instructions :
Please make sure that you are running the latest version of iTunes software on your computer. You can check it at http://www.apple.com/itunes/download
The next 2 steps are optional to unlock your iPhone, but these 2 steps will make sure that your iPhone is running the latest operating system software. If you do not have the original carrier SIM card or do not wish to update your firmware, please go to step 4.
2. If you’ve the SIM card from your original network (the network your iPhone is currently locked to), insert it. Connect your iPhone to your computer using the Dock Connector to USB cable provided with your iPhone.
3. Update your iPhone’s software in iTunes (It’s running the latest iPhone Operating System or iOS).
4. Insert a SIM card from a new service provider into your iPhone. It doesn’t has to be a SIM card from the network you wish to unlock – it can be any valid SIM card from ANY network provider (GSM SIM CARDS ONLY). Verizon & Sprint are not GSM SIM CARDS.
5. By inserting new SIM card, connect your iPhone to your computer and wait for iTunes to detect your phone.
6. Once it’s been detected, disconnect the iPhone from your computer and wait for 20 seconds or so.
7. Reconnect your iPhone to your computer and wait for iTunes to detect it again.
8. Once your iPhone is detected for 2nd time, the process is completed and your iPhone will be unlocked. After searching for few seconds, you’ll see your new carrier logo appear in the top left hand corner on the screen of your iPhone’s. This unlock is permanent and you can update your iPhone’s firmware at anytime. Some new devices such as iPHONE 6/6S might not show this. You can test with a GSM Sim card (to verify you get signal)
If you wish to see the unlock screen below within iTunes to confirm this is an official unlock, simply perform a restore within iTunes and once your iPhone is restored you will be presented with the message“Congratulation’s, your iPhone has been unlocked” once the restore has completed. Some new devices such as iPHONE 6/6S might not show this. You can test with a GSM Sim card (to verify you get signal)
iPhone No Service After Factory Unlock Troubleshooting Guide
If you get No Service on iPhone after factory unlocking you can fix it here. I used info here from different forums, websites and from my own experience and notes from our clients.
There is a part of our customers who are facing No Service problem on their iPhone, especially 3GS owners with iPad Baseband or after using Ultrasn0w unlock. Also there can be on iPhone No Service after restore or update, activation or deactivation with Redsn0w or SAM tool, even after jailbreak.
As to activation and activation you can read separate guide on how to fix activation problems on iPhone after factory unlock.
The problem is not in unlocking. In other words it is better that your iPhone shows No Service than Invalid Sim card or Sim card is not supported.
If iPhone is still locked to AT&T it will never accept other Sim. If you see No Service that means that iPhone accepted the Sim and there are can be tons of other reasons but not in unlocking and here I’ll try to describe most of them.
Most Common iPhone No Service Errors and How To Fix Them
1. The easiest method, and I can confirm that it works in most cases, to reset network settings:
- Insert unsupported Sim card, open Settings on iPhone, go to General -> Reset -> Reset Network Settings.
- Also some say you can try to Erase All Content and Settings but before it do a backup and I heard that it could harm your device.
2. In Setting you will see AirPlane mode which you can also use to fix No Service on iPhone as well:
- Insert Sim card and turn on/off Airplane mode several time while it will pick the signal.
3. Also while your iPhone is on, pop the Sim card out and turn off the power. Insert Sim card and turn iPhone On. Or, turn iPhone on, pop up the Sim card, turn iPhone on and insert Sim card. It worked for many.
4. Go to Settings – General – Cellular/Network and turn on Cellular Data, Enable 3G, Data Roaming and wait for the signal. If they already on – turn it off and wait for the signal.
Note: Some say that you need just reboot iPhone holding two buttons and you will get service.
5. No Service iPhone problem can be after activating and deactivating iPhone using just app as SAMPrefs (SAM unlock tool) or Redsn0w. In this case follow steps in method 6.
6. If methods above don’t work to fix No Service on iPhone, you can try the third method which is the best because it works in 90% cases:
1). Insert non-AT&T Sim card in iPhone and connect it to iTunes using USB.
2). When iTunes detects your device perform a backup and after backup just click Restore.
Note: First try just Restore, without holding Shift/Option. Also you can try to restore putting iPhone first into DFU mode.
3). Wait till the program finish restore and you will see two options in iTunes:
- Restore from a backup;
- Set up iPhone as a new phone.
so choose Set up as a new.
4). After installing iPhone as a new you will need to pass activation steps, so do it with non-AT&T Sim card inserted and wait for the Signal.
If nothing, read and perform methods (1,2,3,4) described above.
7. iPad baseband. There are many iPhones 3GS still running iPad baseband (06.15.00) which you or previous user installed on iPhone for Ultrasn0w unlock. That could be the reason of No Service as well.
First check the baseband of your iPhone: Settings – General – About- Modem Firmware and if you see 06.15.00 – this is iPad baseband and you need to downgrade it. You need redsn0w tool for this. Do steps below:
- Download Redsn0w (blog.iphone-dev.org) and run it as Administrator if on Windows.
- Use Redsn0w to enter DFU mode: in redsn0w go to Extras – Just Boot and follow on screen instructions to put the device into DFU mode.
- When your device will successfully enter DFU launch iTunes and restore iPhone in iTunes.
- Enter DFU again.
- Now download the latest iOS version (getios.com).
- In redsn0w go to Extras – Select IPSW and choose the iOS file you downloaded.
- Go back to the main window of redsn0w and click Jailbreak.
- Choose Downgrade from iPad baseband and uncheck Install Cydia and click Next.
That’s it. After the process you will have service and can make calls.
8. Very often when you try to cut the Sim card yourself many do it wrong and iPhone can’t detect the Sim. You better order the Sim of the carrier you want to use on iPhone.
9. Sometimes there is really no service of the carrier you want to use in the area you are. There can be just no coverage. Or the Sim you try to use is not active anymore. In these case you need to contact the carrier.
10. Other reason of No Service on factory unlocked iPhone is the antenna of your device. Yes, it could also be a hardware issue and your iPhone has a bad antenna and it can’t catch the signal. In this case just contact or go to the Apple Store and ask them to check it for you. If it would be antenna they would give you the new iPhone.
That’s it. All this info was found on different forums, blogs and from the own experience of our clients. Just try every of them and read every no service fix very carefully. Also you can always contact Apple care or the carrier of the Sim card you need to use.
And remember, if iPhone got No Service issue it doesn’t mean that it is not unlocked. If device would still be locked it never accept and activate iPhone with other Sim card.

Make sure the Iphone is updated to the current 6.1.4 or latest version for your model
Make sure ITUNES is updated to the 11.0.4 or current version.
Also try doing this process again on another computer. Sometimes this helps the issue too. Also Fly mode on/off, remove/insert SIM, plug/unplug from computer, connect/disconnect iTunes
If the phone is reported STOLEN/LOST it will not work on USA GSM. It will ONLY work overseas.
Also if the phone is NOT ACTIVATED, it will not work. You will need to activate it by using an ACTIVE AT&T USA sim card through Itunes.
The phone will not work on Sprint/Verizon/Net10
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.
Frequently ASKED QUESTIONS?
1. Can i update to IOS 7? YES you can. It does not affect anything. Please make sure your phone is the most updated verision when restoring
2. Will my phone relock ever? No, this is a permanent process.
3. Can you unlock the IPHONE 5 yet? YES WE CAN.
4. Do you unlock any other providers besides AT&T USA, Telus Canada? No we just unlock these for Retail only.
5. Does Itunes Version matter? Make sure your ITUNES is updated to the MOST current version.
6. How can I tell my iphone is unlocked for sure? Best way is by putting in a GSM (NON supported 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.
7. How do i set up MMS? http://www.unlockit.co.nz/mobilesettings/
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 billing zip code & last 4 of social. Please make sure you DONT confuse UNLOCKING with Activating it. They are two different things.
I received the message “activated” or “unlocked” but when I plug it into iTunes, nothing happens.
– Try connecting to iTunes, perform a back up then restore.
Phone is Jailbroken and will not allow me to do a restore
– You must put your iPhone into whats call “DFU mode”.
– Open iTunes and connect the iPhone to your PC/Mac.
– Press and hold the Home button and the Sleep/Wake button at the same time.
– After exactly 10 seconds release the Sleep/Wake button. Continue holding the home button until you iTunes pops up a message telling you that it has detected an iPhone in recovery mode. Now you can do a restore on your iPhone.
* Note: It may take a few attempts to get your iPhone into DFU mode. Generally, I hold down both buttons then release the Home button just before I think the Apple logo would appear. If you are still holding both buttons down and you see the Apple logo you are holding them down for too long!
