Received unlock instructions but no unlock code

Greetings @Winter32708!

I am so sorry to hear after receiving your approval for your device unlock, it didn’t come with the code. Don’t worry though; you have come to the right place, and I would be more than happy to assist!

The great thing about unlocking an iPhone, is it doesn’t require an unlock code such as an Android would. There are two different ways to unlock an iPhone; either by using a new SIM Card, or by completing a Backup & Restore on the device.

If you have a SIM from your new carrier, please follow the steps below:

1. Remove your SIM card and insert the new one. 
2. Set up your iPhone again.

If the above does not work, or you do not have a new SIM available, don’t worry you can still unlock your device. Just follow the steps below to unlock it:

1. Back up your iPhone.
2. After you make a backup, erase your iPhone.
3. Restore your iPhone from the backup you just made.

I hope this information helps! If you have any other questions, feel free to visit this thead again. Have a splendid rest of your week!

Hello @Winter32708,

Thank you for letting me know what steps you have already tried.  If you could Please try these steps, I believe we can get the phone unlocked.

• Plug the phone into computer and open iTunes and preform a backup.  The steps can be found on Apple’s support article towards the bottom.

• Erase all content off the phone by going to Settings>General>Reset> Erase All Content and Settings

• Restore the iPhone from iTunes by following Apple’s support article.

• Once this has been completed you will get a screen which says “Congratulations your phone is unlocked” Once you see that screen the other SIM will work.

I hope this helps! Have an excellent rest of your day!

I followed your instructions in the email but I got the following failed messages:

- From Iphone : "SIM Not Supported ........."

- From PC's ITunes: "The SIM card inserted in this iPhone does not appear to be supported.....or request that this iPhone be unlocked by your carrier...."

Below are steps I did:

1. Since the phone has no data so I do not need to perform a backup. I erased all old data: Setting>General>Reset>Erase All Content and Settings.

2. Connected IPhone to PC and started Setup the phone and received above messages.

Please let me know if I missed any extra steps and what do I need to do ?

Thank You !!!!!!

@Winter32708 Since the iPhone 4 has an older version of iOS, I'm pretty sure the only unlock instructions that will work is to connect your iPhone to iTunes and either do a backup/restore or reset to factory settings but you need an ATT SIM card in the phone when you do that. The SIM card does not have to be active but it does need to be an ATT sim. Once the phone re-authorizes in iTunes, you then should get the message the phone is unlocked. At that point you can put in a SIM card from another carrier.

@Winter32708 It's been a long time since I unlocked an iPhone 4, I don't remember exactly where in the process that message displayed but it is very possible the unlock completed successfully but no message displayed. Go ahead and try the other carrier SIM card.
