"No Service" error in a Factory Unlocked iPhone.

I'm using iPhone 3GS iOS 6.1 with 05.13.04 Baseband. My phone is Factory Unlocked with Turkey / Avea. But I get "No Service" error. Why does this happen and how do I fix it? I'm already using an Avea SIM Card.

Contact Avea about this. Here's how:

No Service with factory unlocked iPhone 4S

I bought a factory unlocked iPhone 4S in Canada – it worked perfectly with the different Canadian carriers (Rogers and Telus).
I moved to Denmark to study and have recieved a SIM card from Oister (uses 3's network).
When I put the SIM card in it recognizes the SIM card and asks for a PIN code, which I enter. After that I get a carrier update. However after that it sits on Searching... for a bit before going to No Service. A look in the "About" section shows "3" as the operator however under Network it says "SIM not provisioned".
I've tried to do a simple restore and update to 6.1.3 with no success. I've even done a DFU restore with no success.
The strange thing is that I'm not getting any "Your iPhone has been unlocked screen" or anything like that when using iTunes. For example, I restore my iPhone, then the activation screen comes on the iPhone, I go through the whole process and get to the homescreen after which iTunes asks me if I want to restore my iPhone from an old backup. No errors or messages telling me my phone is unlocked/not unlocked.
I know the phone is unlocked for sure, I even gave Apple a call and they checked and their systems indicate that my phone is unlocked.
Any ideas?

Iit sounds like your account is not properly provisioned by your carrier. Contact them and have them check the provisioning on the account.

I had already update mi new factory unlocked iPhone 4S to iOS 5.1.1 and I still having problems with "invalid sim". I'm from Argentina and here we don't have official service. PLEASE HELP ME, WHAT CAN I DO??? In Argentina is too expensive an iPhone 4S.

Was it purchased from an official Apple Store, not a reseller? Only Apple Stores sell official factory unlocked phones. The others sell hacked to unlock phones, and the unlocking is unstable.
Try these steps, as needed:
1. Reset phone - press both home and on/off buttons for at least 10 seconds until the Apple logo appears.
2. Settings > General > Reset > Reset Network Settings.
3. Replace SIM card (and reset network settings again)
4. Restore Phone in iTunes using a backup
5. Restore in iTunes as new, without using a backup

Can not update 5.1.1 to 6.0 on factory unlocked iPhone 4S - An unknown error occurred (-1) (21)

HI all,
for the first time, one of my Apple products is making me mad.
1.) I have an factory unlocked iPhone 4S running 5.1.1
2.) When I try to update, it (MacBook Pro running 10.8.1) extracts the software and then after a few seconds it shows me (An unknown error occurred (-1))
3.) When I put the phone in DFU Mode and try to update it shows me (An unkown error occurred (21)) - The iPhone freezes at the Apple Logo
I have downloaded the IPSW again (Yes I am sure I have the one for iPhone 4S), have downloaded and installed iTunes 10.7. Further I have installed iTunes fresh on a another Laptop (iTunes 10.7 on Windows 7) - Same behavior there.
The funny thing is, when I restore the iPhone to 5.1.1 it restores it without any problem. I have also tried to first make a restore on 5.1.1 and directly on 6.0. Same problem.
PLEASE HELP ME!
Cheers
Peter

You might try using RedsNow to put it in DFU mode.

I wouldn't even take a chance at getting it serviced in the US.
If you did happen to find a store willing to service it under warranty, they would most likely replace the device. That means you would end up with a US iPhone locked to AT&T.
Do you really want to run that risk?
Take the device to the country of origin and have it serviced there.

How do I get a factory unlocked iPhone 3GS out of (connect to iTunes) mode?

How do I get a factory unlocked iPhone 3GS out of recovery (connect to itunes) mode?
Once the iPhone 3GS is in DFU mode and plugged into iTunes, the restore and update process begins. The restores process are as followed:
Extracting software > Preparing iPhone for restore (blank screen) > Preparing iPhone software for restore > Restoring iPhone software > Verifying iPhone restore > Restoring iPhone firmware > The iPhone cannot be restored. An unknown error occurred (1).
I clicked on the more information tab and was taken to a website with some troubleshooting. I did what they suggested (based on the error #) and still no luck. I’ve tried to restore and update about 10 times now but the same message keeps coming up at the end. What should I do now?
P.S: I have the latest version of iTunes (11), my windows is up to date etc ...

Can't activate a Factory Unlocked iPhone 4s.

I NEED HELP PLEASE!!!!
I PURCHASED A FACTORY UNLOCKED IPHONE 4S WITHIN THE US AND PAID $706 FOR IT AND WHEN I SHIPPED IT OUT INTERNATIONALLY TO MY FIANCE BACK AT HOME, SHE CONNECTED THE PHONE TO ITUNES AND SHE IS UNABLE TO ACTIVATE IT. IT DOES NOT GIVE THE MESSAGE "YOUR PHONE HAS BEEN SUCCESSFULLY UNLOCKED" AND THEREFORE IT SAYS NO SERVICE ON THE PHONE. THE OPERATING SYSTEM ON THE PHONE IS THE iOS 5.0.1. FURTHERMORE, I GOT IN CONTACT WITH A SENIOR ADVISOR FROM APPLE AND HE TOLD US TO RESTORE THE PHONE AND THAT MIGHT HELP. SHE TRIED RESTORING THE PHONE AND NOW WE CAME ACROSS ANOTHER PROBLEM WHICH GIVES HER THE ERROR 1630. PLEASE CAN ANYBODY HELP???

First, STOP SHOUTING.
Second, you did NOT purchase an unlocked 4S in the US. The brick and mortal Apple stores do not yet have them in stock. They can only be ordered online and have not yet been readied for delivery.
What you likely purchased was a contract-free iPhone, which is NOT unlocked. Your fiancee will NOT be able to activate that phone.

I am afraid it's late to return back,looks like i m stuck with it or someone hopefully will find solution for it

T-Mobile SIM card won't work with my replacement factory unlocked iPhone 5

On Saturday, my rear camera on my factory unlocked iPhone 5 stopped focusing. I took it in to my nearest Apple store and they replaced it. Problem is, now I can't get my T-Mobile SIM card to work with the replacement phone. The guys at the genius bar sent me to T-Mobile to see if a new SIM card would fix the problem, but I'm still getting an "Unsupported SIM" error when I try to activate the phone. Any insights?

Do you have information about the model no. of original purchase that is printed on the back cover ?
What is model no. of the replacement iPhone 5 ?
If T-mobile SIM worked on the original purchase and does not work on the replacement iPhone 5, they gave you a wrong model.

EDIT 2: It cannot be restored via iTunes 'cause I get a screen message saying that there's no SIM card in the iPhone I'm attempting to activate. The friend who sold me the phone showed me a method for restoring it on the phone itself, without having to send the command through iTunes (connect the phone to computer, turn it off, hold both Home and Power buttons until the Apple logo disappears, release the Power button without releasing Home button, iTunes shows a message about an iPhone in restoring mode, restore, etc.). Thing is, I tried this two or three times on the iPhone 5 but the device still doesn't recognize the stupid SIM…
Please, help

Factory unlocked iphone 5 turns out to be locked

My aunt bought a factory unlocked iPhone 5 from London apple store at full price 530pounds. When I insert the nano sim in it, it says no service. So I went to IMEI.info and typed its imei. The status showed that my iphone is locked. What should I do now?

My understanding is that UK carriers will only authorize unlocking if you are a current customer.
Unlocking is accomplished by them submitting a request to Apple, and once processed, you restore the phone using iTunes on your computer.
You'll have to contact the carrier it's locked to to find out their specific requirements. There may be an additional fee.
IF the receipt from Apple says that it was sold as unlocked, Apple Care should be able to resolve the issue for you without a charge.

How to activate factory unlocked iphone 3gs with os 4.0

i have bought a factory unlocked iphone 3gs loaded with latest os 4.0 in usa for $850 , but i am unable to activate it over itunes.
I want to activate it without at&t sim as its factory unloacked.
Can anybody give me the process or any reference links on how to activate it.
Thanks in advance,
Pavan Raj.

If the iPhone had the 4.0 Beta loaded on it, the iPhone needs to be registered with a developer for the iPhone to even function. If it's not registered and the beta is installed then it is a brick. Regardless of if it is registered or not, as Tamara said the iPhone 4.0 Beta has no support. The Beta is a beta and is for developers who are developing apps. That way they can release apps as soon as the OS 4.0 is released sometime this summer. You should get an error message saying something along the lines of this phone is not registered with a developer, if the iPhone is not registered.

If it is unlocked by the carrier then you just need to plug it into iTunes with a SIM card from a compatible carrier. If you get a message saying that the SIM is not from an authorized carrier, well then the iPhone is not unlocked, sorry.
If the iPhone is not unlocked you are really out of luck. While there are ways to hack an iPhone to unlock it, there are no methods for the 4.0 Beta to unlock the iPhone, and even if there is a way to hack it to unlock the iPhone 3GS on the 4.0 OS, it won't come for a long time.

Okay i just recently asked a question.about my factory unlocked iphone 3gs asking how to activate it but..

i probably shouldnt say this but,okay i just recently asked a question.about my factory unlocked iphone 3gs asking how to activate it. so i got too excited of aving it and couldnt wait for my tmobile sim card to come one more day. so i "hactivated" it (i know this voids all warrenty) and i jailbroke it just so i could use it as an ipod.it worked and i was syched.
BUTTT.... it asked me if i wanted to update the software to 5.1 and i was like " oh yes id love to" and it started downloading it and it was inrecovery mode the whole time .
when the download finished. i hit restore so i can put the software on the phone but the itunes had an error and the phone went glitchy and it does a rebooting loop. it shows the apple symbol with the slash through it for about 5 seconds and shuts off for a little bit (about another 5 seconds) and it starts up then loops the process. ive managed to turn the phone off but if i start it up it loops...what should i do? any help :/
Also it does not show up in my itunes because it is turning off to fast to detect.

Discussion of hacked phones is prohibited on these forums. Sorry, you'll need to go elsewhere to get support for a j'broke iPhone.
