Recently, we received some e-mails from our visitors with an error code new to us. Our visitors also provided us with screenshots of their problem, which shows the following message to their screen: “Unauthorized Device – This iPhone cannot be activated for service“.
Below this message, it informs you to either contact your Carrier or AppleCare to solve this issue, but do not expect any real help. They will tell you that this iPhone is not authorized to their network (If you contact the carrier) or that you should contact your iPhone’s carrier (If you contact AppleCare).
After many hours of research, we were able to find a solution, which will unlock your iPhone and remove the “Unauthorized Device – This iPhone cannot be activated for service” error message from your screen.
What “Unauthorized Device – This iPhone cannot be activated for service” message means?
It is not very clear of the actual meaning of that message, but after some GSX checks (Information that we got from Apple’s GSX servers), we figure out that an iPhone that have the Unauthorized Device message, is blacklisted and locked.
It is not showing from which mobile network it is locked and blacklisted, which most likely means that this iPhone is blacklisted by Apple.
Our first though was that if this iPhone is blacklisted by Apple, then it will not work with any networks (Worldwide Blacklisted), but this is not true.
You can get an idea in which country it was blacklisted, by the Purchased In value. Most likely, this iPhone (after the unlock) will not work there.
How to remove the “Unauthorized Device – This iPhone cannot be activated for service” message?
The only way to remove this message from your iPhone, is to unlock it (Network unlock). Since it is not clear from which network it is locked, it is impossible to pick the right iPhone unlock service (The Official IMEI Method, requires the Network that locks your iPhone in order to successully unlock it).
The Worldwide iPhone Unlock service does not require any information about your iPhone, only the IMEI number.
Before ordering a Worldwide iPhone Unlock service, you need to make a GSX check to your iPhone, to get an idea of where your iPhone cannot be used (Since it is blacklisted).
Order a Worldwide iPhone Unlock service to remove the Unauthorized Device message
The Worldwide service will unlock your iPhone permanently, will allow you to use iTunes normally and also you will be able to upgrade your iOS version without relocking your iPhone.
