How to Fix iPhone Activation Errors after Updating to iOS 9.3

I selected to update to iOS 9.3. After it installed, I cannot get past the Activate iPhone. I am prompted one Apple ID in parenthesis but that is not my Apple ID. When I enter my correct Apple ID and password, I am told I cannot use that email to unlock the phone.

Are you having trouble in activating your iPhone after iOS update? We have already heared of plenty of iPhone activation issues since iOS 9.3 released.

There are four iPhone activation errors after updating to iOS 9.3 that most users have come across. They are:

  • "Your iPhone could not be activated because Apple's authentication servers simply being overloaded."
  • "The iPhone is not recognized and cannot be activated for service."
  • "iTunes was unable to verify your device."
  • "The SIM card inserted in this iPhone does not appear to be supported"

In some cases, the hint that you see on the Activate iPhone screen might not match your current Apple ID. To make sure that you're entering your Apple ID information correctly and have the latest iTunes version, try the following top ways to solve iOS 9.3 activation errors:

How to Fix iPhone Activation Errors after Updating to iOS 9.3

Solution 1: Wait

The first time you see this error, it's better to wait. Sometimes the servers at Apple are truly busy or buggy which means the activation stuff isn't going through. You should wait for a few minutes before trying again.

I'd suggest you to remove the SIM from the tray and then re-inserting it onto the tray and then trying to go through the activation process again.

Solution 2: Restart

Restarting your iPhone is one of the simplest ways to fix the error. While it doesn't instantly guarantee that your activation will go through smoothly, there's a strong chance of that happening. You know how to restart: Press and hold the power and home buttons for 10 seconds until the Apple logo appears, and then slide it to turn off. And now, reboot your iPhone to try activating it again.

Solution 3: Check WiFi Issues

If the methods above don't work out, then maybe there's an issue with your cellular connection. To rule that out, try connecting to the activation server in a different way. First, find a WiFi hotspot and try the activation process there. If that doesn't work, physically connect the phone to your computer using the USB cord that came with it. Once it's connected, open iTunes. iTunes should detect the new iPhone and attempt to activate it for you on your computer.

Solution 4: Via iCloud

Step 1: Turn off your iPhone or set it offline firstly.

Step 2: Visit and log in with your Apple ID and password.

Step 3: Select "Find My iPhone" and input the password of your Apple ID to confirm , then click on "All Devices" on the top. After that, choose the device which can't be activated and hit "Remove from Account".

Step 4: Turn on your iPhone, and then activate it again.

Solution 5: Talk/Take to Apple Care

If nothing works, maybe it's time to call Apple Care and figure out a solution to tackle iOS 9.3 update issues through the customer support guys.

Note:If you have jailbroken your iPhone previously (or tampered with it, hacked it or modified it in anyway other than permitted by Apple), chances are that is what is causing the activation error. Restoring should mostly set things right but if it doesn't, the jailbreaking/modification might also be a reason.

After these above methods, your iPhone should be activated and will run as normal. If not, you are suggested to contact Apple Support for further assistance. For other iOS 9.3 problems and fixes, view Tenorshare official website for help.
