  • Turn off your iPhone and when it is completely off, hold the side button until an Apple logo appears on the screen.
  • An alternate method is to use the Wake/Sleep button to shut down your iPhone. You will need to press and hold that button continuously until you see a red slider and then use it to turn off the device. Once it is off, you can turn it on normally.


You can also try the force restart method if the normal restart doesn't work. Follow these steps:

#4 Check SIM Status

If none of the above mentioned methods work, then you should check your SIM/carrier status. You will surely get the activation error if you are trying to activate your locked iPhone via a different carrier. If that's the problem, then it is recommended that you call your carrier and ask them to activate both your iPhone as well as your SIM card. They will either guide you through the iPhone activation process or provide service to activate your iPhone themselves. Don't attempt to activate an iPhone via different carrier than what it was at the time of the purchase.

#5 Try an Alternate Wi-Fi/Network

Your Wi-Fi/network may be the cause behind the iPhone activation error. It might be because gs.apple.com is blocked on some ports on your network. It is recommended that you try an alternate Wi-Fi network to see if the problem persists. It could be the case that Apple's servers are blocked on a specific network, that's why trying a different connection is worth a try.

#6 Activate Via iTunes

You can also activate your iPhone via iTunes. The process is a bit tricky but is a good alternative if you cannot activate the device in any other way.

Step 1. First, make sure that you have the latest version of iTunes installed. If it's not, then update it via the official website.

Step 2. Now turn off your iPhone and connect it to your computer via lightning cable.

Step 3. Once connected, turn the iPhone on. iTunes will automatically open once you turn your iPhone on. If it's not, then manually launch iTunes from your desktop.

Step 4. Now iTunes will automatically ask you to activate your iPhone upon launch.


Step 5. If iTunes doesn't ask you to activate your iPhone automatically, then use the left pane of the iTunes to select your device and choose the Activate your iPhone option manually.
