Reasons Why iPhone Fails Activation After iOS 11/iOS 11.3/iOS 12 Update
- Busy Apple Server: Imagine the amount of Apple devices in the world, and the fact that a significant proportion is always trying to contact the server. Despite Apple’s resources, it’s not uncommon for glitches to be borne out of high traffic, though very rare. Therefore, the activation server might just be temporarily unavailable the moment you were trying to activate your device.
- iPhone not recognized: In this case, there’s a local error preventing your device from contacting the activation server. It could be wrong details, issues from your carrier or Wi-Fi couldn’t connect.
- iTunes unable to verify your device: Another reason might be that iTunes cannot verify your device because of wrong login details.
Things To Do If You Cannot Activate iPhone 7 After Installing iOS 11/11.3/12
As reported by most users, the activation issues arise immediately after the download has taken place and they can’t sign in. Even Apple concurs that this issue is peculiar to older devices. The following tips will help you reactivate your account.
This will work only when the problem is an error from Apple’s activation server. If this were the case, chances are you’ll be able to activate your account once you wait it out a few minutes. If your iPhone activation error doesn’t change after this, it’s time to turn your attention somewhere else.
2 Restart Your Device
A hard reset is perhaps an iPhone owner’s go-to solution for most iPhone problems; and why not, when it usually fixes most errors. Just hold down the “Home” and the “Sleep/Wake” buttons together for about 10 seconds and wait for the device to reboot. Try activating the device again. If it doesn’t work, move to the next step.
3 Lock/Unlock SIM Status
Another problem worth examining is your SIM card/carrier. If, your phone is recently purchased from your carrier, it will not get activated until it is unlocked. In some cases, what is required is to contact your carrier and ask them to unlock your iPhone and SIM card. If your iPhone and SIM card has been unlocked before, then you can attempt to bring out your SIM from the iPhone and reinserting. Try activating your iPhone again.
4Wi-Fi/ Network Issues
Another problem that could be preventing your iPhone from being activated is your WI-FI or network. Perhaps the gs.apple.com is blocked on some ports. Try connecting to another Wi-Fi to see if the problem is peculiar to the former WI-FI/network.

This is the last resort when you’ve tried all else. It’s very rare to try all the above and still come up short. In our experience, iPhones that have been jailbroken or tampered with in other ways usually have the activation problems.
