I keep trying to activate iPhone did everything from hard reset to plug into iTunes over and over… The iPhone take you through all the activation steps to set up to the welcome to iPhone. I press get started and iPhone then goes inside the iPhone for like one second then black out goes back to Hello screen and then Activation Required pops on screen.. On iTunes it says iPhone can’t be activated try again later.. Has anyone ever incountered this problem before?? Someone please help…

I’m surprised nobody ask this but do you actually see an IMEI number displayed when you tap on the blue circle i icon on the setup lock screen? Sounds like the baseband chip needs to either be replaced or reballed.

Take out any sim card in it. Connect it thru Itunes or 3 u tool and just flash it.

What is your iOS version. I heard of that if iPhone 5s on iOS 11+, it could not be activate. You can aslo try to activate your iPhone with 3uTools.
