If you can't activate your iPhone - Apple Support
See the above...
Try this it's from the above...
Make sure that you have the latest version of macOS or the latest version of iTunes.
Check that your computer has an Internet connection.
With the cable that came with your iPhone, connect your iPhone to your computer. Locate your device on your computer.
Wait while your computer detects and activates your iPhone:
If you see an alert that shows "Set up as New" or "Restore from Backup," it means your iPhone is activated.
If that does not work you will have to restore your phone...
