iPhone 7 activation issue
I bought an iPhone 7 online a couple of weeks ago.
Checked before I bought it, it has no iCloud lock, no carrier lock, no sim lock nothing.
Checked on Apple support page, it has a valid purchase date, valid warranty, valid tech support.
Everything looked ok but when I got the phone did an iOS restore and now it won't activate. Was working fine before restoring it.
Run an IMEI report and the only thing that I noticed not being right is under "Next Tether Activation Policy Description" it says "Chimaera Device Policy Applied".
Apple support was't much help figuring out what's wrong with it.
Anyone knows what this means and most importantly how can I fix it?
iPhone 7, iOS 10.2.1
