Can't activate iPhone 6s
Hello,
I just bought a new iPhone 6s, I connected it to iTunes, set fingerprint and password and even updated iOS, but at the next step it can't connect with Apple ID server and doesn't let me proceed. I double checked my Apple ID on my Mac and it is working properly. I spent the last 3 hours trying to find a solution, but nothing...is there anyone who can help me with this problem?
Thank you very much.
iPhone 6s, iOS 9.2
