please refrain from providing personal data, this forum is publically accessible to anyone and you're not addressing Apple or its employees here, only fellow product users.

Regarding your issue: what is it exactly you see? Any error messages?

If you are getting a message that the activation server is unavailable, either you don't have a SIM in the phone, or the phone was hacked to unlock it.

In the first case, put a SIM in it.

In the second, contact the carrier it's locked to and see if they will unlock it.
