Here are the reasons you might get the message that the Activation Server is unavailable:

It really is unavailable. Rare, but it happens. You can check its status here: https://www.apple.com/support/systemstatus/
Your version of iTunes is out of date. You need version 12.6.3 minimum.
The phone does not have a valid SIM installed.
Your antivirus or firewall is blocking access to gs.apple.com. Try temporarily disabling it.
Your router's firewall is blocking access to gs.apple.com or to a port that it requires (443).
Your phone is jailbroken, or it was at some time in the past.
Your computer was used to hack or jailbreak some iOS device in the past (not necessarily the device with the current problem), and its network database was corrupted. Hacking includes using some questionable apps such as recboot, reiboot, Tinyumbrella, redsn0w, etc. If this is a possibility inspect your computer's hosts file. If there are any lines in the file that reference gs.apple.com that is the explanation. You will need to rebuild the hosts file.
Your phone has a hardware problem. Take it to an Apple store for diagnosis.

i dont have any problem with ios 11. i have been succesfully upgrading all user phone from ios 9.x.x to 11.x.x or from 10.x.x to 11.x.x. i dont have any problem with device from 5s till 8+. but i have problem with my ipad mini that has been bypassed activation before with changed and modified the hardware . so assumed that your problem is because your iphone is not original any more , may be it has been modified and refurbished from ilegal company

Where did you go to get the Factory Unlock?

I didn't understand any of that. The only place to get legitimate factory unlocked iPhones is directly from Apple. If you did not get it directly from Apple and it is unlocked it must have been hacked to unlock it. That process breaks the activation capability.
