Could not activate iPhone server cant be reached after factory reset

My 1st time of even owning an iphone and i only have it as i was given an iphone 5c and i reset it thinking i`ll start from scratch and i have exact same problem!This is why i have always said i don`t like them because of the complications!It`s just another way for apple to make money in my opinion and in the meantime i`m without a phone!Thanks apple!

"Connect your iPhone to iTunes with an active Internet connection. See if iTunes will activate the phone.

You may need to restore to 11.2.1 via iTunes for this to work. Do a restore, not an Update.

Alternatively, I think the question that is avoided is ""Who is your carrier?"" Some MVNOs need to be called, contacted via live chat, or emailed and need to be live on hand while the activation occurs."
