iPhone 6s+ wont Activate
My iPhone 6s+ won't activate, with the sim removed everything is fine, when I insert the new sim it pops up that it successfully updated, when I go through the steps get either Apple activation servers could not be reached or I get a white screen with the Itunes logo, Im at a loss at what I can do. I have tried everything (restore the phone, reset the phone, contacting my carrier, contacting apple)
iPhone 6s Plus, iOS 11.2, Rose Gold 64GB
