I bought an iPhone 6 Plus on eBay and everything was fine but after it did an update now it doesn't let me to activate it. It asks me to enter my Apple ID and Password and after I put my info it tells me to hit "Next" and when I do it says "Activating iPhone" later "Updating iCloud Settings" and then "Welcome to iPhone" and but once I hit "Get Started" it shows an error on the screen saying "Activation Required-Dismiss" and it takes me back to the "Enter your Apple ID and Password" Screen. I have tried everything, I tried through iTunes and nothing, I even removed it from my iCloud-Find My Phone section and still nothing. I even tried a restore through iTunes and no luck. I called my carrier and they don't know what's going on. They told me it could be the SIM card but I tried another one and still nothing. And this ONLY happens when I insert my SIM card...if I remove it then I can use the phone with no problem and use my Wifi to download apps and stuff. Please Heeelp!
