new phone can't establish a connection to the server

[DizzyMe63]

First Boost Mobile told me that my Boost Mobile phone wasn't a Boost Mobile phone. Then I got it activated online but when I put my Google address in it read that it "can't establish a connection to the server". Boost Mobile representative told me to shut both phones off (the one I was switching for the new one)and told me to turn wifi off and mobile data on, then to pull up the dial pad and enter ##72786#. When I turned the phone on it goes straight to Google sign in where I got this message. I can't even get to the settings to turn wifi off and mobile data on. I can't even get to the dial pad! It just told me to call Customer Care!
