How can I transfer all carrier settings from an existing phone to a new phone?

I have been provided a device for a telephone carrier that cannot be joined automatically. When the Sim is inserted into another phone, it cannot find/connect to the network. Due to the nature of the network I am on, and given I was supplied the phone from the telephone carrier, I believe its customized in some way. I want to use this network and sim card, but on a better phone (Razer Phone 2). Is there some mechanism I can use to transfer all settings from one phone to the other, including whatever secret settings the carrier may have setup prior to handing out the devices?
