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?
You should be able to go to settings, find your settings for you sim (APN) settings and from there be able to copy these settings to your new phone.

I am assuming your current device is an android device. On my phone (OPO5T) I can simply go to settings->Wi-Fi &amp; internet->SIM &amp; network->(My sim card)->Access Point Names.
