Introduction
In this article I'll explain the simplest to check the cellular operator name and data roaming status in Windows Phone. This is a very necessary and required feature for all apps that use an internet connection and operator specific services. For example if you you want to request something from the internet or send something to the server that may require a data connection then you need to alert the user about roaming to avoid extra charges while in roaming. So let's start.
Device Network Information
This class contains network information for a specific Windows Phone device. Using of this class we can check various device network parameters, like it's availability, roaming, network change, WiFi status and so on. To use this class you need to include the namespace "Microsoft.Phone.Net.NetworkInformation".
CellularMobileOperator
This property contains the name of the operator. It returns a string of operator name.
IsCellularDataRoamingEnabled
This property contains the status of cellular data roaming availability. If roaming data is allowed then it will return true else it'll return false.
Demo
To run this project create new project and add the following code to an XAML file.

{
romSts.Text = "Roaming Data enabled.";
}
else
{
romSts.Text = "Roaming Data not enabled.";
}
}
}
}
DeviceNetworkInformation.IsCellularDataRoamingEnabled checks for cellular data roaming availability.
DeviceNetworkInformation.CellularMobileOperator gets the mobile operator name.
