How can I check which type of cellular connection (EDGE/3G/LTE) is used at the moment? I only know how to check if device is on cellular connection or WLAN, but I need specific type of cellular connection. Thank you!

NetworkInformation should be available for Windows 10 (https://msdn.microsoft.com/en-us/library/windows.networking.connectivity.networkinformation.getinternetconnectionprofile.aspx?cs-save-lang=1&cs-lang=csharp#code-snippet-2).
You have to adjust this code for your needs:
/// <summary>
/// ("Connection Type", `0`-`3`): `0` - cellular, `1` - wifi / ethernet, `2` - inne;
/// </summary>
/// <returns></returns>
public byte GetConnectionGeneration()
{
try
{
ConnectionProfile profile = NetworkInformation.GetInternetConnectionProfile();
if (profile.IsWwanConnectionProfile)
{
WwanDataClass connectionClass = profile.WwanConnectionProfileDetails.GetCurrentDataClass();
switch (connectionClass)
{
//2G-equivalent
case WwanDataClass.Edge:
case WwanDataClass.Gprs:
//3G-equivalent
case WwanDataClass.Cdma1xEvdo:
case WwanDataClass.Cdma1xEvdoRevA:
case WwanDataClass.Cdma1xEvdoRevB:
case WwanDataClass.Cdma1xEvdv:
case WwanDataClass.Cdma1xRtt:
case WwanDataClass.Cdma3xRtt:
case WwanDataClass.CdmaUmb:
case WwanDataClass.Umts:
case WwanDataClass.Hsdpa:
case WwanDataClass.Hsupa:
//4G-equivalent
case WwanDataClass.LteAdvanced:
return 0;
//not connected
case WwanDataClass.None:
return 2;
//unknown
case WwanDataClass.Custom:
default:
return 2;
}
}
else if (profile.IsWlanConnectionProfile)
{
return 1;
}
return 2;
}
catch (Exception)
{
return 2; //as default
}
}
