Radio.SetStateAsync(RadioState) Method doesn't work for MobileBroadband RadioKind (VB+Windows10)

Question

I want to control RadioState of Wifi and Mobile(cellular) connection in Windows 10 x64 using custom application written in VB. It works for Wifi radio but doesn't for MobileBroadband.

Actually code does the same job as click on ActionCenter in Windows 10 and press Wifi or Cellular button.

 Private Async Sub TurnMobileOnOff(arg As Integer)
    Dim access = Await Windows.Devices.WiFi.WiFiAdapter.RequestAccessAsync
    Dim radios = Await Windows.Devices.Radios.Radio.GetRadiosAsync
    If access = Windows.Devices.WiFi.WiFiAccessStatus.Allowed Then
        For Each radio In radios
            If radio.Kind = Windows.Devices.Radios.RadioKind.MobileBroadband Then
                If arg = 1 Then
                    Await radio.SetStateAsync(Windows.Devices.Radios.RadioState.On)
                    RichTextBox1.AppendText(vbCrLf & "Mobile connection is turninng on")
                ElseIf arg = 0 Then
                    Await radio.SetStateAsync(Windows.Devices.Radios.RadioState.Off)
                    RichTextBox1.AppendText(vbCrLf & "Mobile connection is turninng off")
                End If
            End If
        Next

    End If
End Sub

There's no error message, just radiostate is unchanged. The same code works for WiFi as expected.
