FMX Android - connect service

[danten]

Hello,
how to connect to the data mobile network.
Wifi connection is simple and I found help.

Delphi-Quellcode:

procedure TfrmMain.ConnectWifi;
var
  WiFIServiceNative: JWifiManager;
begin
  WiFIServiceNative := TJWifiManager.Wrap(TAndroidHelper.Context.getSystemService(TJContext.JavaClass.WIFI_SERVICE));
  if WiFIServiceNative.getWifiState < 2 then
  begin
    if WiFIServiceNative.setWifiEnabled(true) then
    begin
      WebNavi; // procedure webbrowser navigate
    end;
  end;
end;

procedure TfrmMain.ConnectDataMobile;
begin
  DataServiceNative := ?????
  ?????????????????
end;

Thank you
