However, when on the mobile network like 3G connection, is it still possible to obtain

Answer 1

try something like this

String ipAddress = null;
    try {
        for (Enumeration<NetworkInterface> en = NetworkInterface.getNetworkInterfaces(); en.hasMoreElements();) {
            NetworkInterface intf = en.nextElement();
            for (Enumeration<InetAddress> enumIpAddr = intf.getInetAddresses(); enumIpAddr.hasMoreElements();) {
                InetAddress inetAddress = enumIpAddr.nextElement();
                if (!inetAddress.isLoopbackAddress()) {
                    ipAddress = inetAddress.getHostAddress().toString();
                }
            }
        }
    } catch (SocketException ex) {}

Answer 2

the mobile device does not have an ip when browsing over 3G connection, You will get the ISP ip on the server side code. I recommend you replace the ip with the unique id, device type and coordinates if possible.
