Answer 1

It seems sending SMS from a BlackBerry is not always that simple. I thought I had it figured out, but it didn't work when the BlackBerry user was on a CDMA network as opposed to GSM, which I was using.

I found the solution here and adapted it to this. Different from that example is also the port number, I use port 5016 as suggested on the Blackberry support forum and the Blackberry knowledge center.

private static byte[] stringToByte(String s)
{
    char[] sa = s.toCharArray();
    byte[] ba = new byte[sa.length];

    for (int i = 0; i < ba.length; i++) {
        ba[i] = (byte) (sa[i] & 0xFF);
    }

    return ba;
}

private static void sendCDMAText(String nr, String message) throws IOException
{
    DatagramConnection conn = (DatagramConnection) Connector.open("sms://+" + nr + ":5016");
    byte[] bytes = stringToByte(message);
    Datagram msg = conn.newDatagram(bytes, bytes.length);
    conn.send(msg);

}

private static void sendSMS(String nr, String message) throws IOException
{
    MessageConnection conn = (MessageConnection) Connector.open("sms://" + nr);
    TextMessage msg = (TextMessage) conn.newMessage(MessageConnection.TEXT_MESSAGE);
    msg.setPayloadText(message);
    conn.send(msg);
}

public static void sendTextMessage(String nr, String message) throws IllegalArgumentException, InterruptedIOException, NullPointerException, SecurityException, IOException
{
    if (RadioInfo.getNetworkType() == RadioInfo.NETWORK_CDMA) {
        sendCDMAText(nr, message);
        return;
    }

    sendSMS(nr, message);
}

To send a text message, you would call it like this:

sendTextMessage("555123123", "The little text message you wanted to send.");

^{(Where 555123123 is a Hollywood phone number.)}
