    1) Well, There is no Method for the Sms Connection which you could retrieve - isAlive().
    A solution in which you could do is Wrapping your SMS code over Thread or Timer+Tasker(for Scheduling your Sending.

    This is only an example. for sending text message over sms
    import java.io.IOException;
    import javax.microedition.io.Connector;
    import javax.wireless.messaging.MessageConnection;
    import javax.wireless.messaging.TextMessage;
    /** Sends an SMS message */
    public class SMSender implements Runnable {
      private String smsReceiverPort;
      private String message;
      private String phoneNumber;
      public SMSender(String smsReceiverPort) {
        this.smsReceiverPort = smsReceiverPort;
      public void run() {
        StringBuffer addr = new StringBuffer(20);
        // String address = "sms://+8613641301055";
        String address = addr.toString();
        MessageConnection smsconn = null;
        try {
          // Open the message connection.
          smsconn = (MessageConnection) Connector.open(address);
          // Create the message.
          TextMessage txtmessage = (TextMessage) smsconn
          txtmessage.setAddress(address);// !!
        } catch (Exception e) {
        if (smsconn != null) {
          try {
          } catch (IOException ioe) {
      public void send(String message, String phoneNumber) {
        this.message = message;
        this.phoneNumber = phoneNumber;
        Thread t = new Thread(this);
    2) impossible at the moment.

    Hello prashantpersistent,

    2.is there any solution to check whether device battery power is low ?
    Currently this is possible only with S60 3rd Edition, Feature Pack 2 devices by using this system property string:


    Using System.getProperty("com.nokia.mid.batterylevel") returns the battery charge level of device. The property value is the actual battery level in percentage.

    Source (under 'S60 3rd Edition, FP2 system properties'): http://wiki.forum.nokia.com/index.ph...tem_properties
