Answers

General questions

How much does it cost to send a short message?

You pay only a standard tariff of your mobile operator per SMS. Some operators offer various SMS packages (from $0.01/SMS) or even unlimited SMS messaging for a certain fee (visit your mobile operator's site for details). And you need to pay for the Headwind SMS messaging software (a one-time fee, see price list for details).

How many SMS a typical modem can send per minute?

The typical sending time is 1 to 5 seconds depending on the GSM network, so the frequency is 12-60 SMS per minute.

Why am I asked to enter a code?

This is the registration code, which is delivered to you after you purchase Headwind SMS software. During a 30-day trial period, you do not need to enter the code; you are able to send SMS from PC via Headwind SMS Suite anyway.

Are you a content provider giving credits for SMS sending through the Internet?

No, we are selling the SMS software working with GSM modem. We have no SMS gateway and we can not give you the account for sending SMS through the Internet.

May I know the price quote for the Headwind SMS Communicator and Headwind GSM Modem Driver?

The prices can be found here: http://www.h-sms.com/purchase.php

I need to know what I will need in order to have this facility available on my website (or if it can be done at all). Can you please let me know if your product (headwind sms) will allow this application.

Headwind GSM Modem Driver has the COM interface for sending SMS. If you are developing a website in ASP and the server runs under Windows OS, then you can use our software to send SMS from an ASP script. There is an example in VB.NET in the distributive. On Windows Apache/PHP server, you can use PHP scripts. To send SMS from the remote hosting, please use SMS source.

We want to send the sms which are saved in dbf file or in text file (different messages for different numbers). Is it possible?

This can be done using SMS sources. Please look the web page for details: http://www.h-sms.com/help/sources.php.

Is it possible to support multiple modems with Headwind GSM Modem Driver? Could one buy additional licenses for this purpose?

Yes, it is possible, but with some limitations. See http://www.h-sms.com/instances.php for details. This is currently the experimental feature, and you do not need additional licenses for this.

Is it possible to hide the sender number or replace it, for example, by the company name?

No, it is not possible. The sender number is not sent through the GSM network, it is setup by the mobile operator.

Technical questions

Which GSM devices are supported?

The software is potentially compatible with all GSM devices supporting GSM 07.05 and GSM 07.07 standards (ETSI GSM phase 2/2+). You can refer to the list of supported devices for details.

Which GSM device is the best one?

In different countries, the list of GSM devices available on a market may vary. Some compatibility issues are listed in the list of supported devices. Please note that the USB cable connection is more reliable than the Bluetooth connection.

Can I use CDMA phone with your software?

No, you can not use it. CDMA standard for sending SMS is completely different from a GSM standard.

You need to open a control panel by double-clicking an application icon and look for the SMS in folders "Outbox", "Sent", "Failed". If the SMS is in "Sent" folder, then it must be sent successfully.

How can I use SMS for the remote management of my computer?

You may set up a command-line handler for incoming SMS. The handler may be written in any programming language, it gets the contents of a message through a command line.

May I setup an autoresponder for incoming SMS?

To make an autoresponder, you must use the COM interface. It is recommended to write an autoresponder in a COM-friendly programming language such as Visual Basic.

Can the application work as Windows service?

Headwind GSM Modem Driver was designed as an application which interacts with the desktop. However, it can be setup as Windows service using Windows 2003 Resource Kit utilities. Here is the installation guide.

How can i get the data from the mysql database to send as an sms? Do you have an example of scripts?

To get the data from the mysql database, you need to setup a command-line SMS source, see http://www.h-sms.com/help/cmdline_source.php. You can request us the example of MySQL VBScript source. Before using the script, you need to install MySQL Connector/ODBC 3.51, and update the settings inside the script.

I would like to know your capabilities in bulk SMS. How do you enable your customers, versus website or versus the software deployed at the customer's environment?

The software uses the GSM modem for sending SMS. Normally, it is deployed at the customers environment. However, the software may be built in a Windows-based website.

I would like to know how to install and use the sms trial software. What are the requirments to use this software?

To use Headwind GSM Modem Driver, you need a mobile phone or GSM modem and Bluetooth or cable connection. If possible, ask the manufacturer whether the phone supports GSM AT commands or whether the modem supports sending SMS. Install Headwind GSM Modem Driver, then setup the GSM modem or mobile phone connection. Before sending SMS, setup the serial port name in accordance with the user manual. Then click 'Connect' in the Headwind GSM Modem Driver control panel. If everything will be good, you will be able to send and receive SMS.The OS is Windows 2000/XP/2003/Vista. If you will use Outlook add-in, Windows XP is recommended.

I need to know how a script runs on a window machine. How is it possible to develop a script that automatically checks a remote server continuously and sends a message to the network administrator whenever the server is down?

The script runs on Windows machine every minute using a 'scheduled task'. See http://www.h-sms.com/sms_alert.php for details. It is also possible to develop a script which checks a remote server. For example, it can use ping to check the server status. The details are here.

It is able to add a automatically resend/retry function for failed sms on gsm modem driver? Because i use a autonomic monitoring-server that sends sms without any manual intrusions.

There is a mechanism of notification on changing SMS status. Use method SendAndTrace() of the SMSMessage class. The COM event is sent to SMSDriver class, you need to handle it to check the SMS status. See http://www.h-sms.com/help/smsmessage.php for details.

Troubleshooting

Why the SMS is sent but is not delivered to the recipient's phone?

Please check that you have included the country code in the number, because some mobile operators do not deliver SMS to numbers in the local (national) format.

I have no Bluetooth on the PC. How to connect the mobile phone?

You can either use the cable connection, or buy a USB Bluetooth dongle (costs from $10). The Bluetooth modem drivers usually come with the dongle.

I have installed the modem, selected the port but I get the "Timeout" error message while connecting.

You probably need to setup a "Baud rate" for the modem. Open the Windows control panel (Start -> Control Panel), double-click "Phone and modem options", select the tab "Modems". Check that the modem is present in the list and it is connected to the COM port. Select the modem and click "Properties", then select the "Modem" tab. You will see a "Baud rate" combo box containing a number. Open the control panel of Headwind GSM Modem Driver, set the "Advanced" flag and enter the baud rate in an appropriate combo box.

I have connected the GSM device but it does not receive SMS.

Please note that the most of Nokia mobile phones do not allow to receive SMS to PC (see the list of supported devices for details). Some GSM devices must be setup manually to receive SMS. Open the control panel of Headwind GSM Modem Driver, select the "Properties" tab and uncheck the flag "Auto-detect optimal sending mode". Then select the "SMS" tab and select "Incoming SMS": polling. When this option is selected, the application will periodically ask the GSM device whether there are received SMS. Adjust the polling time if you wish.

The device is not stable. After sending 1-2 SMS, the "Timeout" error appears, and the device can't be connected again.

Not enough power supply in USB port or bad USB connection. Please avoid USB hubs, use USB port or powered USB hub instead. To restore the device functions, unplug it and plug back.

The software does not work on ZTE modems (in particular, ZTE MF112).

ZTE modems need proprietary commands to switch on the GSM module. Please open the control panel, check the box "Advanced port settings" and type AT+ZOPRT=5 in the "Custom initialization" field.
