GSM modem connectivity
SMS sending and receiving feature from and to your computer is available with a GSM modem or a mobile device using Ozeki NG SMS Gateway. With this solution you can create a connection to the mobile network simply and at a lower price. If you wish to know more details about implementing this idea please read below.
How to configure a GSM phone or GSM modem connection
With the use of this solution you do not need to connect
over the Internet to transmit SMS text messages. This process is very quick
therefore you gain the advantage of saving time and money. Furthermore, Ozeki NG SMS Gateway
possible to attach more than one device to the computer. In this way capacity can be increased.
If you usually do not send more than 15 000 messages per day you can use Ozeki NG SMS Gateway with a GSM modem or mobile device connected to your PC to use SMS functionality. In this case the Ozeki software communicates with the mobile network through the attached device in the following way: if the gateway sends a message, at first it arrives at the GSM device and after this it is transmitted to the SMSC of the GSM service provider over a wireless link (Figure 1).
In case of receiving a message, the GSM device keeps it in its memory or its SIM card. Ozeki NG SMS Gateway gets the notification about this process. The SMS gateway reads this message and wipes out it in order to create more place for the next incoming messages. The GSM device can be connected with a phone-to-PC data cable (USB or a serial RS232 cable), BlueTooth, or InfraRed. The modem or cellphone comes with a SIM card and its number will be the phone number the messages are sent to. You can check the list of suitable GSM devices on the Supported phones page.
