The SMS gateway software connects to the SMS center (SMSC) of the mobile service
provider in two possible ways: either with the help of a GSM modem
(GSM modem connection)
or over the Internet
(IP SMS connection).
- Option 1. GSM Modem Connection
In case of this option a GSM modem (or GSM phone) is connected to the server
Conserning connectivity you can use a
standard RS232 cable, a
USB data cable,
The standard RS232 cable is the most recommended to use because it can be
attached directly to your PC's COM port. The second option is a USB data cable.
For these cables you will need to install a driver that will create a virtual
serial port in your operating system. Bluetooth or IR connections are not
recommended since these wireless links are unreliable.
The SMS gateway software will control the GSM device (modem or phone) and SMS
messages are sent through this device. In this case SMS messages are forwarded
to the SMS network over the air. They are sent the same way as they are sent
when you use a traditional GSM handset for SMS messaging. If you use GSM modem
connectivity you need a SIM card that you can put into the GSM device (modem or
phone) for sending an SMS message. In this way, the price of the SMS messages is
determined by the price plan you have chosen when you purchased the GSM device.
The SIM card belongs to your GSM mobile service provider.
