SMS messaging with a mobile phone attached to the PC
If you plan to send/receive less than
15 000 SMS messages per day, a good option is to attach a GSM phone or GSM modem
to your PC. The GSM phone must be equipped with a SIM card that
has good tariff for SMS messages. The GSM phone can be attached
with a data cable, with an InfraRed port (IR) or with a BlueTooth (BT)
connection. With this setup you can use a computer program such as Ozeki
Message Server to send/receive SMS messages. The computer program in this
case uses the attached device to communicate with the GSM network.
Sending an SMS message using a cell phone takes about 5-6 seconds. Receiving takes about the same time. A good software, such as Ozeki Message Server allows you to attach more than one device to your PC and to use them simultaneously to increase capacity.
The best option to connect a phone to the
PC is to use a standard RS232 serial cable. USB cables, InfraRed and BlueTooth
connections are not that reliable. You can read more about the connection
methods on the following pages:
