An SMS hub is a stand-alone system which allows you to send and receive large numbers of text messages via the mobile phone network, without needing to be connected to the internet or to any other computer network.
You need a laptop or desktop computer with a number of mobile phones or GSM modems attached. A GSM modem is a small device without a keypad or screen that you connect to your computer. It works like a mobile phone, but is controlled through the computer. Messages are sent and received using software installed on the computer which transmits them through the attached phone or modem to the available mobile phone network. Because SMS hubs do not need to be connected to the internet, they are very useful for NGOs working in areas where access to the internet is not possible or is unreliable.
