This was an SMS-based emergency response system that was used to supplement an expensive pager system. The system was designed to meet the specific situation and requirements of that particular RFS station.
The station had some members with older phones (“Think Nokia 3310”) so a web-only interface or mobile app wouldn’t work. It also had to be simple to use, people needed to be able to respond quickly without having to type out long messages. As this was an emergency situation, the time between sending and receiving messages and service downtime was also an issue.
