Critical Data, SMS & Voice Connectivity
Lone-Worker Systems are different to other IoT SIM cards as they require resilient multi-network connectivity, combined with monitored voice calls. Dependent upon the device and Alarm Receiving Centre systems and protocols, this may require Mobile Originated (MO), Mobile Terminated (MT) or both forms of connectivity for devices. Calls and records need to be monitored in real time as response times are important and may form part of audits or investigations. It is also important that closed user systems are used so that spurious or nuisance calls or messages do not interfere with vital communication systems or channels.
