Why Fully autonomous, resilient SIM connectivity?

rSIM is a revolutionary SIM solution designed to address the rising issue of network outages affecting critical IoT applications. With built-in dual-core resilience and intelligent profile switching, rSIM ensures uninterrupted connectivity by seamlessly switching between two independent mobile operator profiles stored on a single SIM card. This technology significantly reduces the risk of outages and minimises downtime, keeping essential devices online when it matters most.

Benefits

Built-in dual core resilience, guaranteeing maximum uptime
rSIM tests the data connectivity to detect and react to problems faster
rSIM allows enough time for the device to roam to other networks
If loss of connection persists, rSIM switches to a second MNO core
After 24 hours, rSIM will automatically revert to main profile (providing fixed)

Featured Capabilities

Designed for 'always on' reliability

rSIM guarantees maximum uptime by using full autonomous dual core infrastructure embedded within the rSIM.

Built on GSMA standards & trusted by global operators

rSIM is built on GSMA standards, ensuring interoperability and long-term support across a wide range of devices and mobile networks. This architecture allows rSIM to protect against a broad range of failure scenarios, including zero-byte sessions and silent disconnects.

Autonomous connectivity testing

rSIM achieves high availability by running a lightweight applet on the SIM that performs continuous connectivity polling, typically every 60 seconds, though this is configurable. These polls are not just signal checks; they confirm end-to-end data flow by testing actual packet transfer.
