Draft:Resiliant SIM

From Wikipedia, the free encyclopedia

rSIM (Resilient SIM) is a SIM card designed to improve mobile connectivity for Internet of Things (IoT) devices. It was launched in February 2024 by CSL Group[1][2] based in the United Kingdom.

The inventor of the patented technology was Richard Cunliffe[3] a Director at CSL Group.[4] CSL Group used Thales[5] to develop the rSIM. Deutsche Telekom IoT[6] and Tele2 IoT[7] were the first two mobile operators installed on the rSIM.

Key features of rSIM:

  • Resilience: rSIM is a SIM card that has two mobile operator profiles pre-installed on the SIM. The rSIM is also testing the Internet connection is working directly from the SIM. This allows for an automatic switch between the mobile operator profiles in the case of a connection failure to ensure continuous connectivity.[7]
  • Dual SIM functionality: It's like having two SIMs cards in one, from two completely different mobile operators, using different core infrastructure.[8]
  • Seamless roaming: rSIM allows for seamless roaming outside of a device's home country, providing further connectivity resilience.[9]
  • Standards Based: rSIM is an eUICC SIM, based on the GSMA SGP.02 standard[10]

Benefits of rSIM:

  • Reduced risk of disconnection for critical IoT devices used in sectors like telecare and critical national infrastructure.[11]
  • Improved uptime for all IoT devices relying on cellular connectivity.[12]
  • Mitigates disruptions caused by mobile network outages.[13]

Potential Applications:

  • Industrial IoT applications where reliable connectivity is essential.
  • Remote monitoring and control systems where a real-time, always-on connection is required.
  • Telecare and medical devices.
  • Any application where uninterrupted cellular connectivity is critical.

rSIM is a new technology, and its long-term impact on the IoT market remains to be seen.

Alternatives to rSIM:

  • UICC / eUICC Roaming SIMs - Allows roaming access to multiple networks outside of the country the SIM orginates using a single mobile operator core infrastructure
  • Multi-IMSI - A non-standards based SIM card that wraps multiple mobile operator IMSIs into a single profile. Provided by MVNOs with a single core.[14]
