The universal module for identifying the subscriber to a telephone line or data plan, known as USIM and SIM, is evolving. The size of traditional plastic SIM cards has decreased and embedded SIM cards or eSIMs are now incorporated into devices. The phrase “local SIM” has become a common term among international travelers, reflecting the widespread familiarity with swapping SIM cards abroad.
At this year’s Mobile World Congress (MWC), a new term, “rSIM” or Resilient SIM, emerged. This innovation marks a significant advancement in mobile technology, according to several telecommunications companies that have a vested interest in the new mobile platform.
During MWC, CSL Group demonstrated a revolutionary technology called rSIM, designed to improve network reliability. This approach integrates two independent mobile communication profiles into a single SIM card. This allows you to automatically switch to another network in the event of a connection failure and ensure continued connectivity.
This technology is similar to dual SIM cards but only requires one card
This technology is similar to dual SIM cards but only requires one card. It ensures seamless network transitions and is particularly useful for Internet of Things (IoT) devices in remote locations, where reliable connections are vital.
The first use of rSIM was announced just before MWC, when Deutsche Telekom and Tele2 of Sweden adopted the technology for IoT. The IoT communications landscape often extends beyond the coverage of conventional networks. Indeed, it often involves connecting services in remote locations and therefore more vulnerable to disruptions.
“This increase in disruption affects all industries, but the greatest impact is seen in critical sectors where lives and infrastructure are at risk, for example in the areas of telecare and critical national infrastructure (CNI)” , says Richard Cunliffe, Director of Product and Innovation at rSIM.
IoT connections expected to increase from two billion to seven billion by 2033
The sheer volume of physical connections in IoT also requires careful attention. According to a study last year, IoT connections are expected to increase from two billion to seven billion by 2033. This expansion highlights the importance of resilient technologies such as rSIM.
In this sense, rSIM would be crucial for industries that depend on IoT. Additionally, it could be vital for national infrastructure, ensuring consistent connectivity.
