rSIM, short for resilient SIM is a new evolution in SIM technology. It’s a unique and innovative SIM tech that keeps a backup of your existing SIM card and allows it to connect to another network when the first one goes down. It’s a great use-case scenario when you want to ensure consistent mobile connectivity in areas where one particular network can be activated when another’s signal strength goes down.
What is rSIM technology in SIM cards?
rSIM is a technology developed by UK-headquartered firm CSL Group to create a robust IoT connectivity scenario. The company wants to add resilient connectivity for devices to ensure that they are always connected.
Theoretically speaking, the rSIM lets you stay connected all the time. It’s designed to keep you always-on on the network. An rSIM tests your devices’ connection from a SIM and automatically switches the network during a network outage.
This innovative technology comes courtesy of CSL Group which claims that the rSIM’s patented tech lets it monitor and check its own network connectivity and switch providers (From Ntc to Ncell or vice versa) automatically when during a network disruption. Basically, this happens because rSIM lets a SIM store profile of two telecom companies’ networks on a single SIM card- its own and another. This means you have a backup of a SIM card’s connection within your other SIM. This ensures that you are always connected to mobile networks.

The Technology Already Has Tied A Few Partners
The technology is still new and many developments and innovations might be around the corner. But its applications have already begun. The Deutsche Telekom IoT and Tele2 IoT have become the first connectivity partners. It’s just a start though and it’s possible that rSIM will become a trend in the coming future. SIM technology is always in evolution and there are no limits to research and development to make it more flexible and capable.
We allow ourselves to take SIM cards and their functions for granted. But without them, our mobile phones remain as useful as a brick when it comes to cellular services. That is because without a SIM card, we can’t connect to 2G,3G, 4G, or 5G. That means we don’t get to use voice, SMS, or data services provided by telecom companies. So, whether it’s a physical SIM card, eSIM, or iSIM, they are extremely crucial for communication. And technology like rSIM is here to make sure we get the most out of them.
One of the reasons people use dual-SIM phones is that they can use two companies’ networks and also be able to continue using another network when one’s down. rSIM elevates this experience to a new level.

rSIM keeps a backup of another network in a SIM card
rSIM checks for the network from a SIM card itself and backs it up. But once a network goes down, it first lets the roaming network reconnect. When the roaming service is not subscribed or fails to re-establish the connectivity, rSIM comes to serve. If you use two SIM cards for the assurance of backup cellular service, rSIM will come fitting for you.
For the assurance of mobile network availability, you can continue using dual-SIM phones or eSIM that support multiple SIM profiles. But rSIM will be handy as well for a backup of a mobile network during a dead zone or network disconnection. Particularly, IoT/M2M could benefit from rSIM’s capabilities. Also noteworthy is that rSIM works perfectly fine with devices with dual SIM cards.
For the future, CSL Group is planning to make its new version of rSIM compatible with SGP.32 standards in 2025 which are essential for eSIM provisioning of IoT devices.

Is rSIM available in Nepal?
No, rSIM is not available in Nepal. rSIM is ostensibly a new technology and it’s only beginning in a select few companies in the Western world. But, the prospect would be interesting and amazing. Especially in remote areas or hilly parts, where the network might fluctuate, rSIM could be a vital tool to resort to. In fact, the technology could also reinforce the evolving IoT industry here.
But that doesn’t mean to say that there is no progress in SIM tech. Currently, eSIM is a dominant talk when it comes to keeping a SIM on a phone. Then, there is the iPhone 16 series that brings satellite connectivity for Emergency SOS service although it’s not yet available in Nepal. So, rSIM’s arrival could take some time maybe some years. In the meantime, check out all the information about eSIM and its benefits.
rSIM Vs. regular SIM?
Building on the theme of “resilient”, rSIM aspires to be different from a regular SIM. So, how is it distinct from the traditional cellular chip? It’s for the very purpose. rSIM is designed to deliver ‘always on’ connectivity. It always looks for a backup network stored on the SIM card and switches whenever needed.
The fact that an rSIM keeps two network profiles on the SIM, there’s little to almost no chance of a mobile user losing connectivity.
Also, with the resilient SIM, the device tests the data connection to determine if a connection has been lost. After finding it out, rSIM activates the backup profile stored on the SIM to restore the connection. Thales is the manufacturer of rSIM. It’s also the company that produces large bulks of SIM cards.
