How multi-carrier SIMs enhance IoT business operations

When the rise of IoT began in the early 2000s, it quickly became evident that the available one-size-fits-all solutions were inadequate. With traditional SIM cards locked to a single network, device connectivity became unstable when they moved outside the card’s designated coverage area. IoT deployments with single-carrier SIMs often stumbled when confronted with geographical or infrastructural hurdles. Devices in transit or deployed in diverse locations faced connectivity blackouts, undermining the very essence of IoT.

Today, there are over 15 billion connected IoT devices. And by 2030, there will be nearly 30 billion. As more and more businesses rely on IoT devices for critical business operations, the need for flexibility, adaptability, and unwavering connectivity has only grown.

From smart homes and wearable health devices to security and expansive industrial deployments, the fabric holding this intricate web of connections together is the technology behind it. In the case of the ever-expanding IoT network, that technology is the IoT SIM card.

But, not all SIM cards are created equal. That’s where multi-carrier SIM cards—designed to navigate the nuanced challenges of IoT operations—can help. Keep reading to learn more about how these SIM cards can take your business’s IoT operations to the next level.

What is a multi-carrier SIM card, and how does it work?

A multi-carrier or multi-network SIM is a piece of hardware that stores a Subscriber Identity Module (SIM). Unlike traditional SIM cards, which are restricted to a single network provider, multi-carrier SIM cards can house multiple carrier profiles by leveraging eUICC (Embedded Universal Integrated Circuit Card) technology.

When a device equipped with a multi-carrier SIM card tries to establish a connection, it doesn't just connect to a pre-defined network. Instead, it scans the area for available networks and chooses the best one based on signal strength, network congestion, and other predefined parameters. If, for some reason, the chosen network experiences interruptions or a drop in quality, the SIM seamlessly switches to another available network profile, maintaining an uninterrupted connection.

By dynamically switching between networks, multi-carrier SIMs remain perpetually in search of the best available signal. Whether it's a bustling city center or a remote countryside, these SIM cards strive for optimal connectivity, ensuring your IoT devices remain online and functional. You can even configure some multi-carrier SIMs (like Telnyx’s IoT SIM cards, for example) to prioritize networks based on your unique preference.

Ultimately, using multi-carrier SIM cards is like having multiple SIM cards in one—without the physical hassle.

The benefits of multi-carrier SIM cards for business operations

The ability to dynamically switch between networks based on connection strength and stability has more benefits than uninterrupted connections. Below, we’ll look at some of the main benefits businesses can experience by leveraging multi-network SIM cards.

Increased device uptime

Traditional SIMs often grapple with network blind spots. Multi-carrier SIMs, with their dynamic network-switching capability, ensure devices are always up and communicating. With the flexibility to switch between networks, devices experience minimal downtime.

Cost efficiency

Businesses can incur hefty roaming charges when devices like delivery trucks or drones crisscross borders. Multi-carrier SIMs intelligently switch to local networks, so you can bypass exorbitant roaming charges and save money on mobile deployments.

Scalability

Imagine the logistical nightmare of replacing SIMs every time your business wants to expand to a new region. Multi-carrier SIMs eliminate this hassle, ensuring devices remain connected regardless of location, with no need to swap out SIMs for different locales.

Improved data collection

Consistency is key in making data-driven decisions. Uninterrupted connectivity ensures consistent real-time data collection, which is paramount for applications such as remote monitoring. With persistent connectivity, you can rest assured of a continuous stream of data to make accurate, real-time decision-making easy and reliable.

Enhanced customer experience

A stable connection guarantees seamless customer experiences for IoT devices that directly interface with customers. Consider a retail scenario where an IoT-enabled PoS system fails due to connectivity issues. With multi-carrier SIMs, such scenarios are a thing of the past, ensuring customers always leave satisfied.

IoT business applications of multi-carrier SIMs

Organizations in many industries can experience the benefits of robust IoT networks. Below, we’ll discuss a few use cases where multi-carrier SIMs can make a massive difference over traditional SIM cards.

Supply chain and logistics

If you’re tracking goods across continents, multi-carrier SIM cards ensure you're always in the know, optimizing routes and ensuring timely deliveries. They also ensure efficient cargo movement and effortless fleet management, regardless of location. This technology can also provide data for predictive analytics, helping businesses preempt potential logistical challenges.
