In the rapidly evolving world of the Internet of Things (IoT), reliable connectivity is paramount. Devices ranging from smart meters and asset trackers to autonomous vehicles and industrial sensors require continuous, seamless communication to function effectively. That’s where multi-carrier IoT SIM cards come into play. But what exactly are they, and how do they work? This blog dives into the concept, benefits, and functionality of multi-carrier IoT SIM cards.

Understanding IoT SIM Cards

Before diving into multi-carrier functionality, it’s essential to understand what an IoT SIM card is. Unlike traditional SIM cards used in consumer smartphones, IoT SIM cards are specifically designed for machine-to-machine (M2M) communication. They support a wide range of network technologies (2G, 3G, 4G, LTE-M, NB-IoT, and 5G), are often more durable, and can withstand extreme environmental conditions. These SIMs are typically deployed in devices that need to transmit data over long periods without manual intervention.

What Makes a SIM Card Multi-Carrier?

A multi-carrier IoT SIM card is capable of connecting to more than one mobile network operator (MNO). Unlike a traditional SIM, which is locked to a single carrier, a multi-carrier SIM provides access to multiple networks, either through a single profile with multiple network access agreements or by switching between different profiles stored on the SIM.

This flexibility is crucial for IoT deployments across different geographical regions where a single carrier might not have adequate coverage. A multi-carrier SIM ensures that the IoT device always connects to the best available network, enhancing reliability and uptime.

How Does a Multi-Carrier IoT SIM Work?

There are two primary methods by which multi-carrier IoT SIMs operate:

1. Network Steering (Roaming Agreements)

In this method, the SIM card connects to multiple networks using roaming agreements negotiated by the SIM provider. The card will prioritize certain networks based on availability, signal strength, or cost. The selection process can be dynamic or predefined by the SIM provider.

It is important to note, though, that not all multi-carrier SIM cards are created equal. Many providers, especially “native” SIM cards to a country, use a strategy called “network steering” to control costs. They prioritize certain networks, like their own network, over others because using a particular network costs less than using another available network. This will cause a problem because your device may get “stuck” on a network with a poor connection because it is the “preferred” network. When network steering is employed, you won’t be able to use the next preferred network until the coverage is completely missing from the more preferred network.

2. No Steering

No Steering SIM cards are by far the better choice for any IoT deployment. This type of IoT SIM card will allow the device to make the choice on which network to attach (usually based on RSSI value). You always want to check and make sure the SIM card you are deploying are no steering SIM cards.

Key Benefits of Multi-Carrier IoT SIM Cards

1. Increased Uptime and Reliability

By having access to multiple networks, devices can switch to the strongest or most reliable signal available, ensuring consistent connectivity.

2. Global Coverage

Multi-carrier SIMs enable devices to function across different countries and regions without needing separate SIMs for each locale. This simplifies logistics and reduces deployment complexity for global IoT projects.

3. Cost Optimization

Through intelligent network selection, multi-carrier SIMs can help manage and minimize data costs. Providers often offer competitive pricing models by leveraging various network agreements.

4. Simplified Management

Many multi-carrier SIM providers offer centralized platforms that allow users to monitor and manage their IoT SIM fleet in real-time. This includes data usage tracking, provisioning, & deactivation.
