M2M SIM security
IoT Security is of the utmost importance when it comes to reducing the risk of your IoT devices being compromised. A private APN can be used to enable the secure M2M connection of provisioned IoT devices to your corporate network. By preventing your IoT infrastructure from being exposed to the entire public internet, you can rest assured that your vulnerability is kept to a minimum.
An IPSec VPN can also be applied to your M2M deployment in order to link two private networks over the public internet. The IPSec VPN does this securely by encrypting and authenticating all of the traffic being passed through the tunnel. Talk to our team to find out how InfiSIM can help maximise the security of your IoT solutions.
Know the difference.
Steered vs non-steered M2M SIMs
Unsteered or non-steered SIMs are multi-network SIM cards that are open to connecting to multiple networks whilst prioritising the one with the strongest signal. They are different to steered multi-network SIMs which are programmed to default to a parent network, even if a stronger network is available. At InfiSIM, all of our multi-network M2M solutions are unsteered.
Avoid bill shock.
Aggregated data pools
By aggregating your data across your SIM estate, you will have the flexibility to share data across all of your connected devices. If one of your devices is overusing data and another is under-using, they’ll both take data from the same pot. Rest knowing that the likelihood of you exceeding your data limit is far less likely with InfiSIM.

Roam the networks without restrictions.
Non-steered Global M2M connectivity
At InfiSIM, our multi-network roaming SIMs never default to a parent mobile network. We provide non-steered M2M connectivity, meaning our global M2M SIM cards are open to connecting to the strongest network available in your location.
By utilising Global M2M SIM cards that can seamlessly switch between networks (without prioritising one specific primary network), you will not only benefit from faster connectivity, but from increased up-time too. In fact, we pride ourselves on providing 99.98% up-time across all the major networks.

“We are market leaders in the manufacturing of mechanised forestry equipment. These machines run complex control systems for real time decision making during the processing of each tree and to collect vast amounts of sensor data related to machine performance. Machines are deployed to the most remote areas of the UK usually for several months at a time.
This presented a problem for our telematics software connections used for remote support sessions and general data traffic to and from our servers. We trialled several solutions with other suppliers with very little success due to reliability and stability of the products offered.
I researched and found InfiSIM who couldn’t have been more helpful. Their knowledge about their product was very impressive and gave me the confidence to authorise a few trials. We were receiving data from our machines when we couldn’t even get a proper phone signal. Perfect!
We now have over 100 machines running our telematics software and we often receive compliments that we are now also the market leaders in the telematics within our industry. This wouldn’t have been possible without the InfiSIM product.
Our InfiSIM products are monitored through NOVA. This system is brilliant and saves huge amounts of time managing the SIMs.”

By providing reliable, global connectivity, they enable real-time data transmission and remote management, transforming how businesses operate. Below, we explore key industry applications, complete with real-world examples and case studies to illustrate their impact.
A quick overview of M2M technology
M2M stands for Machine to Machine communication and it is the direct connection between two or more devices. There are endless applications of M2M technology, including payment terminals, pet tracking, smart street lighting, and many, many more.
Modern Machine to Machine communication has evolved into a system of networks in which data is traversed between devices. Information is sent from one device (or machine) via a central hub, before it reaches another device such as a mobile or computer. By traversing data between devices in this way, we are able to automate tasks and manage our operations remotely, increasing productivity.
Over the past 2 decades, mobile networks have expanded around the globe and the speed of M2M connectivity has greatly increased. This has worked hand-in-hand with the rapid growth of IoT technologies that provide remote, fast solutions to end-user issues.
What are M2M SIM cards?
M2M SIM cards, or Machine-to-Machine SIM cards, represent a pivotal advancement in connectivity solutions tailored specifically for the Internet of Things (IoT) landscape. These specialised SIM cards facilitate seamless communication between devices, enabling automated data exchange without human intervention. At InfiSIM, we design our M2M SIM cards to meet the rigorous demands of industrial and commercial applications, ensuring reliable performance in diverse environments.
Unlike traditional SIM cards, which are primarily used in consumer mobile phones for voice calls, messaging, and personal data usage, M2M SIM cards are optimised for data-centric operations. They prioritise low-power consumption, extended lifespan, and robust connectivity, making them ideal for devices that operate remotely or in harsh conditions. For instance, while a standard SIM might suffice for everyday smartphone use, it lacks the critical functionalities and management features that are essential for IoT deployments.
Key differences include durability: Industrial M2M SIMs are built to withstand extreme temperatures ranging from -40°C to 105°C, vibrations, and humidity, whereas regular SIMs are not engineered for such resilience. Management capabilities also set them apart; M2M SIMs support remote over-the-air (OTA) updates and centralised control via platforms such as our NOVA system, allowing for efficient fleet management of thousands of devices. In contrast, traditional SIMs require manual handling and offer limited remote oversight.
From a technical standpoint, InfiSIM’s M2M SIM cards support a broad spectrum of network technologies, including 2G, 3G, 4G LTE, 5G, NB-IoT, and LTE-M. This ensures compatibility with both legacy systems and future-proof innovations. Form factors vary to suit different needs: 2FF (standard), 3FF (micro), 4FF (nano), MFF2 (embedded solderable for permanent installation), and eSIM (electronically programmable for flexibility). Security features are paramount, with built-in encryption, private APNs, and compliance with standards such as GDPR.
Our M2M SIM cards also feature multi-IMSI technology for non-steered global roaming, connecting to the strongest available network in over 200 countries without carrier bias. This results in superior uptime & coverage, and reduced latency. Pricing models are flexible, with aggregated data pools starting at £0.50 per month, contrasting with the fixed, often higher costs of consumer SIM plans.
In essence, InfiSIM’s M2M SIM cards empower businesses to harness the full potential of IoT, from smart metering to asset tracking. By choosing our solutions, you gain not just connectivity, but a scalable, secure foundation for innovation. Request your free starter kit today to experience the difference.
How does M2M technology work?
All M2M solutions require an end-device that collects data (usually via a sensor or tracker), some form of connectivity to traverse the data, and another machine that receives this data. Once your second machine has received the data, it is either interpreted by software, people or the device itself, or it is relayed onto another machine.
A good example of M2M in the real-world would be a smart fridge. Smart fridges use sensors to analyse the contents of your fridge and ensure that you never forget to restock. When you are running low on a specific item, the fridge will add it to a virtual shopping list which will be automatically sent to your smartphone. In this situation, the data being traversed is related to the items on your virtual shopping list. Similarly, your smart fridge can analyse increases in temperature. If it detects a sudden rise, it will send the temperature data to your smartphone in the form of an alert. This way you can react and ensure that your fridge is closed properly.
Most M2M systems are usually made up of some or all of the following:
Machine-to-Machine connectivity
All M2M solutions require some form of connectivity to operate. Although some wired connections are considered to be M2M connections, most are wireless.
M2M SIM cards allow your machines to connect via the mobile networks. This enables you to deploy your devices anywhere in the world where there is cellular connectivity. For this reason, connecting your machines via the mobile networks is the most popular method of deploying an M2M solution. Solutions such as fleet tracking, digital motorway signage and remote CCTV etc. simply wouldn’t work without a mobile network connection.
