Which SIM is right for me? Choosing the right IoT SIM for your business
As the Internet of Things (IoT) continues to evolve, businesses are tapping into its potential to enhance functionality, increase efficiency, and streamline their day-to-day operations through smarter, connected systems.
However, many organisations struggle to choose the right connectivity solution. The number of options can be overwhelming if you are unfamiliar with the mobile network landscape or terms such as LTE, eSIM, or embedded SIM.
At iotie, we provide a range of business-ready IoT solutions and tools designed to meet your needs. Whether you’re managing a few connected devices or scaling to hundreds or thousands, we assist you in building secure, scalable IoT deployments. Here’s how to discover the right fit for your IoT project.
What is IoT?
The IoT refers to the expanding ecosystem of physical devices equipped with sensors and software that connect to the internet to share data. These devices, which range from industrial machinery to smart vending units, utilise network connectivity to provide real-time insights and automate processes.
In a business context, IoT facilitates device management, the connection of data between systems, and more informed decision-making, driving efficiencies, reducing operational costs, and enhancing the customer experience.
What are IoT SIMs used for?
IoT SIM cards provide the data connection that allows devices to communicate over cellular networks. Some typical IoT applications include:
- Logistics and Fleet Management – Track vehicle locations, monitor driver behaviour, and optimise routes using GPS and asset tracking tools supported by resilient cellular network coverage. Read more about IoT in fleet management here.
- Smart Agriculture – Deploy low-power sensors using NB-IoT or LTE-M to monitor soil conditions, crop health, and environmental data.
- Retail and Vending—Monitor stock levels and device status and deliver updates over the air, even in locations without wired broadband. You can find out more about IoT in retail here.
- Healthcare – Use IoT devices to monitor patient vitals remotely or ensure cold-chain integrity for sensitive supplies in transit. Read more about IoT in healthcare here.
- Automotive – Enable real-time diagnostics, remote tracking, and system updates using embedded connectivity and eSIM technology.
- Smart Cities – Urban areas worldwide rely on IoT-powered smart devices to power various municipal, recreational, and practical initiatives. Read more about smart cities here.
IoT SIM cards – designed for devices
Our IoT SIM cards are purpose-built for industrial and commercial IoT devices. They support various SIM form factors, including embedded SIM (eSIM) options.
IoT SIM card users benefit from low power consumption, extensive LTE, NB-IoT, and LTE-M coverage, as well as long-term global connectivity, among other advantages. These SIMs facilitate secure authentication, remote activation, and dynamic provisioning, making them perfect for smart meters, vending machines, and sensors.
Multi-network SIMs – always connected
Multi-network SIMs switch intelligently between available networks to ensure uninterrupted service. They are essential for any deployment where connectivity is critical, such as mobile security systems or vehicle fleets.
These SIMs minimise the risk of downtime, ensure more robust network connectivity, and facilitate roaming across various mobile network operators.
Business SIM-only mobile contracts – flexible and cost-effective
Need affordable mobile phone connectivity for your business?
Our SIM-only business mobile contracts are cost-effective, highly flexible, and designed for modern workflows. From field staff utilising mobile phones and tablets to connected kiosks and routers, these SIMs adapt to your requirements.
With transparent pricing, scalable data usage options, and no device tie-ins, it is an innovative solution for growing businesses managing hybrid or mobile teams.
Fixed-IP SIM cards – secure remote access
Fixed-IP SIM cards provide a reliable, static IP address for remote control and device management, enabling direct access to IoT endpoints, whether for surveillance, digital signage, or automation systems.
They are ideal for use cases that require continuous access through VPNs, firewalls, or static configurations. With advanced authentication and connectivity management, they provide secure and stable access from anywhere.
SIM management platform – total visibility and control
Managing a large IoT deployment across multiple regions or devices can become complicated quickly. That’s where our intuitive SIM management platform comes in.
You can monitor data usage, track SIM status, manage provisioning, trigger activation or suspension, and receive real-time alerts from one central dashboard. The iotie portal provides complete control over device management and enhances your visibility across all connected assets.
IoT routers – plug-and-play connectivity
Our industrial-grade IoT routers are engineered to operate in remote and rugged environments. They support dual-SIM configurations, multi-network fallback, and rapid LTE speeds, ensuring your IoT devices remain online and secure.
Whether deployed at a construction site, temporary retail unit, or remote warehouse, these routers provide a reliable data connection where traditional broadband can’t reach.
They are compatible with all our SIM options — including fixed-IP, multi-network, and embedded SIMs — to provide your business with maximum functionality and global connectivity.
