IoT SIM cards for connected devices
Multi-network IoT SIMs switch between providers to prevent downtime.
Rugged, industrial-grade SIMs withstand harsh temperatures and environments.
Monitor, manage, and secure your IoT SIM cards with an advanced online portal.
IoT SIM card: why choose one over a standard SIM?
Standard mobile SIM cards are designed for people. IoT SIMs are designed for machines.
While a consumer SIM works well in a phone, it isn’t built for always-on devices, long-term deployments, or remote management at scale. IoT SIM cards are purpose-built for connected devices. Benefit from:
- Multi-network access to help devices stay connected when signal strength changes
- Remote provisioning and lifecycle control, so SIMs can be activated, suspended or reconfigured without physical access
- Long-life durability for harsh or extreme environments
- Scalable commercial models, designed for estates ranging from a handful of devices to thousands
For organisations deploying connected technology across sites, regions or fleets, IoT SIMs provide greater resilience, visibility and operational control than consumer alternatives.
The benefits of IoT SIM cards
Reliable, always-on connectivity
IoT SIMs connect to multiple networks. If one network fails, the SIM automatically switches to the strongest available signal to prevent downtime and keep operations running smoothly.
Built for the extreme
Constructed with rugged materials and industrial-grade silicon, an IoT data SIM card can endure harsh vibrations, moisture, and temperatures. From -65°C to +150°C, they remain operational.
Longer lifespan
IoT SIMs support up to 26 million read/write cycles. Their longevity is a significant improvement on consumer SIMs, which reduces replacement costs and improves device reliability.
Flexible data plans
IoT data SIM plans are customisable to your business needs. From usage caps to pooling data across multiple devices, you maximise your budget and avoid unexpected charges.
Advanced security features
Private APN options. VPN support. Remote locking capabilities. These security features prevent unauthorised access and keep your sensitive data safe when being transmitted.
Full visibility and control
Gain real-time insights into SIM usage through an online management portal. You can use this data to set alerts and generate reports.
Advanced IoT SIM management portal
Take full control of your IoT connectivity through our secure, centralised online platform. Monitor data usage in real time, set alerts, generate performance reports, and remotely lock SIMs to protect against unauthorised access.
Automated management tools and detailed usage insights help you refine your operations, maintain oversight across your estate, and avoid unexpected costs.
Whether deploying global IoT eSIMs internationally or managing local devices, the portal delivers consistent visibility and control across every connected asset within your estate.
Flexible IoT SIM plan options for every business
Our IoT SIM plans are designed to adapt to your operational needs.
Unlike rigid consumer data plans, we offer customisable data allowances with pooling across multiple devices - helping prevent overages while maintaining cost control.
Plans reset each billing period, so you only pay for the data you use. With 4G and 5G IoT connectivity options available, businesses benefit from reliable, high-speed transmission for critical applications, supporting deployments of any size.
IoT SIM cards use examples
Security and CCTV
A global IoT SIM card enables secure, wireless CCTV connectivity. It means real-time surveillance in remote or urban locations is possible without relying on fixed broadband.
Retail
A 4G IoT SIM enhances inventory management and supply chain visibility. With this SIM, retailers can track stock levels and optimise logistics in real time.
Healthcare
An eSIM for IoT devices supports remote patient monitoring. An IoT eSIM achieves continuous data transmission for wearable health devices and emergency response systems.
Digital advertising
With an eSIM IoT solution, this can enable the remote management of digital signage. You can update advertisements and display content in real-time from a central location.
