IoT eSIMs & SIMs

Reliable Connectivity for Connected Devices

IoT eSIM and SIM solutions designed to support large-scale device connectivity across locations and networks, in any business environment.

Pentagram enables organisations to connect, manage, and scale IoT deployments with consistent performance and centralised control.

What We Offer

IoT Connectivity Built for Scalable Deployments

IoT deployments need reliable, always-on connectivity across regions, devices, and network conditions. At scale, that raises challenges around coverage, cost control, security, and visibility.

Pentagram provides IoT SIM and eSIM solutions designed for long-term device deployments. Connectivity is delivered through major networks with flexible data models and centralised management, so organisations can deploy connected devices locally or globally while retaining full control.

Flexible IoT Connectivity at Scale

IoT eSIM and SIM solutions are built to support large volumes of devices with consistent connectivity and simplified management. We combine multi-network access, flexible data options, and centralised oversight so your business can scale as deployments grow while keeping reliable IoT operations across environments.

Core capabilities include:

  • Global & Multi-Network Connectivity Connect devices across regions with access to multiple mobile networks for improved coverage and resilience.
  • Flexible Data Models Choose per-MB, pooled, or bundled data options based on device behaviour and usage patterns.
  • Real-Time Usage Monitoring Track data consumption, device activity, and connectivity status from a central platform.
  • Scalable SIM & eSIM Deployment Add, suspend, or modify SIMs and eSIM profiles as device volumes change.
  • Deployment-Specific Configuration Configure connectivity based on device type, location, and operational requirements.

Why Pentagram

Pentagram helps organisations simplify IoT connectivity with a structured, scalable approach to device onboarding, usage management, and global deployment. As IoT environments grow, maintaining visibility and control becomes essential.

We centralise IoT SIM and eSIM management so connectivity aligns with your organisation’s needs and operational overhead is reduced. Businesses can maintain consistent performance, avoid fragmented supplier models, and improve reliability, cost control, and efficiency.

FAQs

What are IoT SIMs and eSIMs? +
IoT SIM and eSIM solutions provide connectivity for Internet of Things devices—for example smart meters, trackers, sensors, and industrial equipment your business relies on.
How are IoT SIMs different from standard mobile SIMs? +
IoT SIMs are built for long device lifecycles, lower data usage patterns, remote management, and unattended operation. They are designed to remain active and manageable over many years without frequent physical intervention.
What is the difference between an IoT SIM and an IoT eSIM? +
An IoT SIM is typically a removable physical card inserted into a device and optimised for IoT use cases. An IoT eSIM is an embedded chip fitted during manufacture, enabling remote profile management without swapping a physical card.
Can IoT SIMs operate across multiple networks? +
Yes. We support multi-network connectivity on major networks so devices can connect to available networks to improve coverage and resilience.
How is IoT data usage managed? +
IoT data can be monitored and managed through centralised management for all connected devices.
When should an organisation choose an IoT eSIM over a physical IoT SIM? +
IoT eSIMs suit large-scale or global deployments where physical SIM replacement is impractical. They enable remote profile management and are commonly embedded during device manufacturing.
