IoT SIM Cards for Global Device Connectivity

Connectivity decides whether your devices work in the field or sit dark. OV’s IoT SIM cards give product teams, OEMs and resellers one SIM that holds a connection across borders and carriers, for the life of the device, managed from a single platform and running on our own network core.

The challenge

Global Connectivity Without the Guesswork.

The hard part of an IoT deployment is rarely finding a SIM. It is keeping thousands of devices connected consistently once they are in the field. Stitching together local carriers or multiple SIM vendors leaves coverage gaps, billing that does not reconcile and little visibility into performance. An OV IoT SIM removes that fragmentation: one SIM, one platform and one commercial relationship behind every device.

The OV solution

One Network Core, Built In-House.

OV runs as a true IoT MNO, so your SIMs connect directly to our network core rather than through an aggregator. That is what sits behind the predictable performance, the direct roaming reach and the single view of every connection in OV ONE, our in-house connectivity management platform. You manage the whole estate, from one SIM to many thousands, in one place.

Explore OV ONE

180+ countries and 600+ networks

Multi-IMSI architecture for best-available network selection

Flexible data pools and SIM group management

Full visibility via the OV ONE dashboard and APIs

Enterprise-grade security with IoT SAFE, IMEI Lock, and geofencing

IoT devices

Designed for IoT Devices.

An OV IoT SIM is engineered for devices that ship once and run for years, not for handsets. It is built for long lifecycles, low and predictable data use, and consistent behaviour across device types and environments. The SIM comes in standard, embedded and integrated forms and the same SIM runs across these deployments:

01

Fleet and vehicle telematics

02

POS and payment systems

03

Industrial and asset tracking

04

Telecare and safety devices

Security

Security on the SIM and in the Network.

Security sits on the SIM and in the network, not bolted on after deployment. OV ONE lets you provision and cease SIMs instantly, lock a SIM to a single device, isolate traffic over a private APN, and control where a device can connect and what it can reach. The controls below span the SIM, the application, the network layer and traffic filtering.

Platform Security:

  • Instant SIM Provisioning & Ceasing: Enable or disable service instantly to prevent fraudulent usage until SIMs are in secure environments
  • Custom Monitoring & Alerts: Real-time notifications for suspicious behaviour or status changes across your SIM estate
  • Session-Level Control: Activate, pause, and monitor every SIM in real-time via OV ONE

Application Security:

  • IoT SAFE: GSMA-standard “Root of Trust” providing secure element on SIM for trusted data communications
  • IMEI Lock: Tie SIMs to specific devices, preventing fraudulent use if removed from IoT hardware
  • SIM Applets: Programmable security applications for encryption, authentication, and secure transactions
  • Geofencing: Virtual boundaries with instant alerts when devices move outside defined areas

Network Layer Security:

  • Public APN: Standard secure internet access supported by global MNO infrastructure
  • Private APN: Bespoke network gateway for isolated, secure traffic routing tailored to your requirements
  • VPN Support: Encrypted communication tunnels for healthcare, financial services, and sensitive data applications
  • Fixed IP Addressing: Consistent IP addresses for reliable device monitoring and management
  • Dynamic IP Addressing: Cost-effective IP assignment with address recycling for large estates

Whitelisting & Blacklisting:

  • Data Traffic Filtering: Lock devices to approved IP addresses and URLs, preventing unauthorised endpoint communication
  • SMS Filtering: Control which mobile numbers can send/receive messages to/from devices
  • Voice Barring: Remove voice capability to prevent premium-rate fraud and unauthorised calls

Technical benefits

Built on a True IoT Network Core.

Because OV owns and runs the mobile network core, your SIMs sit on OV infrastructure end to end rather than on access resold through a third party. That means direct roaming relationships, fewer parties between a fault and a fix, and full control of how your data is routed. The same SIMs support eUICC today and are designed to move to SGP.32 orchestration through OV ONE as the standard matures.

Technical Capabilities:

  • In-house managed network core with direct HLR/HSS integration
  • GSMA-compliant roaming agreements across 600+ networks
  • Multi-IMSI technology for automatic best-network selection
  • Non-steered SIM technology without restrictive PLMN lists
  • Support for 2G, 3G, 4G/LTE, NB-IoT, and LTE-M technologies
  • API-first architecture with full programmatic access to all features
  • Real-time session monitoring with 31 days historical data
  • Bulk operations supporting up to 1,000 SIM activations at once

Integration & Automation:

  • AWS IoT integration for cloud-native deployments
  • HTTP POST endpoints for webhook automation
  • RabbitMQ message queue integration for event-driven architectures
  • SMTP email alerts for usage thresholds and system events
  • Complete API documentation at docs.worldov.com/reference

Common Questions About OV IoT SIMs.

An IoT SIM card is a SIM made for connected devices rather than phones, built for long deployments, remote management at scale and access to more than one network. An OV IoT SIM adds a direct connection to our own network core and full control through OV ONE. For the general definition and how the technology works, see our IoT connectivity glossary.

IoT SIMs are designed for devices, not handsets. They are built for long lifecycles, low data rates, and continuous remote operation with enhanced security features like IMEI Lock and IoT SAFE.

A standard SIM is built for one person, one handset and one home network. An IoT SIM is built for unattended devices over much longer lifecycles, with multi-network access, remote provisioning and fleet-scale management. We cover the differences in full, from network behaviour to security, in IoT SIM vs Normal SIM.

OV uses flexible commercial models designed to fit how you deploy, rather than a single fixed tariff. Charges are structured around activation, active and provision fees, with platform and support plus any voice or SMS usage billed separately, so cost tracks your actual deployment. You set data caps and monitor spend per SIM in OV ONE. Talk to our team for a model matched to your volumes and use case.

Most teams move across in phases rather than all at once. You can request test SIMs to validate coverage and behaviour in your own devices first, keep production and test environments separate on the platform, then migrate live devices as you gain confidence. Our team supports the switch and helps map your existing setup onto OV ONE.

You can request a free trial SIM and test OV connectivity in your own devices, environments and markets before you commit. The trial uses the same connectivity as live OV deployments, not a sandbox, so what you see is what you get in production. Start with a free IoT SIM trial, or book a demo if you would like a walkthrough first.

Yes. OV ONE is API-first, so every action you can take in the dashboard, activating, suspending, grouping and monitoring SIMs, is available programmatically. Teams that run connectivity from their own systems can automate provisioning, usage alerts and reporting through the OV ONE API. Full documentation is available for your developers.

OV IoT SIMs support IoT SAFE, the GSMA root-of-trust standard that places a secure element on the SIM, and IMEI Lock, which binds a SIM to a specific device. Traffic can run over a private APN for isolated routing, with geofencing and traffic filtering to control where a device connects and what it can reach. These controls are configured and monitored in OV ONE alongside the rest of your estate.

Yes. OV’s IoT SIMs connect to over 600 networks across 180+ countries with support for 2G, 3G, 4G/LTE, NB-IoT, and LTE-M technologies. See the full country and network list on our Coverage page.
