The Numbers Behind the Shift to IoT SIMs

Consumer SIMs were never designed for machine connectivity. These figures show why the industry is switching.

54M Active IoT/M2M SIMs in the UK +12% vs 2024
8B Global Connected IoT Devices +19% vs 2024
500MB Avg IoT SIM Data Usage per Month +35% vs 2024
68% Of Deployments Using Multi-Network Sharp rise
61% Enterprise SIMs Using Fixed IP / Private APN Security priority

Why Unsteered Multi-Network Matters

Most IoT SIMs quietly steer your device to a preferred network - even if the signal is poor. Ours don't.

✕ Steered SIMs
  • Locked to one preferred network
  • Switches only when that network fails entirely
  • Performance suffers in weak signal areas
  • You have no visibility or control
✓ Unsteered IoT SIMs
  • Always connects to the strongest signal
  • Seamless failover across EE, O2, Vodafone, Three
  • 99.9% UK population coverage
  • No compromises, no network bias

What Makes Our IoT SIM Cards Different

Eight capabilities that set professional IoT SIMs apart from anything you'd buy on the high street.

Multi-Network UK Coverage

Connects automatically to the best available signal - EE, O2, Vodafone or Three - giving full national resilience.

Fixed Public or Private IP

Essential for remote access, port forwarding, and VPN tunnels.

  • Public Fixed IP - CCTV, telemetry, maintenance
  • Private Fixed IP - isolated VPN-only networks

Private APN and VPN Integration

Create your own secure private network. Traffic never touches the public internet, reducing attack surface significantly.

Global and EU Roaming

Deploy devices anywhere without swapping SIMs. Single-tariff options cover 600+ networks worldwide across 190+ countries.

Flexible Data Plans

Plans from 1 GB to 500 GB per month. Shared data pools available so one bundle covers an entire multi-device deployment.

Online Management Portal

Activate, suspend, monitor usage, and set data alerts in real time - 24/7 access for complete fleet visibility.

5G, LTE-M and NB-IoT Ready

Works across modern cellular bands. Compatible with Teltonika, Siretta, and Proroute routers out of the box.

Security by Design

Network-level firewalls, VPN support, and encrypted links. eSIM (eUICC) provisioning available for remote profile management.

Typical Applications

From 10 smart meters to 10,000 CCTV units - our IoT SIM cards scale to your deployment.

Smart Metering and Utilities

Low-power M2M links for energy, water, and gas networks at scale.

CCTV and Security Systems

Remote video feeds over fixed IP or VPN with guaranteed uptime.

EV Charging Networks

Payment terminals and status telemetry across charging infrastructure.

Fleet and Asset Tracking

Multi-network coverage across UK and EU for vehicles and high-value assets.

Industrial Automation

Factory SCADA, PLC, and remote monitoring over secure private APNs.

Agriculture and Environment

Sensors deployed in rural or low-signal areas where one network isn't enough.

Retail and POS Terminals

Card terminals and digital signage with resilient always-on connectivity.

ANPR and Traffic Systems

Roadside cameras and enforcement systems requiring fixed IP access.

Why UK Businesses Are Switching to IoT SIMs

2G/3G shutdowns, 5G rollout, and rising security standards are forcing the change. These are the six reasons businesses are moving now.

1

Security First

Consumer SIMs expose devices to public internet risks. Private APNs keep traffic off the open internet entirely.

2

Multi-Network Resilience

Keeps remote sites online when one network has issues. No manual intervention required.

3

Fixed IP Management

Essential for VPNs, remote access portals, and centralised monitoring dashboards.

4

5G and LPWAN Growth

IoT SIMs now support RedCap, LTE-M, and NB-IoT - future-proofed for the next decade.

5

2G/3G Sunset

Legacy M2M devices must migrate to 4G/5G now. Leaving it late means unplanned downtime.

6

Cost Efficiency

Shared data pools reduce waste across large fleets. One plan, multiple devices, one bill.

Frequently Asked Questions

A SIM engineered for machines and routers - built to provide secure, always-on data connectivity for IoT and M2M applications. Unlike consumer SIMs, they support fixed IP addressing, private APNs, and multi-network roaming.
Not recommended. Consumer SIMs are frequently blocked in industrial routers, lack fixed IP or VPN support, and carry no SLA for uptime or data continuity.
All four major UK networks - EE, O2, Vodafone, and Three - plus over 600 international partners covering 190+ countries for global roaming deployments.
Yes. Choose between public fixed IP (for remote monitoring, CCTV, and telemetry access) or private fixed IP (for fully isolated networks reachable only via VPN).
Fully. They support 4G LTE, 5G NSA/SA, LTE-M, and NB-IoT bands - compatible with current and next-generation IoT hardware.
Yes. The management portal lets you activate, pause, monitor usage, and set data alerts across your entire SIM fleet in real time, 24/7.
Yes. Remote profile provisioning is available for eSIM-enabled routers and devices, allowing SIM management without physical access to the hardware.
Yes. Data pooling is available so a single bundle is shared across multiple devices - ideal for fleets where usage varies by device from month to month.
