IoT SIM Cards for Secure and Reliable Connectivity

Multi-Network | Roaming | eSIM | Public & Private IP Options

At Simwise, we specialise in IoT SIM solutions tailored for industrial and machine-to-machine (M2M) connectivity. Whether you’re deploying smart devices, sensors, routers, or mission-critical infrastructure, our IoT SIMs provide the flexibility, reliability, and control you need to stay connected—anywhere in the UK, EU or worldwide.

✅ What is an IoT SIM?

An IoT SIM (Internet of Things SIM) is a special type of SIM card designed for machines—not people. Unlike regular mobile SIMs, IoT SIMs offer enhanced network resilience, extended data session durations, remote management, and better integration with telemetry, sensors, and smart devices.

IoT SIM cards are engineered for long-term deployments in the field. From smart meters to digital signage, from CCTV to EV charging points—IoT SIMs power the modern connected world.

🌍 Roaming IoT SIMs for Global Reach

Our roaming IoT SIMs connect across multiple national and international networks. Devices using our SIMs can seamlessly roam between partner networks in over 180 countries, ensuring constant uptime, even in areas with weak signal from a single carrier.

Ideal for:

🔄 Multi-Network SIM Cards (UK/EU)

A multi-network IoT SIM ensures your device stays online by automatically switching between UK and EU networks such as EE, Vodafone, O2, and Three—based on signal strength, not brand.

Key benefits:

🔐 Private IP SIMs: Secure, Firewall-Protected Access

For secure M2M applications, Private IP SIMs route traffic over our private APN with no exposure to the public internet. You can connect via VPN into your private network or data centre to manage devices securely.

Used for:

🌐 Public IP SIMs: Easy Remote Access

If you need direct access to your device from the internet, our Public IP IoT SIMs come with fixed or dynamic public IP addresses, allowing:

📱 eSIM & eUICC: Flexible, Future-Proof Connectivity

eSIM (embedded SIM) technology enables over-the-air provisioning, letting you switch between providers without swapping hardware.

Our IoT eSIMs support:

Perfect for global device manufacturers and remote deployments where access is limited.

🌍 Multi-IMSI SIMs: One SIM, Many Identities

Multi-IMSI IoT SIMs dynamically switch identities based on coverage and performance. These SIMs hold multiple network profiles (IMSIs), automatically selecting the best one in real-time.

Benefits include:
