In today’s connected world, businesses can’t afford downtime. From payment terminals to remote sensors, the need for reliable, always-on internet has never been greater. This is where Roaming SIMs and IoT SIMs step in — especially when paired with an industrial-grade router like the Teltonika RUT206.
Let’s walk through a real-world scenario that shows why this combination is such a powerful solution.
The Challenge: Remote Equipment Needs Connectivity
Imagine you’re a facilities manager responsible for a chain of car parks. Each site needs:
- A secure connection for CCTV cameras
- A reliable link for ticket machines and payment terminals
- Remote monitoring of barrier gates and sensors
The problem? These locations don’t have fixed broadband lines — and even if they did, installation costs and delays could hold up deployment for weeks.
The Solution: Roaming SIM + Teltonika RUT206
Instead of waiting on fixed lines, you install a Teltonika RUT206 industrial 4G LTE router at each site. Inside the router, you insert a multi-network roaming IoT SIM card.
Here’s how it works:
- Automatic Network Selection
The roaming SIM connects to whichever mobile operator has the best coverage in that area (EE, O2, Vodafone, or Three in the UK). If one network drops, it simply switches to another. - Secure Connectivity
The RUT206 supports VPN tunnels (OpenVPN, IPsec, WireGuard), ensuring data from your payment terminals and cameras is encrypted end-to-end. - Industrial Reliability
Unlike consumer devices, the RUT206 is designed to run 24/7 in harsh environments. It can be wall-mounted inside a cabinet, powered from 9-30V, and managed remotely. - Remote Management
Using Teltonika’s RMS (Remote Management System), you can update firmware, change settings, and monitor connection health without visiting the site.
Benefits of This Setup
- Reduced Downtime: Always connected, even if one mobile network fails.
- Faster Deployment: Install today, go live today. No waiting for fibre or DSL.
- Scalable: Add as many sites as needed without the hassle of physical line installations.
- Secure by Design: VPNs and private IP SIM options ensure critical systems stay protected.
Beyond Car Parks: Other Use Cases
The same roaming SIM card + industrial router setup can be used across industries:
- Construction sites – instant internet for site offices and security cameras
- Retail pop-ups – reliable card payment systems anywhere
- Utilities – remote monitoring of pumps, meters, and substations
- Transport – connectivity for buses, kiosks, and roadside equipment
Final Thoughts
A roaming IoT SIM inside a Teltonika RUT206 (or any industrial router) creates a powerful, flexible, and secure connectivity solution. It’s the modern alternative to waiting for fixed lines, ensuring your business operations never stall.
