3G Router Store – Fixed IP SIM Cards for Industrial IoT, Teltonika, and Secure Connectivity

A UK Pioneer in Cellular Router Solutions

Founded in 2008 by Millbeck Communications Ltd, 3G Router Store began as one of the UK’s earliest dedicated suppliers of industrial cellular routers and M2M connectivity equipment. Back then, the idea of using a mobile network for data was still emerging — and the original Teltonika RUT100 router helped define a whole new market.

Millbeck’s close partnership with Teltonika Networks started at the very beginning. When the first RUT100 arrived in the UK, it wasn’t yet a mainstream product — it was a rugged Lithuanian-made device designed for engineers, not consumers. 3G Router Store was among the first to recognise its potential for business-critical remote monitoring, CCTV, and industrial applications.

Over the years, as the range expanded — RUT500, RUT950, RUT955, RUT240, RUTX09, and now the RUTX50 5G router — Millbeck and 3G Router Store have remained at the forefront, guiding customers through every evolution in mobile connectivity.
Today, Millbeck is proud to be a Teltonika Diamond Distributor, the highest global recognition for technical expertise, sales performance, and long-term commitment to the brand.


From Hardware to Connectivity — the Evolution of Industrial IoT

In the early days, most routers were sold as standalone devices. Customers sourced their own SIM cards, often using consumer data plans with unpredictable performance and no visibility of the network path.
As the IoT sector matured, the need for reliable, secure, and manageable connectivity became just as important as the router itself.

This is where FixedIPSimCard.co.uk was created — as the connectivity partner to the hardware legacy of 3G Router Store.

Together, the two brands offer a complete ecosystem for industrial and IoT connectivity:


The 3G Router Store Legacy

When 3G Router Store launched, 3G was cutting-edge. Businesses were replacing dial-up lines and leased connections with 3G routers — small, powerful devices that could be installed anywhere.
Customers included CCTV installers, utilities, remote telemetry providers, and even emergency services looking for quick-deploy connectivity.

By 2012, as 4G LTE arrived, 3G Router Store had become the go-to source for reliable industrial routers. The Teltonika RUT500 became legendary for its stability and was followed by the RUT950, one of the most successful M2M routers in Europe.

The progression from 3G to 4G and now 5G reflects the same philosophy that’s guided the business since day one — stability first, speed second. Industrial customers don’t need gimmicks; they need consistent uptime, remote management, and trusted support.


Millbeck Communications – A Trusted UK Partner

Operating from Yorkshire, Millbeck Communications Ltd supplies routers, antennas, and connectivity to resellers, installers, and system integrators across the UK and Europe.
As a Teltonika Diamond Distributor, Millbeck offers complete product support, extended warranties, and deep technical knowledge.

Through its connected brands — 3G Router Store, 4G Router, 5G Store, and FixedIPSimCard.co.uk — the group delivers a seamless blend of hardware, software, and connectivity.

This integration means customers no longer need multiple vendors to get their systems online; they can source routers, antennas, and IoT SIM cards all from one trusted UK supplier with 15+ years of continuity.


Fixed IP SIM Cards – The Foundation of Secure Remote Access

Many industrial applications depend on being able to connect back to a device — whether to view a CCTV feed, access a PLC, or manage a router remotely.
Consumer data SIMs rarely allow inbound connections or offer stable addressing. That’s why Fixed IP SIM cards remain vital for professional IoT deployments.

A Fixed IP SIM Card provides:

FixedIPSimCard.co.uk supplies SIMs that work across multiple networks — including EE, O2, Vodafone, and Three — with access to private gateways and secure VPN infrastructure for full control of remote routers and devices.


IoT SIMs and eSIMs for Modern Deployments

As IoT devices scale globally, traditional SIM management becomes complex. That’s where IoT SIMs and eSIMs (embedded SIMs) come in.
They use eUICC technology, which allows remote SIM profile switching — meaning a single SIM can change carrier over-the-air without being replaced physically.

For installers and integrators, this means:

Millbeck’s IoT SIM solutions combine these advantages with optional Fixed IP, VPN access, and multi-IMSI roaming to suit everything from CCTV towers and smart transport to renewable energy sites and industrial telemetry.


Teltonika and the Importance of Secure Connectivity

Teltonika’s routers have always been built for industrial reliability — but their full potential is unlocked only when paired with the right SIM card and network management tools.

With a Fixed IP or VPN-secured SIM, features like Teltonika RMS, Modbus monitoring, or MQTT data transfer work reliably and securely, even behind firewalls or private NAT structures.
For remote applications, this is the difference between “connected” and “operational.”

FixedIPSimCard.co.uk provides SIMs that are pre-configured for secure operation with Teltonika routers, ensuring:


Roaming and Multi-Network Resilience

No single UK mobile network delivers perfect coverage. For critical IoT systems, downtime isn’t acceptable.
That’s why Millbeck offers Multi-Network Roaming SIMs, which automatically connect to the strongest available signal.

These are not consumer roaming SIMs — they’re built for M2M applications, with permanent roaming agreements, fixed or private IP options, and VPN routing for data security.

Typical use cases include:


Why Customers Trust the Millbeck Group

  1. Experience – Over 15 years working exclusively in industrial mobile connectivity.
  2. Expertise – Deep knowledge of Teltonika hardware and cellular networking.
  3. Support – UK-based engineers with quick email response (typically within one hour).
  4. Security-Focused – VPNs, private APNs, and dynamic addressing solutions.
  5. Continuity – The same team that sold the first RUT100 still advises customers today.

That continuity matters. It’s why thousands of UK businesses continue to rely on 3G Router Store, Millbeck, and FixedIPSimCard.co.uk for secure, managed connectivity.


FAQ

Q: Can I use a Fixed IP SIM in any Teltonika router?
A: Yes. All Teltonika routers — from RUT200 to RUTX50 — support Fixed IP and VPN SIMs. Setup is simple via the WebUI or Teltonika RMS.

Q: What’s the difference between a Fixed IP SIM and a normal data SIM?
A: Normal data SIMs use dynamic IP addressing behind NAT, making devices unreachable from the internet. Fixed IP SIMs use static addressing for secure inbound connections.

Q: Do you supply public or private IP SIMs?
A: Both. Public Fixed IP SIMs allow direct access, while Private IP SIMs use VPN tunnels for secure remote access without exposure to the internet.

Q: Do your SIMs work abroad?
A: Yes. Multi-network and roaming variants cover the UK and EU, with automatic network selection and cross-border connectivity.

Q: How can I order or get advice?
A: Contact the Millbeck team or visit 3GRouterStore.co.uk to discuss your router and connectivity requirements.
