The Future of EV Charger Manufacturing: Why OEMs Are Integrating GleeSIM IoT Connectivity

As the global EV market advances at record speed, charger manufacturers face increasing demands for smarter systems, robust performance, and uninterrupted connectivity. As charging networks scale into tens of thousands of locations, manufacturers must ensure their hardware remains operational regardless of local broadband constraints.

Traditional Wi-Fi and fixed-line connections often fail to meet these requirements. Installations in underground car parks, remote roadside sites, rural areas, or commercial facilities frequently suffer from unstable broadband or poor Wi-Fi penetration.

This is why leading EV charger manufacturers worldwide are turning to GleeSIM’s purpose-built IoT SIM solution — engineered to provide unmatched reliability, security, and plug-and-play deployment for next-generation EV charging hardware.

GleeSIM: Engineered Connectivity for Intelligent EV Charger Hardware

GleeSIM provides a specialised IoT SIM designed for EV chargers, enabling embedded, always-on connectivity directly through the charger router or communication module.
Our solution is widely adopted by OEMs who require:

Non-steered roaming for maximum uptime
Secure APN and encrypted traffic paths
Effortless integration with OCPP platforms
Reliable communication even in broadband-poor environments

With Plug & Play activation, manufacturers can ship hardware pre-configured and ready for field installation — reducing installer workload and improving customer satisfaction.

Why EV Charger Manufacturers Are Integrating GleeSIM at Production Level

Below are the strongest advantages for OEMs embedding our IoT SIM technology directly into their hardware design.

1. Guaranteed Connectivity in Any Location

IoT SIMs ensure chargers remain connected in:

Rural charging points
High-density urban environments
Underground or concrete-shielded locations
Motorway service stations
Commercial sites with limited broadband

The ability to deploy hardware anywhere, without depending on site infrastructure, gives manufacturers a significant competitive edge.

2. Non-Steered Roaming: The Strongest Network at All Times

Non-steered roaming allows the SIM to automatically select the strongest available mobile network, ensuring:

Maximum uptime
Reliable OCPP communication
Stable app integration
Fewer site visits due to connectivity failures

GleeSIM eliminates the risk of relying on a single mobile operator.

3. Enhanced Security & Isolation From Public Networks

EV chargers are high-value infrastructure and increasingly targeted for cyberattacks.

GleeSIM provides:

Encrypted communication channels
Private APN options
Isolation from consumer Wi-Fi
Reduced exposure to shared networks

Manufacturers can offer their clients a more secure, tamper-resistant charging solution.

4. Facilitating Real-Time Charger Intelligence

Our IoT SIM enables continuous cloud communication for:

Live charger status
Fault diagnostics
Predictive maintenance
Usage analytics and load distribution
Over-the-air firmware updates

This transforms standard chargers into smart, autonomous energy assets.

5. Plug & Play Integration for Zero-Friction Deployment

GleeSIM is pre-configured to work instantly:

Insert SIM → Power on charger → Connect automatically
No manual settings
No installer training required
No delays in commissioning

For manufacturers, this significantly reduces customer support tickets and accelerates deployment timelines.

6. Scalable, OEM-Friendly Commercial Model

Our simple commercial structure allows OEMs to plan long-term production lines with confidence:

£2.50 per SIM
500MB aggregated data pool
No long contracts
Cancel anytime with 30-day notice
Zero hidden charges
No per-device activation fees

Manufacturers can bundle connectivity into their hardware without complexity.

7. Compliance, Reporting & Regulatory Alignment

As regulations tighten on sustainability and charging performance, IoT connectivity helps manufacturers comply with:

OCPP reporting
Energy consumption monitoring
CO₂ reduction documentation
Safety and performance audits

GleeSIM supports complete data visibility across every deployed charger.
