The rollout of Electric Vehicle (EV) infrastructure is accelerating rapidly. However, a public EV charger is a highly complex IoT device. It requires a continuous, robust internet connection to process contactless payments, communicate with the user’s smartphone app, and perform real-time load balancing with the national grid.
If the charger loses signal, the driver is stranded. Therefore, standard consumer networks are unacceptable; operators must use industrial SIM cards for EV chargers.
The Challenge of Charger Placement
EV chargers are often installed in hostile RF environments:
- Underground concrete car parks.
- Remote rural motorway service stations.
- Dense urban street corners suffering from massive network congestion.
A single-network SIM (e.g., EE) is statistically guaranteed to fail in a percentage of these diverse locations, leading to “Out of Order” signs and furious drivers.
Failsafe Multi-Network Infrastructure
Charge Point Operators (CPOs) secure their revenue and reputation by utilizing Anywhere SIM’s unsteered multi-network technology.
- Universal Uptime: Our SIMs grant the charger access to all four major UK networks. If the charger is in an underground car park, the SIM automatically scans for the specific low-frequency network that manages to penetrate the concrete, ensuring the payment terminal comes online.
- Automatic Congestion Bypass: If a charger is located at a busy stadium, the local mast may become congested, causing payment timeouts. Our unsteered SIM detects the packet loss and dynamically switches the charger to a less congested competitor’s mast, ensuring the transaction processes instantly.
- Secure OCPP Routing: EV chargers transmit sensitive grid and payment data via the OCPP protocol. We provide secure Private APNs and VPN routing to protect this critical infrastructure from cyber threats.
