GleeSIM provides specialised 5G mobile broadband IoT SIMs for EV charging infrastructure, enabling reliable connectivity for public, commercial, and residential charging points across the UK and Europe. Designed for mission-critical EV environments, GleeSIM ensure seamless communication between EV chargers, mobile applications, and backend management platforms.

Modern EV charging stations depend on stable internet connectivity to support user authentication, payment processing, session management, remote monitoring, firmware updates, and energy usage reporting. GleeSIM’s multi-network IoT SIMs provide continuous uptime by dynamically connecting to the strongest available network, eliminating the risks associated with single-network SIMs and weak WiFi or fixed-line connections.

GleeSIM supports 4G, 5G, and 5G+ connectivity, ensuring low latency and high performance even in challenging environments such as underground car parks, indoor installations, and rural locations. Each deployment is backed by a pre-installation coverage assessment, ensuring optimal signal strength and reliability before rollout.

For enhanced security and control, GleeSIM offers private APN, VPN integration, and IP whitelisting, enabling secure communication between EV chargers and OCPP (Open Charge Point Protocol) platforms. This ensures safe handling of user data, payment transactions, and operational commands in compliance with GDPR requirements.

GleeSIM SIMs are fully compatible with leading hardware providers such as Teltonika, Peplink, TP-Link, and Four-Faith routers, and integrate seamlessly with EV charger systems and embedded modules. This flexibility allows EV infrastructure providers to deploy scalable connectivity solutions across diverse environments.

Real-world deployments across the UK have demonstrated significant operational improvements, including 49% uptime improvement, 40% reduction in downtime, and 38% increase in charger utilisation. These results highlight the importance of reliable IoT connectivity in maintaining service availability and enhancing customer experience.

One of the primary challenges in EV charging infrastructure is maintaining consistent uptime without manual intervention. Many operators still rely on physical inspections due to unreliable connectivity. GleeSIM eliminates this inefficiency by enabling real-time remote monitoring and control, allowing operators to detect faults, optimise performance, and reduce operational costs.

Compared to fixed-line broadband, mobile broadband IoT SIMs offer greater flexibility and cost efficiency. Operators can remotely access routers, monitor performance, and manage configurations without dependency on local infrastructure, resulting in improved scalability and reduced deployment costs.

As EV adoption accelerates across the UK, with charging infrastructure expected to grow by over 50% in the next 2–3 years, the demand for reliable connectivity will become increasingly critical. GleeSIM positions itself as a trusted EV connectivity partner, offering flexible commercial models, including short-term contracts starting from 3 months, pilot deployments, and scalable enterprise solutions.

EV infrastructure providers, local councils, and fleet operators can engage with GleeSIM through a structured process including consultation, coverage assessment, and trial deployment, ensuring a tailored connectivity solution aligned with operational requirements.
