In the UK, business connectivity is shifting from simple mobile plans to mission‑critical IoT and M2M deployments that must stay online 24/7. From EV chargers and CCTV to telemetry, retail, construction, and logistics, companies now need industrial‑grade SIMs, multi‑network coverage, fixed and private IP options, and secure VPN connectivity as standard. GleeSIM is built for this new reality, combining enterprise‑class industrial/M2M SIMs with flexible tariffs and strong UK‑wide network options.

Why industrial / M2M SIMs matter

Industrial and M2M SIMs are engineered to survive harsh environments, high usage, and long lifecycles where a normal consumer SIM would fail. They support devices that are deployed once and expected to run reliably for years, with remote management, status monitoring, and secure communication back to core business systems. For UK businesses investing in EV charging, smart buildings, transport, and automation, industrial‑grade M2M SIMs are now a core infrastructure choice rather than a “nice to have”.

GleeSIM’s core strengths for UK businesses

GleeSIM already offers a powerful mix of features tailored to business and IoT needs in the UK.

UK businesses are deploying more connected devices than ever before, from EV chargers and energy meters to security systems, retail terminals, and industrial automation. These machines cannot rely on consumer SIMs or best‑effort connectivity; they need industrial‑grade M2M SIM cards with guaranteed coverage, secure IP options, and easy management at scale.

GleeSIM specialises in industrial and M2M SIM solutions that keep your critical infrastructure online, secure, and controllable from anywhere. With 5G‑ready, multi‑network, and fixed‑IP options designed specifically for UK deployments, GleeSIM helps organisations modernise connectivity without adding complexity.

Multi‑network industrial SIMs for maximum uptime

When a single network fails, your devices cannot. GleeSIM offers multi‑network IoT and M2M SIMs that can connect to multiple UK mobile operators, increasing resilience for mission‑critical sites like EV charging hubs, retail estates, and remote assets.

For UK businesses, this means fewer truck rolls, less downtime, and better customer experience—whether it is a driver plugging into an EV charger or a customer tapping their card on a payment terminal. Multi‑network access, pooled data options, and flexible contracts make it simple to scale from a small proof of concept to a full national rollout.

Fixed IP, private APN, and VPN‑ready connectivity

Many industrial deployments need predictable addressing and secure, direct access to devices. GleeSIM delivers fixed IP 4G/5G SIMs, private APN options, and architectures that integrate cleanly with VPNs and central firewalls, ideal for CCTV, remote monitoring, and SCADA‑style environments.

By isolating critical traffic from the public internet and giving IT teams full control over routing and policies, GleeSIM helps UK organisations meet security and compliance requirements while keeping management simple. This is especially important for sectors like utilities, transport, and financial services, where connectivity is part of regulated infrastructure.

Designed for EV charging, smart sites, and beyond

GleeSIM explicitly supports high‑growth use cases such as EV charging networks, where each charger needs reliable mobile data for authorisation, billing, firmware updates, and real‑time telemetry. Non‑steered roaming, data pooling, and industrial‑grade SIMs make it easy for charger manufacturers and operators to standardise on a single connectivity partner across the UK.

The same platform also supports construction sites, temporary events, retail chains, and logistics fleets, giving IT teams one set of tools and tariffs to manage thousands of SIMs across diverse environments. This reduces operational overhead and accelerates digital transformation projects that depend on always‑on connectivity.
