The right UK network for every IoT device

UK IoT connectivity is not one-size-fits-all. Coverage varies between the UK's networks, so the right choice depends on where your devices need to work, not just what they need to do.

All four UK networks are moving through their 2G and 3G network sunset, with 3G already switched off and 2G closing by 2033. NB-IoT and LTE-M cover low-power devices, Cat-1 BIS brings cost-effective mid-bandwidth connectivity for use cases that need more than NB-IoT or LTE-M offer, and 4G and 5G support demanding applications. Together, they give every deployment the right fit, not just an exit route from ageing networks. Choose the network that's right for your device and its UK network coverage needs, not just the one you've always used

Wireless Logic connects IoT deployments across multiple UK mobile networks, reducing reliance on any single carrier. Multi-network SIMs help improve coverage and resilience, while centralised management makes it easier to control, monitor and scale large device estates across the UK.

Wireless Logic's artificial intelligence-powered threat detection operates within the mobile core. It monitors IoT communications in near real time, identifying malware, botnet activity, suspicious connections and unusual behaviour across large UK IoT estates, with over one million connections monitored.

SIMPro provides a single platform to manage large UK IoT estates across multiple mobile networks. Provision SIMs, diagnose device status, create policies, analyse performance and perform bulk actions from one place, with near-complete API and portal parity enabling enterprise customers to automate management at scale.

SGP.32 factory bootstrap profiles let devices connect from the point of manufacture, with operational profiles activated over the air at market entry. Wireless Logic has already deployed more than 2 million eSIM profiles this way, backed by a contractual Right to Exit with no carrier lock-in.

What is the best IoT SIM card for the UK?

The best IoT SIM for the UK has security built into the network core rather than bolted on afterwards, so resilience doesn't depend on any single network staying up. It's managed from one console instead of multiple carrier portals, with a single eSIM covering every device on the estate.

That single-eSIM approach also keeps costs down: a Wireless Logic IoT SIM can scale from a small UK pilot to thousands of devices nationwide without changing hardware. And underneath it all, it's multi-network by design, so coverage never relies on just one operator.

Healthcare & medical devices:
Never miss a vital sign

From remote patient monitoring to virtual wards, healthcare devices can't afford to drop connection. Wireless Logic keeps them online across hospitals, care settings and patients' homes, with full visibility if a device needs attention.

IoT for healthcare

Security and surveillance:
Never miss a moment

CCTV, access control, alarms and lone worker devices are increasingly moving from legacy PSTN lines to cellular. Wireless Logic SIMs fail over automatically between networks, so one outage doesn't leave a site unmonitored.

IoT for security sector

Transport & logistics:
Never lose track

Vehicles and assets move between coverage areas all day, so fleet tracking, telematics and safety systems need a connection that keeps up. Automatic network failover keeps data flowing, wherever a vehicle is on the road.
