UK-based IoT connectivity provider KeySIM has introduced a new pricing structure aimed at businesses deploying more than 100 Internet of Things (IoT) SIM cards, offering a flexible pay-as-you-go alternative to traditional connectivity contracts.
The new tariffs are designed to help organisations reduce unnecessary costs while providing reliable multi-network connectivity for everything from CCTV systems and industrial automation to environmental monitoring and remote networking.
Under the new commercial offering, UK businesses can access multi-network IoT SIM cards for a monthly rental of just £1.50 per SIM. Mobile data is charged at £0.0025 per megabyte on a true pay-as-you-go basis, ensuring customers only pay for the data they actually consume.
Businesses requiring connectivity across both the UK and Europe can opt for KeySIM's UK and European service, priced at £3.25 per SIM per month, with European data charged at £0.008 per megabyte.
Unlike many traditional IoT connectivity packages, KeySIM imposes no minimum contract terms, allowing customers to cancel SIMs whenever required. UK voice calls and SMS messages are both charged at £0.05 per minute or message.
A key feature of the service is its multi-network capability. KeySIM's IoT SIM cards connect to all four major UK mobile networks, Vodafone, O2, EE and Three, helping businesses maintain connectivity by automatically selecting the strongest available signal.
The company says its unsteered SIM technology provides an important advantage over many conventional IoT SIMs, which often prioritise a preferred network and can experience unnecessary disconnections. For organisations that require greater control, customers also have the option to manually steer SIMs to a preferred network during planned maintenance, local outages or service disruptions.
KeySIM also offers optional fixed IP addresses, enabling secure remote access to CCTV installations, telemetry systems, industrial equipment, routers and other connected devices.
Founder Graham Robinson said the new pricing reflects the company's continued growth and commitment to transparent, technically robust IoT connectivity.
He told That's Business: "The launch of these new tariffs comes at an exciting time for KeySIM," he said. "The business now supports more than 500 customers and, during June 2026 alone, transited more than 10 million megabytes of data across our platform. These milestones reinforce our commitment to delivering transparent, flexible and technically robust IoT SIM connectivity for businesses throughout the UK and Europe."
The financial benefits of the model are already being realised by customers. Irish security specialist CSC Security Consultants switched from a pooled data arrangement to KeySIM in 2022 after discovering that around 27 per cent of the mobile data it had been purchasing was never actually used.
Managing Director Declan Cassin said the move had significantly reduced unnecessary expenditure while also delivering excellent technical support. He added that KeySIM successfully integrated the firm's CCTV connectivity into its RE Monitoring Centre, providing secure monitoring capabilities for its camera systems.
As businesses continue to expand their use of connected devices across multiple sectors, demand for flexible, usage-based connectivity is increasing rapidly. KeySIM's latest pricing is aimed squarely at organisations looking to scale their IoT deployments without being tied into long-term contracts or paying for unused data.
