IoT SIM Card disrupter transits 70m MB in 2025 on track for 100m+ in 2026

KeySIM, the UK-based IoT SIM connectivity provider, has reported significant growth across its network with total data throughput nearly doubling year-on-year.

The company processed 36.5 million MB in 2024 increasing to 71.5 million MB in 2025 — a 49% rise driven by growing demand for resilient, multi-network IoT SIM Cards. 

This growth is being fueled by UK organisations migrating major connectivity contracts to KeySIM as they seek greater control, security, and performance from their IoT deployments.

Built on a Tele2 core network and enhanced through private breakout across multiple UK data centers KeySIM delivers high-performance IoT services including private APNs, VPN connectivity and fixed IP addressing.

The business supports over 500 UK enterprises across sectors including security, healthcare, retail, and infrastructure and remains firmly on track to exceed 100 million MB of data throughput in 2026.

KeySIM is led by co-founder Graham Robinson who brings over 20 years’ experience in IoT, including the development of a SIM-powered lone worker solution — experience that has directly shaped the company’s network architecture and service offering.

Graham Robinson, Co-Founder of KeySIM, said:

“This level of growth reflects a broader shift in how organisations approach IoT connectivity, with increasing emphasis on security, control, and performance.

KeySIM’s architecture has been designed to meet these requirements, and current growth levels indicate strong ongoing demand.”
