KeySIM Surpasses 10,000 Connected IoT SIMs as Businesses Switch to Multi-Network PAYG Connectivity

KeySIM, a UK-based provider of multi-network IoT SIM cards, today announced it has surpassed 10,000 active IoT connections across more than 500 customers, marking a major milestone in the company’s rapid growth.

The achievement reflects a growing shift among businesses away from single-network, contract-based models. Organisations are increasingly choosing KeySIM’s multi-network, pay-as-you-go (PAYG) solution to achieve stronger connectivity, greater flexibility, and significant cost savings.

KeySIM is also the first IoT SIM provider to develop a remotely steerable SIM card, allowing users to toggle mobile networks remotely from the KeySIM management platform. This innovation gives customers unprecedented control over connectivity — ensuring uptime, optimising performance, and simplifying large-scale IoT deployments.

In addition, KeySIM enables customers to remotely access the private IP addresses assigned to their SIM cards, removing the need to expose devices via insecure public fixed IPs. By providing secure, managed access to devices over private addressing, KeySIM reduces the attack surface for IoT estates, simplifies network architecture, and eliminates costly public IP provisioning.

“Reaching 10,000 connected SIMs is an important milestone for KeySIM and a clear sign that the market is ready for a more agile approach to IoT connectivity,” said Graham Robinson, Founder of KeySIM. “Our remotely steerable SIM technology — combined with secure access to private IPs — gives businesses real control: they can switch networks remotely, securely reach devices without exposing them to the public internet, and only pay for what they use.”

KeySIM’s technology is already trusted by organisations such as FATFACE and the North Wales Mountain Rescue Team, supporting applications ranging from retail connectivity to mission-critical emergency communications.

KeySIM’s SIM cards provide reliable connectivity across the UK and internationally. The company’s PAYG model provides customers with no minimum spend, no long-term contracts, and real-time visibility through a self-service online dashboard.

KeySIM serves clients across a wide range of sectors — including security, renewable energy, transport, logistics, and retail — supporting applications such as remote monitoring, smart metering, and mobile data connectivity.

As IoT adoption accelerates globally, KeySIM’s flexible and transparent approach offers a future-proof alternative to traditional telecom contracts, empowering organisations to scale efficiently and cost-effectively.
