Why Connect with Millbeck
Millbeck specialises in the cellular hardware and SIMs that sit between an industrial device and the network it depends on. The kind of work where the spec decisions made on day one decide whether the deployment is still online in year five.
Specialist
Knowledge
The hardware, SIMs, antennas, and configuration that go into a cellular deployment are specific work. We have spent 25 years specifying it correctly the first time, on projects from single-site failover to multi-thousand-device estates.
Personal
Service
When you call, you reach the people who configure the hardware and manage the SIM platforms we sell. Every customer works with a named account manager who handles the project from hardware selection through to ongoing SIM management.
