The Industrial eSIM Revolution: A Conversation with Pelion’s Alan Tait

As the Internet of Things moves from early trials to large industrial rollouts, the less visible pieces of connectivity start to matter more than the gadgets on the factory floor. At MWC Barcelona 2026, Pelion’s Alan Tait frames industrial eSIM as part of this quiet infrastructure shift: companies now need connectivity they can manage at scale across many countries, networks, and device lifecycles, not just a SIM card in a box.

The focus is on technical architecture rather than hype. Industrial eSIM promises remote provisioning, simpler global coverage, and more control over how devices connect as networks and suppliers change. For operators of large fleets of sensors, machines, or vehicles, the question is less "what is eSIM" and more "does this setup make it cheaper and easier to keep thousands of devices online for years". That is where Tait positions Pelion’s role in the industrial eSIM landscape.
