Author profile

Peter Green has spent more than twenty years working in cellular connectivity, M2M, and IoT infrastructure. He got into the industry in the late nineties – back when M2M meant a serial port and a prayer – and has been building things in the space ever since.

His background spans cellular routers, SIM management, signal diagnostics, and network infrastructure. He has worked with major IoT connectivity standards and watched the industry evolve from basic M2M through 4G LTE to the current shift toward eSIM, eUICC, and 5G RedCap.

He writes about what he knows: SIM technology, eSIM and eUICC standards, cellular router configuration, and the gap between how connectivity products are marketed and how they actually perform in the field.
