About
Most content about IoT connectivity falls into one of two categories.
Vendor marketing dressed up as education. Or academic content that is technically correct and completely useless in production.
Neither helps the people who actually have to make decisions. The engineer choosing a SIM architecture for a 50,000-unit rollout. The product manager trying to understand why devices keep dropping in Germany. The founder about to sign a three-year connectivity contract without knowing what questions to ask.
This site exists because none of that content was written for them.
Who writes this
I'm David. I spent several years at Telit Cinterion, one of the largest IoT module and SIM vendors in the world, working on SIM, eSIM, modules, and large-scale global deployments. Now I work in IoT connectivity in Europe, focused on helping companies connect, run, and scale devices in the field.
I have been in the technical calls. The failed POCs. The coverage disputes. The contract negotiations where nobody asked the right questions until it was too late.
I have seen what breaks, why it breaks, and what a solid deployment looks like versus one that quietly fails 18 months after everyone who built it has moved on.
That experience is what this site is built on.
What you will find here
Practical guides written for real scenarios, not theoretical ones.
Every sector that runs on cellular has its own constraints, priorities, and failure modes. Fleet telematics is not the same problem as smart metering. Security alarms have different uptime requirements than POS terminals. Healthcare devices operate under compliance pressures that asset trackers do not.
The guides here are written with that context in mind. Coverage across:
- Fleet and telematics
- Security and alarms
- Smart metering
- POS and payments
- Asset tracking
- Healthcare
- Smart buildings
- Smart lighting
Alongside a full technical reference covering SIM types, eSIM standards (SGP.22 and SGP.32), roaming behaviour, APN architecture, CMP platforms, and how to evaluate and switch connectivity providers.
No paywalls. No vendor bias. No fluff.
