If you are buying an eSIM-enabled smartphone, SGP.22 is probably exactly what you need. If you are deploying 10,000 electricity meters, environmental sensors, vehicle trackers, payment terminals or industrial routers, it may be the wrong architecture entirely. That … Read more
We went looking for the ultimate unlimited, public-IP IoT SIM: uncapped data, a real IPv4, multi-network, 5G, no contract, no fair-use trap. Did it exist? Almost. Here is the one box nobody can tick, and the architecture that … Read more
For years the cellular router in an industrial cabinet did one job. It took data from a device and pushed it up a mobile network. The router was a pipe, and a pipe was enough. That assumption is … Read more
On 5 September 2026, Poland’s national CERT confirmed something that should focus the mind of anyone running a router at the edge of a network: attackers are taking full administrative control of internet-exposed MikroTik devices without any username, … Read more
For several years, the Teltonika RUTX range has been one of the most recognisable families of industrial routers used in IoT, M2M and remote connectivity projects. These were not simply faster versions of Teltonika’s smaller RUT routers. RUTX … Read more
August 2026 is the month SGP.32 stopped being a specification people discussed and became a product people buy. That is the honest headline, and it carries an equally honest asterisk: the SIMs, the orchestration platforms and the first … Read more
Connectivity The Router Isn’t the Story Anymore: Robustel, Kigen and the Plastic eSIM For a couple of years, “eSIM router” meant new silicon and a new SKU. Robustel’s move with Kigen argues otherwise: the shortest route to an … Read more
Cellular IoT has spent two decades tripping over the same small square of plastic. The device engineering got extraordinary: modules shrank, power budgets tightened, and firmware learned to sleep for months and wake on a schedule measured in … Read more
An IoT system installed today may still be monitoring a pumping station, controlling a building, reporting from a railway asset or protecting an electricity network in 2041. During those fifteen years, mobile networks will change, cryptographic standards will … Read more
