What is eSIM eSIM describes a remotely provisioned SIM ecosystem using an eUICC to securely install and manage operator profiles. An eUICC can be removable, soldered into equipment or integrated into a suitable secure hardware element. It is not simply a physical SIM replaced by software. Changing the subscription without swapping cards requires compatible hardware, firmware, provisioning services and operator permission. Core characteristics of eSIM include: Form factor: Rem

A remote pump can send a temperature value to a maintenance dashboard without giving the dashboard direct access to its PLC. MQTT is one way to move that value: a client publishes a message to a broker, and authorized subscribers receive messages on matching topics. The protocol does not define what a pump value means, read a Modbus register on its own or make a cellular link reliable. Before choosing MQTT settings, identify the source of each data point, the publisher, the b
