An IMSI is usually presented as a 15 digit number, but can be shorter (not longer).


Internet of Everything

The Internet of Everything is the connection between people, things, data and processes combined into a common interrelated system, the aim of which is to improve experiences and make smarter decisions. Today, everything can be connected with everything, creating a new distributed ecosystem that goes beyond the familiar IoT (Internet of Things) concept. Any object can be outfitted with digital features and connected to the common network of other objects, people and processes in order to generate valuable information, exchange it and facilitate relevant decision-making.

Internet of Things

The IoT refers to a network of electronic devices also called objects (such as sensors and actuators) that collect some kind of data autonomously based on physical World events from sensors that are attached to them. These objects are connected to the Internet so that they can send the data they collect from sensors to a larger, more powerful processor or server, becoming active participants in various public, commercial, scientific, and personal processes.

IoT module

An IoT module is a small device embedded in objects, things and machines that is responsible for connecting virtually anything to wireless networks to send and receive data.

Mobile Country Code / Mobile Network Code

The Mobile Country Code (MCC) and Mobile Network Code (MNC) fields together specify which carrier you are using. Each carrier in the world has their own unique MCC and MNC value pair.

Mobile / Cellular Network

A Mobile or Cellular network is a radio network distributed over land areas called cells, each served by at least one fixed-location transceiver, known as a cell site or base station. Each cell within a cellular network uses a different set of frequencies from neighboring cells, to avoid interference and provide guaranteed bandwidth within each cell.


Mobile Originated SMS

A Mobile Originated message (SMS MO) is a mobile message routed from an end user’s mobile device and delivered to a mobile device or an application. In the latter case, incoming messages can be seen over a specialized web interface, which usually offers additional reporting and analytics abilities. Incoming messages can be forwarded to SMPP, HTTP push or pull, or email. Also, they can trigger further actions – an automatic reply, opening of a support ticket etc.
