  • 3GPP Non-terrestrial Network (NTN)  Satellite connectivity based on 3rd Generation Partnership Project (3GPP) specifications to create a non-terrestrial network (NTN) ecosystem, enabling connectivity between terrestrial systems and satellite systems on the same mobile platform. NTN enables a smooth transition between cellular and satellite connectivity for IoT devices needing constant cellular connectivity.
  • 5G Internet of Things 5G is the fifth-generation 95G) wireless technology, which offers low latency and high speed connectivity reducing the time for messages to travel over the network and increasing reliability. It offers new features for IoT including increased bandwidth, supporting many more devices for massive IoT deployments which benefits Low Power Wide Area (LPWA) deployments with much longer battery life.
  • Blob (iSIM) The digital bundle, that is the output from SAS-UP iSIM generation, which is loaded into a silicon chip's Secure Enclave (iTRE) to create an iSIM.
  • Cellular IoT Cellular IoT connectivity is the transmission of data packets over the air using a wireless spectrum to mobile network towers. The towers connect asset-tracking applications, smart meters, smart wearables, healthcare monitoring, security systems and many other devices to the internet via 4G, 5G, LTE Cat. 0, LTE Cat M, 4G LTE, LTE Advanced and 5G.
  • Consumer solution for remote SIM provisioning The GSMA specification for managing profiles on consumer connected devices (eg. mobile phones and wearables).
  • eDRX (Discontinuous Reception) Power power-saving feature provided by LTE networks that allows them to stop listening for data and sleep for 1-2 seconds at a time.
  • eSIM (embedded SIM) A SIM capable of supporting remote provisioning. Also, a physical non-removable SIM that is soldered into a device. The term is used interchangeably with eUICC.
  • eSIM for IoT devices (SGP.32)  The eIM (eSIM IoT Remote Manager) enhances the eSIM capabilities by initiating operator profile changes remotely streamlining and optimizing the management of mass deployments of eSIM-enabled devices. The eIM can be configured at the eUICC manufacturing and communicates with any IoT device and any SM-DP+ plus the IoT profile assistant (IPA) allows more convenient local profile switching.
  • eUICC (embedded Universal Integrated Circuit Card) A SIM capable of supporting remote provisioning. The term is used interchangeably with eSIM.
  • EUM (eUICC manufacturer) An entity which provides eUICC personalization service. It may or may not engage in physical card manufacturing.
  • FF (Form Factor) The size and shape of a UICC. Such as: 2FF, 3FF, 4FF, MFF2 (solderable machine-to-machine form factor).
  • IoT SAFE (IoT SIM Applet For Secure End-to-End Communication) An interoperable, GSMA standard that uses the SIM as a miniature crypto-safe inside the device to securely establish a datagram transport layer security (D)TLS session with a corresponding application cloud or server. It provides a common application program interface (API) for the SIM  to be used as a root of trust by IoT devices to ensure data is transmitted securely to and from approved devices only.
  • iSIM (integrated SIM) or iUICC (integrated Universal Integrated Circuit Card) eUICC software which runs in a dedicated secure enclave, alongside the processor and modem, on a purpose-built SoC.
  • Just-in-Time Provisioning In-factory secure personalization with any MNO connectivity of choice enabling extensive device testing and out-of-box connectivity.
  • LPA (Local Profile Assistant) The functionality in the device’s main operating system which provides services, such as profile download or profile management to the eUICC.
  • M2M (Machine-to-Machine) solution for remote SIM provisioning The GSMA specification for managing profiles on unattended, autonomous IoT devices, without any end-user interaction.
  • Multi-IMSI (Multiple International Mobile Subscriber Identities) Multi-IMSI is a unique set of digits that forms an important part of a Subscriber Identity Module (SIM) profile that lets Mobile Network Operators authenticate their subscribers for access to their network and other roaming agreement networks.
  • Personalization Applying a set of software data to an eUICC that enables it to function and makes it unique. This can include an operating system, applications, profiles and security configurations.
  • Profile (also, operator profile) A combination of data and applications that enables access to a cellular network and influences some aspects of the device behavior on the cellular network.
  • PSM (Power saving mode) Power saving mode for smart meters when switching between local roaming connections.
  • RSP (Remote SIM Provisioning) Secure and remote (over the air) management of network operator profiles on an eSIM or iSIM.
  • SAS-SM (Security Accreditation Scheme - Subscription Management) The security auditing and accreditation scheme for providers of eUICC subscription management services.
  • SAS-UP (Security Accreditation Scheme - UICC Production) The security auditing of the sites - including their organization, processes and people - where profile generation, UICC and eUICC production and personalization is conducted.

  • SIM OTA (SIM over the air) Secure mechanism for updating the content of a SIM profile.
  • SIM (Subscriber Identity Module) The secure element that stores security data enabling network access. Colloquially, SIM is often used to refer to the removable physical SIM card containing a UICC with a single profile.
  • SM-DP (Subscription Manager Data Preparation) The server-side platform of the M2M remote SIM provisioning architecture that acts on behalf of the network operator to securely store profiles in readiness for an allocation and download request. Upon establishing a secure session with the target eUICC, it executes their download and installation.
  • SM-DP+ (Subscription Manager Data Preparation Plus)  The central server-side platform of the consumer remote SIM provisioning architecture that securely stores profiles, makes them available for and negotiates their secure download to the target eUICC via the device LPA.
  • SM-DS (Subscription Management Root-Discovery Service)  The universally available platform within the consumer remote SIM provisioning architecture that may be used to inform an eUICC that a profile has been made available for download and on which SM-DP+.
