Key Terms

The following table defines the key terms used in the documentation:

APN (Access Point Name)

An APN functions as the entry point between a cellular network and another computer network, such as a private corporate network.

To establish a data connection with a network operator, a mobile device must be configured with an APN. The network operator may use the APN to determine the type of data connection that should be created, for example, the APN may be used to define what security methods to use for the connection.

The Connectivity Management APN is wholly owned and managed by us and it is deployed on each network we partner with.

This allows seamless use of any SIM that Connectivity Management provides on any partner network.

Bootstrap Profile

A bootstrap profile provides an eUICC SIM with an initial method for obtaining network connectivity when the device it is inserted in is first switched on.

A bootstrap profile is a preconfigured base profile that cannot be removed from an eUICC SIM.

The bootstrap profile's primary function is to download operational profiles, which can then be provisioned on the eUICC SIM. 

CDR (Call Data Record)

A CDR is a record of the data associated with a communications transaction occurring over a telecommunications network. Communications events may include telephone calls, text messages or packet data transmissions.

A CDR can contain information such as the date and time at which the transaction occurred, the transaction's duration and the source and destination numbers involved in the transaction.

Typically, CDRs are used to calculate billing information.


(Embedded Universal Integrated Circuit Card)

The term eUICC relates to SIM cards and cellular connectivity.

An eUICC SIM is the physical SIM that eSIM profiles are provisioned on. An eUICC is a removable or non-removable SIM which enables remote and/or local management of profiles in a secure way.

Remote SIM Provisioning and eUICC SIMs allow a network subscriber to remotely provision SIM profiles over the air, without having to change the device's physical SIM card.

eSIM profile

This term relates to the virtual SIM profiles that can be provisioned on eUICC SIMs over the air using Remote SIM Provisioning.

GSM (Global System for Mobile Communication)

GSM is a standard, developed by the European Telecommunications Standards Institute.

The standard relates to the protocols associated with 2G digital cellular networks that are used by cellular devices, such as mobile phones.

IoT (Internet of Things)

The Internet of Things is a network of devices, appliances and other objects that are embedded with network connectivity, software and sensors to enable the collection and transmission of data via the Internet.

LPWAN (Low-Power Wide-Area Network)A LPWAN is a type of wireless network, designed to facilitate low bitrate communications between low-power devices, such as battery operated sensors.
M2M (Machine to Machine)

Machine-to machine communication is any form of direct communication between devices over any communication channel.

M2M communication occurring over the IoT typically enables a sensor or meter to communicate data to a software application for recording or decision making purposes.

MVNO (Mobile Virtual Network Operator)

An MVNO provides wireless communications services to customers over a wireless network infrastructure.

An MVNO does not own the wireless network infrastructure that it uses to provide its services.

Typically, an MVNO purchases bulk access to a mobile network operator’s network at a wholesale rate and resells it to their own customers.

Operational Profile

The term operational profile relates to eSIM profiles.

An operational profile represents a subscription agreement with a particular network operator. When an operational profile is downloaded and enabled on an eUICC SIM it grants the subscriber with access to the operator's network. An eUICC SIM can contain multiple operational profiles, however, only one can be enabled at any given time. Operational profiles can be ordered using the Connectivity Management platform.

PaaS (Platform as a Service)

This is a type of cloud computing service in which a platform for developing and managing a custom application is delivered to customers by means of the Internet.

Obtaining a PaaS allows customers to develop and manage a custom application without having to manage the complex infrastructure associated with the development effort.

RSP (Remote SIM Provisioning)

Remote SIM Provisioning provides users with the ability to provision eSIM profiles over the air, without having to change the SIM card that's inserted inside of a device.

The term Remote SIM Provisioning refers to the entire process of provisioning an eSIM profile on an eUICC SIM. These processes include downloading, installing, enabling and disabling profiles on eUICC SIMs.
