What is a profile?
An operator profile is a digital package stored on a SIM, eUICC, or eSIM that defines how a device connects to a mobile network. It contains the network credentials, configurations, and rules required for secure access, authentication, and service behaviour.
In essence, it is a “network identity” that determines which mobile network operator (MNO) the device communicates with, as well as how it behaves in that network (e.g. roaming, data settings, access privileges).
What it Includes
Typical components of a profile are:
- ICCID, IMSI and Ki values (unique identifiers and cryptographic keys)
- Network parameters and configurations (e.g. APN, PLMN settings)
- Authentication credentials that allow the device to prove itself to the network
- Policy or service rules, such as roaming permissions, preferred networks, and priority behaviour
Because the profile holds critical credentials and logic, it must be securely provisioned and managed — often using Remote SIM Provisioning (RSP). For example, Kigen’s RSP services are GSMA SAS-accredited and enable secure loading and management of operator profiles in eSIM devices.
Why Operator Profiles Are Important in IoT / eSIM
- Remote provisioning & flexibility: With eSIM / eUICC, profiles can be downloaded, switched, or updated remotely without physical SIM swaps, enabling devices to adapt to new networks or operators over time.
- Reduced SKUs & logistics: Devices can ship with a blank or bootstrap profile and later receive the proper operator profile in the field, simplifying inventory and global deployment.
- Interoperability & scalability: Standardized profiles allow devices to work across multiple networks and geographies. Kigen’s eSIM OS supports multiple operator profiles, enabling global connectivity.
- Security & lifecycle management: Profiles are managed securely, often under GSMA’s security frameworks, to prevent tampering or unauthorized access.
