About eUICC SIM profiles

An eUICC SIM profile acts as a virtual SIM within the SIM container. Downloading and enabling a new profile means that an IoT device can switch to a different network operator without the need to physically change the SIM.

Eseye provides the Connectivity Management Platform (CMP) to manage loading, switching, and deleting profiles.

Each profile contains:

  • An ICCID to uniquely identify the profile
  • One or more IMSIs, depending on the profile type, to identify the network subscriber
  • Operator subscription data, including authentication credentials
  • Policy rules

The content and structure of profiles is standardised to ensure interoperability between all network. Each IMSI account is provided by the mobile network to which it connects.

The number of profiles that can be stored on an eUICC is limited only by the memory available and the size of each network operator’s profile. For information about memory capacity, see the relevant Datasheets.

You can only enable one profile at any time. The profile currently in use (enabled) is called the active profile.

For information about how eUICC IMSIs are managed OTA, see Remote SIM Provisioning overview.

eUICC SIMs support the following profile types:

You can flag the bootstrap or an operational profile as the fall-back (see below).

About fall-back and roll-back

As a safe-guard against failed connections, eUICC SIMs use fall-back and roll-back.
