Meaning
Connectivity profile management allows a device to change its primary network identity to access local rates or better coverage while roaming. The multi-imsi switching process involves selecting a different international mobile subscriber identity from a list stored on the sim card. It enables global deployments using a single hardware stock keeping unit.
Identity Selection
Logic within the modem or an applet on the sim decides which profile is best for the current location. During multi-imsi switching, the device evaluates available networks to find one that matches the programmed list of preferred partners.
Profile Transition
Re-registration on a new network is required whenever a different identity is activated. Successful multi-imsi switching involves a brief disconnection as the radio resets to apply the credentials and security keys for the new provider.
Network Availability
Access to localized service prevents the high costs often associated with permanent roaming. Implementing multi-imsi switching provides a fallback option if the primary carrier has poor signal quality in a specific region. This capability is essential for tracking assets that move across national borders where different operators hold the spectrum licenses.
Roaming agreements can be updated over the air to add new identities to the device without needing physical access to the hardware.
