GSMA Official Document 12FAST.13 – Embedded SIM Remote Provisioning Architecture published in December 2013 provides a technical specification to enable the remote provisioning and management of Embedded SIMs to allow the “over the air” provisioning of an initial operator subscription and the subsequent change of subscription from one operator to another. The technical specification includes technical use cases for the provisioning of the Embedded Universal Integrated Circuit Card. The following are worked examples of business use cases for M2M provisioning.
Use Case #2: Corporate Customer Fleet Management Change MNO
Pamela wishes to upgrade the telematics capabilities of City Deliveries’ existing vehicles. The existing vehicles are after-market fitted with an M2M device including an eUICC embedded SIM provisioned to MNO B.
Pamela wishes to migrate these subscriptions from MNO B to MNO A to take advantage of dedicated telematics software provided by MNO A.
Use Case Flow:
- City Deliveries enters into a subscription with MNO A for the after-market devices
- MNO A knows the eUICC-IDs for the devices and the ID of the registered SM-SR
- The eUICC is registered with a common SM-SR between MNO A and MNO B
- MNO A initiates provisioning of the devices
- MNO A initiates the Profile Download and Installation which results in an ISD-P created in the eUICC for the MNO, containing a Profile in disabled or enabled state. The SM-SR has updated the EIS for this eUICC accordingly.
- MNO A activates the subscription and all the devices are operative with MNO A
- MNO B initiates de-provisioning for all the eUIDDs
- MNO A’s profile is cleared from all devices
Alternative Flow (Step 3): The eUICC is registered with a different SM-SR
- Note: To allow remote access to the eUICC the eUICC Manufacturer (EUM) registers the eUICC at a selected Subscription Manager Secure Routing (SM- SR). This means that related information which is relevant throughout its further lifetime, in particular the Platform Management Credentials, Provisioning MSISDN, are stored in the SM-SR database. Without this step, remote access to the eUICC will be impossible
- If MNO A manages their profiles with a different SM-SR than MNO B then the management of the eUICCs will be handed over. In this case SM-SR X will request the necessary data to manage the eUICCs (e.g. the appropriate access credentials, characteristics of the eUICCs, previous SM-SRs) in the M2M devices from SM-SR Y. SM-SR X will not want the SM-SR Y to have knowledge of the eUICC profile management credentials it will have. Therefore SM-SR Y and SM-SR X perform a change of eUICC management responsibilities involving the eUICCs in the process. As a consequence SM-SR X becomes the entity managing the eUICCs on behalf of the MNO A.
