Digital production of subscriber identity modules

A network device, comprising:

• a network interface, for communicating with a network;
• and
• one or more processors, configured to:
• receive over the network a message from an edge device, the message requesting provisioning of a Subscriber Identity Module (SIM) implemented in circuitry of the edge device;
• identify, based on the request, a server assigned to provision the SIM;
• and
• establish a communication connection between the edge device and the identified server, for provisioning the SIM using security credentials that are pre-installed in the circuitry during manufacturing.

A server, comprising:

• a network interface to communicate with a network;
• and
• one or more processors, configured to:
• receive over the network a message from an edge device, the message requesting provisioning of a Subscriber Identity Module (SIM) implemented in circuitry of the edge device;
• and
• in response to the request, send to the edge device at least a portion of a SIM-blob for further provisioning using security credentials that are pre-installed in the circuitry during manufacturing, the portion comprising at least part of a SIM Operating System (SIM-OS) for operating the SIM.

A method in an edge device, the method comprising:

• in an edge communicates over a device that communication network and comprises circuitry that serves as a Subscriber Identity Module (SIM) of the edge device, receiving, over the communication network or over an alternative communication channel, at least a portion of a SIM-blob, the portion comprising at least part of a SIM Operating System (SIM-OS) for operating the SIM;
• storing the SIM-blob in a memory;
• provisioning the SIM-OS using security credentials that are pre-installed in the circuitry during manufacturing and assigned to the SIM;
• and
• carrying out SIM tasks for the edge device using the SIM-OS.
