Subscriber identity module activation for NB-IoT devices

A narrow band Internet of Things (NB-IoT) device having a subscriber identity module (SIM) configured to connect to a cellular network, the NB-IoT device comprising:

• a processor;
• a subscriber identity module (SIM);
• and
• a memory storing instructions that, when executed, cause the processor to perform acts comprising:
• determine a SIM status for connecting the NB-IoT device to the cellular network, wherein the SIM status is a locked status or an unlocked status;
• in response to determining that the SIM status is the unlocked status, connect the NB-IoT device to the cellular network, wherein the NB-IoT device connected to the cellular network is not configured to access NB-IoT-specific functions;
• in response to determining the SIM status of the NB-IoT device is the locked status, access, as an accessed NB-IoT SIM value from the SIM of the NB-IoT device;
• compare the accessed NB-IoT SIM value to a reference NB-IoT SIM value;
• and
• in response to comparing the accessed NB-IoT SIM value to the reference NB-IoT SIM value, connect the NB-IoT device to the cellular network, wherein the NB-IoT device connected to the cellular network is configured to access NB-IoT-specific functions, including a radio policy management functionality.

A non-transitory computer readable media for a use with a narrow band Internet of Things (NB-IoT) device including a subscriber identity module (SIM), the non-transitory computer readable media including instructions that when executed by a computer, cause the NB-IoT device to perform acts comprising:

• determine a subscriber identity module (SIM) status for connecting the NB-IoT device to a cellular network, wherein the SIM status is a locked status or an unlocked status;
• in response to determining the SIM status is the unlocked status, connect the NB-IoT device to the cellular network, wherein the NB-IoT device connected to the cellular network is not configured to access NB-IoT-specific functions;
• in response to determining that the SIM status of the NB-IoT device is a locked status, accessing, as an accessed NB-IoT SIM value from the SIM of the NB-IoT device;
• compare the accessed NB-IoT SIM value to a reference NB-IoT SIM value;
• and
• in response to comparing the accessed NB-IoT SIM value to the reference NB-IoT SIM value, connect the NB-IoT device to the cellular network, wherein the NB-IoT device connected to the cellular network is configured to access NB-IoT-specific functions, including a radio policy management function.
