Mno-specific functionality information delivery

A computer-implemented method, comprising:

• receiving a request from a mobile network operator (MNO) to provide MNO-specific 5G functionality information of the MNO to a user device;
• storing the MNO-specific 5G functionality information in an Embedded Subscriber Identity Module (eSIM) profile that is associated with the MNO;
• and
• directing a file transfer service of the MNO to send the eSIM profile to the eSIM of the user device,
• wherein the MNO-specific 5G functionality information instructs the user device to use an encryption key stored in a user device or the eSIM of the user device to encrypt or decrypt subscriber identifier information of the user device for 5G communications exchanged between the user device and a core network of a wireless carrier network operated by the MNO.

A user device, comprising:

• one or more processors;
• and
• memory including a plurality of computer-executable components that are executable by the one or more processors to perform a plurality of acts, the plurality of acts comprising:
• in response to receiving mobile network operator (MNO)-specific 5G functionality information of an MNO via an Embedded Subscriber Identity Module (eSIM) profile, storing the eSIM profile in an eSIM of the user device;
• and
• in response to receiving the MNO-specific 5G functionality information of the MNO via an update package, storing the update package in a trusted environment of the user device,
• wherein the MNO-specific 5G functionality information configures the user device to or instructs the user device to perform one or more operations related to using 5G telecommunication services provided by the MNO.
