1. A method for remote provisioning of a subscriber identity module (SIM) profile to a subscriber entity, the method being performed by a remote SIM provisioning server, the method comprising:
obtaining a request from a mobile network operator (MNO) entity for generation of the SIM profile;
generating the SIM profile;
providing, to a storage entity in a first message, a key-value pair of the SIM profile, the key-value pair comprising a unique identifier comprising at least one profile specific element of the SIM profile as key and hashed binding information of the at least one profile specific element as value, wherein the unique identifier comprising at least one profile specific element of the SIM profile is represented by an integrated circuit card identifier (ICCID) of the SIM profile, and wherein the hashed binding information of the at least one profile specific element is represented by an embedded universal integrated circuit card (eUICC) identity (EID) and profile/subscription unique data elements for the SIM profile comprising a subscriber identifier, a subscriber key, and an operator key, wherein the storage entity is a server, wherein the storage entity, the subscriber entity, the MNO entity, and the remote SIM provisioning server are each separate entities from one another, and wherein the storage entity, the MNO entity, and the SIM provisioning server are each entities of a combined core network and service network; and
providing, to the subscriber entity requesting download of the SIM profile in a second message, the SIM profile, wherein binding information that is not hashed included in the SIM profile received by the subscriber entity from the remote SIM provisioning server is used to verify the hashed binding information provided to the storage entity,
wherein the first message does not comprise the binding information that is not hashed and the second message does not comprise the hashed binding information.
