Abstract
There is described a method, at a server system, of providing a mobile network operator (MNO) profile to a client device. The client device has a SIM software application stored thereon so as to provide the client device with a secured software implementation of SIM card functionality. The method comprises: (a) based on a unique identifier of the client device, identifying a unique key, K, of the SIM software application stored on the client device; (b) based on an MNO associated with the client device, identifying an unused MNO profile associated with the MNO; (c) encrypting the identified MNO profile so as to provide an encrypted MNO profile, wherein the encrypting comprises encrypting at least part of the identified MNO profile using K; (d) generating an MNO profile download message comprising the encrypted MNO profile and the unique identifier of the client device; and (e) broadcasting the MNO profile download message over a broadcast network so as to enable the client device to access the MNO profile download message. There is also described a related method at a client device, as well as related computer programs and computer-readable media.
