performing a mobile device authentication procedure between the first mobile device and the mobile network; and performing by the mobile network, a location update operation using identifier information including subscriber information. ## Claims ### Claim 1 A mobile device comprising: a first processor and a first- non-transitory machine readable medium having stored thereon a first program having program code for performing the following steps: transmitting an enable request to an integrated circuit card, receiving an enable response from the integrated circuit card, transmitting an attach request to a mobile network, the attach request comprising a subscriber identifier; and the integrated circuit card comprising a second processor, and a second non-transitory machine readable medium having stored thereon a second program having program code for performing the following steps: receiving the enable request from the first processor, and enabling a first profile stored on the integrated circuit card in response to the enable request, and transmitting the enable response to the first processor. ### Claim 2 (depends on 1) The mobile device of claim 1, wherein: the first program further comprises program code for performing the following steps: receiving an attach reject message from the mobile network, and sending a rejection event to the integrated circuit card; and the second program further comprises program code for performing the following steps: receiving the rejection event; and disabling the first profile in response to receiving the rejection event. ### Claim 3 (depends on 2) The mobile device of claim 2, wherein the first processor is configured to maintain a connection with the mobile network from a time of the transmitting the attach request to a time of sending the rejection event to the integrated circuit card. ### Claim 4 (depends on 1) The mobile device of claim 1, wherein the first program comprises baseband firmware. ### Claim 5 (depends on 1) The mobile device of claim 1, further comprising a communication interface coupled to the first processor, wherein the step of transmitting the attach request to the mobile network is performed using the communication interface. ### Claim 6 (depends on 5) The mobile device of claim 5, wherein the communication interface is coupled to the first processor via the integrated circuit card. ### Claim 7 (depends on 1) The mobile device of claim 1, wherein: the mobile network comprises an LTE network; and transmitting the attach request to the mobile network comprises transmitting the attach request to a Mobility Management Entity (MME) via an eNodeB. ### Claim 8 (depends on 1) The mobile device of claim 1, wherein the integrated circuit card comprises an embedded Universal Integrated Circuit Card (eUICC). ### Claim 9 A method of operating a mobile network, the method comprising: receiving an attach request from a first mobile device having a first profile stored thereon, the attach request comprising subscriber information; transmitting an authentication information request to a Home Subscriber Server (HSS) in response to receiving the attach request; receiving an authentication information response from the HSS, the authentication information response comprising authentication vectors relating to the subscriber information; transmitting an update location request to the HSS requesting to update a location associated with the first mobile device and the subscriber information; receiving an update location response from the HSS; and transmitting an attach reject message to a second mobile device having the first profile stored thereon. ### Claim 10 (depends on 9) The method of claim 9, wherein the mobile network comprises an LTE network. ### Claim 11 (depends on 10) The method of claim 10, wherein: receiving the attach request comprises receiving the attach request via a first eNodeB; and transmitting the attach reject message comprises transmitting the attach reject message via a second eNodeB different from the first eNodeB. ### Claim 12 (depends on 9) A non-transitory machine readable medium having stored thereon a program having a program code for performing the method of claim 9, when the program is executed on at least one processor. ### Claim 13 An integrated circuit card comprising: a local processor, and a non-transitory machine readable medium having stored thereon a first program having program code for performing the following steps: receiving a first enable request from a first processor, enabling a first profile stored on the non-transitory machine readable medium in response to the first enable request, transmitting a first enable response to the first processor, receiving a first rejection event from the first processor, and disabling the first profile in response to receiving the first rejection event. ### Claim 14 (depends on 13) The integrated circuit card of claim 13, wherein the integrated circuit card is a Universal Integrated Circuit Card (UICC). ### Claim 15 (depends on 13) The integrated circuit card of claim 13, wherein the integrated circuit card is an embedded Universal Integrated Circuit Card (eUICC). ### Claim 16 (depends on 13) The integrated circuit card of claim 13, wherein the non-transitory machine readable medium further has stored thereon a second program having code for performing the following steps: receiving an authentication request from a host; and sending an authentication response to the host in response to the authentication request. ### Claim 17 (depends on 16) The integrated circuit card of claim 16, wherein: the local processor is configured to be coupled to a communication interface; and the local processor is configured to communication directly with the host via the communication interface. ### Claim 18 (depends on 13) The integrated circuit card of claim 13, wherein the first program further comprises program code for performing the following steps: receiving a second enable request from the first processor, enabling a second profile stored on the non-transitory machine readable medium in response to the second enable request, transmitting a second enable response to the first processor, receiving a second rejection event from the first processor, and disabling the second profile in response to receiving the second rejection event. ### Claim 19 (depends on 13) The integrated circuit card of claim 13, wherein the first profile comprises subscriber information for a mobile network. ### Claim 20 (depends on 19) The integrated circuit card of claim 19, wherein the mobile network is an LTE network.
