The method includes implementing an intelligent Mobile Device Access Network Manager (iMDANM) application on a Universal Integrated Circuit Card (UICC). The iMDANM application being configured to allow a foreign wireless service provider to lease a portion of the UICC from the home wireless service provider to provision service credentials to the leased portion of the UICC, thereby providing the mobile device access to a foreign network operated by the foreign wireless service provider. ## Claims ### Claim 1 A method, comprising: obtaining, by a negotiation server, information indicative of foreign networks available at a location of a mobile device, wherein the foreign networks are not roaming partners of a home wireless service provider that provides cellular access to the mobile device, wherein a home network operated by the home wireless provider is not accessible at the location of the mobile device, and wherein the negotiation server is a third party server that is not affiliated with any of the foreign networks; receiving, by the negotiation server, subscriber credentials from the mobile device to authenticate the mobile device for a lease agreement for providing cellular access to the mobile device; selecting, by the negotiation server, a foreign network among the foreign networks available at the location of the mobile device; and negotiating, by the negotiation server, the lease agreement between the home wireless servicer provider and a foreign wireless service provider of the selected foreign network to lease a portion of a universal integrated circuit card of the mobile device, provided by the home wireless service provider, to the foreign wireless service provider, for provisioning service credentials to provide the mobile device with cellular access to the selected foreign network operated by the foreign wireless service provider, wherein the subscriber credentials include a lease duration and charging policies between the home wireless service provider and the foreign wireless service provider of the selected foreign network. ### Claim 2 (depends on 1) The method of claim 1, further comprising authenticating the subscriber credentials with the home wireless service provider. ### Claim 3 (depends on 1) The method of claim 1, wherein obtaining the information indicative of the foreign networks available at the location of the mobile device comprises detecting the foreign networks available at the location of the mobile device. ### Claim 4 (depends on 1) The method of claim 1, wherein obtaining the information indicative of the foreign networks available at the location of the mobile device comprises receiving the information from the mobile device. ### Claim 5 (depends on 1) The method of claim 1, wherein local applications on the universal integrated circuit card are accessible to the mobile device while the mobile device is provided with cellular access to the selected foreign network operated by the foreign wireless service provider ### Claim 6 (depends on 1) The method of claim 1, wherein upon expiration of the lease agreement prior to the lease duration, fees for a remaining portion of the lease agreement are refunded based upon charging policies. ### Claim 7 (depends on 1) The method of claim 1, wherein the subscriber credentials are received from the mobile device responsive to a user of the mobile device selecting an option to enter the lease agreement. ### Claim 8 A device, comprising: a processor; and a memory having stored thereon instructions which, when executed by the processor, cause the processor to perform operations comprising: receiving information indicative of foreign networks available at a location of a mobile device, wherein the foreign networks are not roaming partners of a home wireless service provider that provides cellular access to the mobile device, wherein a home network operated by the home wireless provider is not accessible at the location of the mobile device, and wherein the negotiation server is a third party server that is not affiliated with any of the foreign networks; receiving subscriber credentials from the mobile device to authenticate the mobile device for a lease agreement for providing cellular access to the mobile device; selecting a foreign network among the foreign networks available at the location of the mobile device; and negotiating the lease agreement between the home wireless service provider and a foreign wireless service provider of the selected foreign network to lease a portion of a universal integrated circuit card of the mobile device, provided by the home wireless service provider, to the foreign wireless service provider, for provisioning service credentials to provide the mobile device with cellular access to the selected foreign network operated by the foreign wireless service provider, wherein the subscriber credentials include a lease duration and charging policies between the home wireless service provider and the foreign wireless service provider of the selected foreign network. ### Claim 9 (depends on 8) The device of claim 8, wherein obtaining the information indicative of the foreign networks available at the location of the mobile device comprises detecting foreign networks available at the location of the mobile device. ### Claim 10 (depends on 8) The device of claim 8, wherein obtaining the information indicative of the foreign networks available at the location of the mobile device comprises receiving the information from the mobile device. ### Claim 11 (depends on 8) The device of claim 8, wherein local applications on the universal integrated circuit card are accessible to the mobile device while the mobile device is provided with cellular access to the selected foreign network operated by the foreign wireless service provider. ### Claim 12 (depends on 8) The device of claim 8, wherein upon expiration of the lease agreement prior to the lease duration, fees for a remaining portion of the lease agreement are refunded based upon charging policies. ### Claim 13 (depends on 8) The device of claim 8, wherein the subscriber credentials are received from the mobile device responsive to a user of the mobile device selecting an option to enter the lease agreement. ### Claim 14 A computer-readable storage device having stored thereon instructions which, when executed by a processor, cause the processor to perform operations comprising: receiving information indicative of foreign networks available at a location of a mobile device, wherein the foreign networks are not roaming partners of a home wireless service provider that provides cellular access to the mobile device, wherein a home network operated by the home wireless provider is not accessible at the location of the mobile device, and wherein the negotiation server is a third party server that is not affiliated with any of the foreign networks;
