Service Models for Roaming Mobile Device

A method for providing cellular access to a mobile device when the mobile device is out of a home network operated by a home wireless service provider that has no pre-arranged roaming agreements with any foreign wireless service provider in a location of the mobile device. 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.
