Methods, apparatus and systems are presented that enable a network operator to control the source for network services in open market devices by provisioning the network operator-issued removable modules with network service provisioning information associated with the operator and configuring the open market wireless devices such that the device looks to the removable module first for the network service provisioning information before looking to device storage for any other provisioning information related to the network service. In this regard, the user of the open market wireless device is still provided access to the network service even if the network operator does not provide the service or provide access to the service. Additionally, the described aspects methods, systems and apparatus provide the network operator with an additional level of dynamic control over the source for network services by providing for a network-side proxying feature that allows the network operator to proxy network service requests sent from the open market wireless devices to a designated third party network service provider based on criteria defined by the network operator.
