Systems, methods, computer software for providing access to wireless communication services are provided. The invention, in one embodiment, can involve storing a network address on a mobile device and sending a request for network operator data from the mobile device to a mobile virtual network operator server associated with the network address. In response, network operator data is received, and, based on the received network operator data, a network operator is selected. Communications are thereafter conducted using the selected network operator. In some situations, bids are received from multiple network operators for rates at which communication services using each network operator can be obtained. Preferences among the network operators are identified using the received bids, and the preferences are used to select the network operator for the mobile device to use in conducting communications.
