A method and system to allow wireless devices, such as wirelessly-equipped digital cameras, to gain wireless packet-data connectivity and to interact with a media management server, such as a photo server. A wireless carrier distributes multiple devices all having the same set of radio access data (e.g., mobile identification number and electronic serial number), and all having shared or unique pre-registration data. Any such device can then readily use the shared radio access data to acquire radio connectivity and can then use the pre-registration data to gain access to the media management server. The first time such a device connects with the media management server using the pre-registration data, the server will engage in a online account registration session with the device and provision the device with post-registration data that the device can thereafter use to access the online account.
