Methods and apparatus in a wireless device for use in maintaining appropriate authentication credentials for receiving a message service provided by a service network which is external to a wireless network are described. The wireless device receives, via the wireless network, a data session configuration file which includes a list of a plurality of wireless networks mapped against authentication credentials associated with each said wireless network. The list includes authentication credentials associated with the wireless network. The wireless device submits, via the wireless network, the authentication credentials for establishing a data session via the wireless network. Then, the wireless device receives, in the data session via the wireless network, the message service provided by the service network. Prior to receiving the file, the wireless device may maintain default authentication credentials associated with a default wireless network, submit via the default wireless network the default authentication credentials for establishing a data session via the default wireless network, and receive in the data session via the default wireless network the message service provided by the service network. |
