A method and apparatus for accessing wireless carrier networks by mobile computing devices. An access client hosted by a mobile computing device accesses carrier networks using wireless access points. The access client uses an access point database to identify access points and carrier networks. The access client uses a methods database and a tokens database to access the carrier networks. The access client updates the access point database, the methods database, and the token database using an access server when the access client is operably coupled to a carrier network. The access client transmits user information to the carrier network. The carrier network uses the user information to authenticate the user and to generate session data while the user is accessing the carrier network. The carrier network transmits the session data to the access server. The access server uses the session data to generate billing information for the user. The access client also collects network performance data for individual access points and carrier networks. The access client transmits the network performance data to the access server. The access server aggregates network performance data from a plurality of access clients to generate quality of server reports for both individual access points and carrier networks. The access client further includes access point detection and evaluation features for use by a user in selecting access points available at a single location.
