This option allows the user to specify the APN that will be used for the connection.

There are 3 separate cases as detailed below.


1. In the first case, the application will attempt to make an automatic connection using the default APN for the specific home network; this assumes that the device correctly presents its home network.


2. In the second case, the user is presented with a list of operators from which they can select when they initiate or connection is initiated automatically.


3. In the third case, the user can manually set the APN settings they require.  No checks are made on the validity of this information.


The user selects the appropriate choice and as necessary provides information.
