Profiles
In the following section, all the parameters that need to be configured for a
connection (such as APN, user name, password, DNS server addresses etc.) are
referred to as a profile. Every profile is identified by an arbitrary, unique name. The
profile named
Default
is special in that it is always present and can neither be edited
nor deleted. (A sample dialog box is presented in Figure E.4 on page 8.) The
Default
profile uses parameters from a built-in database. The home network (the
network that issued the SIM) is used for the database look-up. While there can be
many configured profiles, only one profile can be active at any time.
If connection profiles are configured manually, the
Enable automatic
configuration
checkbox should normally be unchecked.
In one particular use case, manually configured profiles may be combined with
automatic configuration. If multiple SIM cards are used with the same device, each
SIM card being from a different operator and some or all of them requiring a
manually set up profile, automatic configuration may be used to automatically pick
the correct manually configured profile for each SIM card. For this to work, each
profile must be configured while the corresponding SIM card is inserted in the
device and initialized (i.e. the status is at least
SIM is ready
).
The
Select profile:
drop-down list in the data configuration profile selects to which
profile a subsequent action applies. A profile named
Default
is always present and
contains the current parameters from the database. The following actions are
available:
Show
The parameters for the selected profile are displayed when you tap the stylus on this
button. For the
Default
profile, the publicly known password is shown—otherwise,
the password is hidden.
Edit
The parameters of the selected profile can be edited when you choose the
Edit
button. Keep in mind that you
cannot
edit the
Default
profile.
Delete
The selected profile is deleted. You
cannot
delete the
Default
profile.
