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 pre-
sented on the page following.) 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 then 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, auto-
matic configuration may be used to automatically pick the correct manually configured 
profile for each SIM card. For this to work each profile has to be configured while the corre-
sponding 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 which profile a 
subsequent action applies to. 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 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.

•

Activate – When this button is chosen, the selected profile is made the active profile. 

Activation is possible only if the Enable automatic configuration: checkbox is 

unchecked.
