using a packet data connection.
Select from the following:
●
Packet data connection
— If you select
When
available
and you are in a network that supports
packet data, the device registers to the packet
data network. Starting an active packet data
connection (for example, to send and receive e-
mail) is quicker than if the device establishes a
packet data connection when needed. If there is
no packet data coverage, the device periodically
tries to establish a packet data connection. If you
select
When needed
, the device uses a packet
data connection only if you start an application
or action that needs it.
●
Access point
— The access point name is needed
to use your device as a packet data modem to a
compatible computer.
●
High speed packet access
— Enable or disable
the use of HSDPA (network service) in UMTS
networks.
