Packet data
The packet data settings affect all access points using a packet data connection.
Packet data connection—If you select When available and you are in a network
that supports packet data, the phone registers to the packet data network and
short messages are sent using a packet data connection. If you select When
needed, the phone uses a packet data connection only if you start an application
or function that needs it. The packet data connection can be closed when it is not
needed by any application.
If there are no packet data services available and you have chosen When available,
the phone periodically tries to establish a packet data connection.
Access point—The access point name is needed when you want to use your phone
as a modem with your computer.
High speed packet access — Enable or disable the use of HSDPA (network service)
in UMTS networks.
