Packet data
The packet data settings affect all access points using a

Select Menu > Tools > Settings > Connection > Packet

Packet data conn. — If you select When available and you

registers to the GPRS network and short messages are sent
using GPRS. Also, starting an active packet data
connection, for example, to send and receive e-mail, is
quicker. If you select When needed, the phone uses a
packet data connection only if you start an application or
function that needs it. The GPRS connection can be closed
when it is not needed by any application.
If there is no GPRS coverage and you have chosen When

data connection.

want to use your phone as a packet data modem to your
computer.
