The following settings are shown if you have selected data call as the connection type:
Use callback — to allow a server to call you back once you have made the initial call. Contact your service

requesting call. The network must support that type of call in both directions, to and from the phone.
Callback type — The options are Use server no. and Use other no. . Ask your service provider for the correct
setting to use.

problems with establishing a connection, select No . Contact your service provider for guidance.

The packet data settings affect all access points using a packet data connection.
Select Menu > Tools > Settings > Connection > Packet data and from the following options:
Packet data conn. — If you select When available and you are in a network that supports packet data, the phone
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 available , the phone periodically tries to establish a
packet data connection.
