Note: The phone expects the callback call to use the same data call settings 
that were used in the callback-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.
 / 
Use other no.
 Ask your service provider for 
the correct setting to use; it will depend on the service provider’s configuration.
 Glossary: PPP 
(Point-to-Point Protocol) - 
a common networking 
software protocol that 
enables any computer 
with a modem and a 
phone line to connect 
directly to the Internet.
Callback number
 - Key in your phone’s data phone number which the dial back server 
uses. Usually, this number is the data call phone number of your phone.
Use PPP compression
 - When set to 
Yes
, this option speeds up the data transfer, if 
supported by the remote PPP server. If you have problems with establishing a 
connection, try setting this to 
No
. Contact your service provider for guidance.
Use login script

 /

Modem initialisation

AT commands. If required, enter characters specified by your GSM network service

GPRS
 Go to 
Settings
→ 
Connection
→ 
GPRS
.
The GPRS settings affect all access points using a packet data connection.
GPRS connection
 - If you select 
When available
 and you are in a network that supports 
packet data, the phone registers to the GPRS network and sending text messages will be 
done via 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 will use a packet data 
connection only if you start an application or action that needs it. The GPRS connection 
is closed after it is not used by any application. 
Note: If there is no GPRS coverage and you have chosen 
When available
, the phone 
will periodically try to establish a packet data connection.
