Settings 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. • 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 - The options are Yes / No. • Login script - Insert the login script. • Modem initialisation (Modem initialisation string)- Controls your phone using modem AT commands. If required, enter characters specified by your GSM network service provider or Internet service provider. 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. 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. Go to Settings→ Connection settings→ GPRS.
