When you have selected 
GPRS
 as a data bearer, the device uses EGPRS instead of 
GPRS if it is available in the network. You cannot select between EGPRS and GPRS 
in your device, but for some applications, you may be able to select either 
GPRS
 or 
GSM data
 [CSD—circuit switched data] as the data bearer. The data bearer is part 
of the preferred access point and can be changed in 
Configuration settings
 [see  
The applications that may use GPRS are MMS, instant messaging, browsing 
sessions, e-mail, remote SyncML, Java application downloading, and the PC 
dial-up [for example, Internet and e-mail].
Before you can use GPRS technology, contact your service provider for availability 
of and subscription to the GPRS service and save the GPRS settings for each of the 
applications used over GPRS.
