Data Transfer Comparison of GSM with GPRS
GPRS handset
Classes:
- Class A mobile phones can be connected
to both GPRS and GSM services simultaneously.
- Class B mobile phones can be attached
to both GPRS and GSM services, using
one service at a time. Class B enables
making or receiving a voice call, or
sending/receiving an SMS during a GPRS
connection. During voice calls or SMS,
GPRS services are suspended and then
resumed automatically after the call
or SMS session has ended.
- Class C mobile phones are attached
to either GPRS or GSM voice service.
You need to switch manually between
services.
