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.
