GPRS
With GPRS (General Packet Radio Service) data is transferred over the network in small, standardized
packets. Transferring data as packets makes the transfer more efficient. Given that the Nokia 30
supports GPRS multi-slot class 6, multiple timeslots can be used for data transfer at the same time.
