General Packet Switched Service (GPRS) utilizes packet switched technology where
information is transmitted in small bursts of data. The GPRS mobile station class of the
Nokia 30 is class B. This means that both GPRS connections and circuit switched connec-
tions are possible, although it has to be defined which one is used each time. The Nokia
30 supports GPRS multi-slot class 6, thus multiple timeslots can be used for data trans-
fer at the same time: 3 + 1, 2 + 2 or 2 + 1 slots.
RS-232 connection: All wireless bearers can be controlled either with AT in the AT Com-
mand mode or with CORBA method calls when the terminal is working in the M2M Sys-
tem mode.
