3
Device can be attached to both GPRS and GSM services (i.e. Packet Switch and Circuit Switch mode) using one service at a time.
4
The 2G 850 / 1900 MHz and 3G 850 / 1900 MHz bands are mainly operative in America. The 2G 900 / 1800 MHz and 3G 900 / 2100 MHz
bands are mainly operative in Europe, Asia and other countries.
5
The maximum bit rate of the module depends on the actual network environmental conditions and settings.
6
GPRS/EDGE multi-slot class 12 implies a maximum of 4 slots in DL (reception) and 4 slots in UL (transmission) with 5 slots in total.
7
GPRS multi-slot class 10 implies a maximum of 4 slots in DL (reception) and 2 slots in UL (transmission) with 5 slots in total.
8
Device can work simultaneously in Packet Switch and Circuit Switch mode: voice calls are possible while the data connection is active
without any interruption in service.
