The new model of UCM/GSM4 module which works on the 3G network is now available, model number UCM/GSM4(3G).
 
This is necessary in countries where the 2G network has been shut down, like Singapore and Australia, with other countries perhaps following suit in a few years
Even where the 2G network is available, there are several advantages to UCM/GSM4(3G). - Some 3G Sim card plans may actually be cheaper for network providers which do not support 2G
- Dialing to Central Monitoring Stations via 3G GSM is reliable compared to 2G. 2G dial out to Central Monitoring stations does not work reliably over 2G GSM because of speed and delays over the network, but this is not a problem for 3G
- Higher security for 3G over 2G because of encryption, reduced chances of impersonation.
The 2G UCM/GSM4 with 2G is renamed UCM/GSM4(2G)
The UCM/GSM4 Manual has been revised to include 2G and 3G models and can be downloaded from https://www.cytech.biz/ucmgsm_manual.html
UCM/GSM4 firmware 7.097 supports both UCM/GSM4(2G) and UCM/GSM4 (3G)
Comfigurator should be updated to Comfigurator 3.11.10
UCM/GSM4 Firmware must be updated to the min 7.047 and above
UCM/GSM4(3G) costs more than the UCM/GSM4(2) because of the 3G module
NOTE:
If the GSM4 submodule is replacing an older GSM module , make sure that the Base UCM has a U2 EEPROM (24LC256)
