If you are using a standard FM1100 it will accept GPRS based commands, you do not need any special changes. In Wialon you just need to mak sure that you set up commands for the units.
The command can only be sent if the unit has an active GPRS session.
I am having a firmware modification done to have 150 geozones stored on the device so we can set up a route and route management using only sms and to both the monitoring application and a mobile phone.
The current firmware version is FM11010720.e and the configurator is 220.127.116.11. This also has a fix for a GPS bug.
