Hello,
thank you for your question. In order to find out what is the firmware please insert a SIM card and send an SMS command "getver" to that number. Please see below:
login pass getver
If this is a new device with default configuration, there will not be login or password configured so please just leave two spaces in front of the command. Then you will receive a response with device's IMEI number, firmware version etc. Once you have your firmware version then please contact your sales manager and ask for correct configurator.
Thank you and have a nice day.
