A user-defined APN can be set via SMS when the required information is not yet in the APN table of the iMetos. Also a station reset via SMS is possible.

Notes:

  • You need the phone number associated to the SIM card in the iMetos 3.3
  • Alternatively, to send the SMS to the SIM card at the iMetos 3.3 you can use a SIM card which already has the configuration SMS locally stored.
  • After sending the SMS described below in this section press the connect button in the iMetos so it checks for received SMS!

 

The following commands can be send via SMS to the iMetos 3.3:

1.      Set user-defined APN:
Code: ! serial_number 0 apn,user_name,password !


serial_number            is the serial number of the station,
apn                            is the APN server address,
user_name                 is the user name of APN server,
password                   is the password of APN server.

 

Example: ! 00200003 0 a1.net,gprs,a1 !

Note: there is no space between the APN parameters but there is one space between exclamation mark, serial number, SMS parameter, APN string and exclamation mark.

When sending this command, the MCC and MNC numbers are taken from the SIM card. Therefore an APN set this way only works for SIM cards with the same MCC and MNC as the in SIM receiving this command (usually this is true for SIM cards of the same provider).
An APN send via SMS is stored in the internal APN XML file, and if correct, is set as default.
If the APN does not work, the system will try to find another APN access from the APN table and the user-defined APN will not be used anymore with the SIM. In order to force the system to retry using a user-defined APN, change the SIM card (as this forces the system to again find a correct APN in the whole APN XML file) or send a new SMS.

To reset the user-defined APN send an SMS without parameters: ! serial_number 0 ,, !

2.      Set user-defined APN full definition:
Code: ! serial_number 3 country_name,MCC,MNC,apn,user_name,password !


serial_number            is the serial number of the station
country_name            is the country of the provider
MCC                           is the MCC of the provider
MNC                           is the MNC of the provider
apn                            is the APN server
user_name                  is the user name of APN server
password                    is the password of APN server

 

Examples: ! 00202233 3 austria,232,1,a1.net,gprs,a1 !

                ! argonaut 3 spain,214,07,movistar.es,movistar,movistar !

Note: there is no space between the APN parameters but that there is one space between exclamation mark, serial number, SMS parameter, APN string and exclamation mark.

This command is equivalent to the command Set user-defined APN, except that the MCC and MNC are set manually.

3.      Reset station:
Code:  ! serial_number 2 UID_station !


serial_number            is the serial number of the station
UID_station                 is the Unique identification number of the station

You can get the UID_number by connecting the iMetos to the PC via USB cable and asking for a quick report (see pages abour USB communication).

This command does a factory reset (exception: the APN table is kept).
