Hello Bruno,

If you could give me more details on this. Do you have any txt/ini file on the device which stores this custom attribute?

Hi

Actually we just put it manually from the webconsole on each device, is there a better way ?

Custom attributes are primarily meant for administrator to set parameters from MobiControl server side to be downloaded to the device side.

In your case requiring data input by device end-users uploaded from device to MobiControl server, you should use custom data instead.   If your SIM cards can be read out by the firmware of your device ,  the ICCID and phone number associated with such SIM cards should normally be reported back automatically to the server by default, without the need for you to add any custom data.

Unfortunately the SIM cars Number into the device is different to the number of the SIM card (check digit) so we can't use custom data.

Actually Im' not sure that my solution is the best and the easiest, do you think we can do that differently ?

Thanks

 To use custom data mechanism to report back phone number to your server, you need an app that can correctly read the phone number and then put the data into an xml/ini file of the right format for custom data collection.
