Integrated Circuit Card Identifier information
What are the version and build numbers of your MobiControl server?
Are the values in the ICCID column different for each row? Approximately how many rows are there altogether?
Does the ICCID value in the CSV file corresponds to any value (say the first device) in the ICCID column in the device view? If you change the search filter such that the device(s) view get changed (say with the different first device), does the ICCID column in the the CSV file also change accordingly?
