NASCONFIG file missing or file configuration help
Background: Some of our UICC (SIM) cards don't have this file or it's too small. Please contact our support to get help and a script to create the file on the card (if you purchased the SIM card from us obviously). Furthermore Card Admin doesn't “interpret” the content of the file, so you have to learn how to configure it in binary mode with the help of the ETSI specifications.
Once you get the script from us, run it and the file will be created.
If you use Card Admin you will get a ATF script and a description on how to run it is described here:
We'll just point out the basics here, and you'll have to do the rest (like looking into TS 24.368, http://www.arib.or.jp/IMT-2000/V900Jul11/5_Appendix/Rel10/24/24368-a00.pdf that describes the coding for the content)
So the 6FE8 file is empty or contains Tags. The tags are currently: 80,81,82,83,84 and 85. It can contain 1 tag or all 5.
80 NAS signalling priority
81 NMO I Behaviour Content
82 Attach with IMSI Content
83 Minimum Periodic Search Timer
84 Extended access barring
85 Timer T3245
The file is filled with TAG – LENGTH of content – CONTENT
For example, if you have NAS signalling priority with content 01 (NAS signalling low priority) and Timer T3245 with content 01 (Timer used) and length 1 byte = 01, the value in the file is:
80 01 01 85 01 01 FF FF FF FF….
Contents are described in TS 24.368 . (see link above)
Unused bytes shall be set to 'FF'
Lookup section 4.2.94 EFNASCONFIG (Non Access Stratum Configuration)
UST Services in byte 12
