Mandatory file apdu error: 6283 upon read. File invalidated

I'm attempting to read EF_LOCI(Location Information) file from a USIM.

1.I'm selecting the MF

->00A40004023F00      
<-622C8202782183023F00A50980017183040001575B8A01058B032F0602C6099001408301018301818104000201069000

2.Now selecting DF TELECOM 

->00A40004027F20
<-622C8202782183027F20A50980017183040001575B8A01058B032F0602C6099001408301018301818104000006DF9000

3.Finally select the EF_LOCI file:

->00A40004026F7E   
<-6283

The result is 6283 for some sims. According to the documentation it means the file is 'invalidated'. Which means what exactly?

If the SIM supports the FDN feature (FDN allocated and activated) a special mechanism shall exist in the SIM which invalidates both EF_IMSI and EF_LOCI once during each GSM session.This mechanism shall be invoked by the SIM automatically if FDN is enabled.

I think this is the reason why, when you try to select EF_LOCI, then the result is SW 0x6283 (File_Invalidated).

Hope this will help you.

This Means, A file will not be longer available for any function except for the SELECT and the REHABILITATE functions unless the file status of the EF indicates that READ and UPDATE may also be performed (that will be set during the EF Creation). File could be Invalidate because of Many reason. For Detail Please refer http://www.3gpp.org/ftp/Specs/archive/11_series/11.11/1111-8e0.zip (annex C).
