[74xx] How to read SIM Linear Fixed Struct from ADF

Hi All
I want to read SIM Linear Fixed from ADF (such as : ISIM) with QMI or AT-Command.
We have try the issue 1 month, but still can not found solution.

  1. For AT command, we can read Linear fixed struct data, but we can’t select to ADF.
  2. For QMI qa sample code

    doSLQSUIMGetFileAttributes => it can’t read any sim card information.
    doSLQSUIMReadTransparent => it only can read Transparent struct and can’t switch to ISIM(ADF).

Does anybody can provide some information on the issue?
I want switch to ISIM and read linear fixed data by QMI or AT-command.

Many thanks
