This project allows you to use our, more recent, Java modules to read SIM card 4G Elementary Files - with just AT Commands - no Java programming needed.

The SIM card's 4G readiness heutistic is made possible via the Gemalto Java AT Command Extensions (JAT).

You can add new AT Commands to the ELS61 rel 1 "MR" / ELS61 rel 2 / PLS62-W rel 2 and EHSx rel 4 modules.

No Java programming needed - drive everything just using AT Commands!

How to use:

The following example shows an example of a known bad USIM, does not allow 4G registration.

Part 1 shows starting the Java application to enable an extended AT Command
Part 2 shows the reading of the SIM card EF files
Part 3 shows the reporting of the recommended RaT for the current 4G module
Part 4 shows stopping the Java application to end use of the extended AT Command

Part 1 - starting the Java application to enable an extended AT Command
