The command needs the SIM module to work correctly.
It is recommended to wait some seconds after boot (or reset) before using the command.

11.2.1î™–î™–î™–î™–Description
Reads the language from the SIM.
The read syntax will display the most preferred language from the preferred language list in EF
ELP
(2F05)
file. If the EF
ELP
file does not exist, the preferred language is read from EF
LP
(6F05) file. This file content
is decoded according to the CB (cell broadcast) data coding scheme (dcs), and the according language is
displayed in the response string. If this byte does not result in a valid language according to the CB dcs,
then it is printed in the response string in hexadecimal representation.
