I have designed the LTE modem with sim card by using sim7600E module.for testing this device i am using QUECTEL Qnavigator software tool. the functioning of this device is good, responding for all necessary AT commands Except one command that is AT+QCCID.this command is related to the sim card information. while testing this command the sim card information shows empty and the AT+QCCID ERROR after that it shows a pop up message like "fail to query ICCID number of sim card"
for better understanding please take a look into the below attached files.
