Hello .
I’m using EC200U for dual sim function.
When i use “AT+QDSIMI?” command for get usim imei it got “+CME ERROR: 58”.
Also i can use “AT+QDSIM=0 or 1” and it works fine.
I already updated the firmware and the current firmware is “EC200UEUAAR02A06M08”
is it need to upgrade the firmware to another version??
Hello,
If you know python you can use the firmware from the link below, then you do all through the python “main.py” script
