    Hi, I am working with Raspberry Pi 3G/4G&LTE Base HAT and quectel EC25-E

    Bus 001 Device 008: ID 2c7c:0125 Quectel Wireless Solutions Co., Ltd. EC25 LTE modem

    The module is responding successfully to AT commands, however, it does not detect the Sim Card. I just tried 2 different Sim cards, but same behaviour. Any ideas?

    Commands:

    OK
    at+cpin?
