      I successfully read SD card on my sim7600g, I mean I have "SDCard Size: 3789MB" when I run examples/Arduino_TinyGSM/AllFunctions/AllFunctions.ino. The SD card is formatted as FAT32 on Windows 10, no partition. I suggest to run one of examples such as AllFunctions.ino first.

        @caz Hello,
        Thanks for your reply.
        Unfortunately I have tested my board with all the different exemples from the Arduino library and the result are always the same "SD card mount fail".
        I have formated the various SD card on Windows 10 and MAC OS as FAt32 with the same result.
        Regards

          @papbo How do you attache the SD? Does its contact side face to the board? Its connector is not fail safe.

              @caz hello, do you have a sketch to test the SD card on the SIM7600...other than the examples (they are not working here)

                @papbo AllFunctions.ino has following code.

                //Initialize SDCard
                SPI.begin(SD_SCLK, SD_MISO, SD_MOSI, SD_CS);
                if (!SD.begin(SD_CS)) {
                Serial.println("SDCard MOUNT FAIL");
                } else {
                uint32_t cardSize = SD.cardSize() / (1024 * 1024);
                String str = "SDCard Size: " + String(cardSize) + "MB";
                Serial.println(str);
                }

                    @papbo Does you code have serial port initilization code?

                    // Set console baud rate
                    SerialMon.begin(115200);
                    delay(10);

                    // Set GSM module baud rate
                    SerialAT.begin(UART_BAUD, SERIAL_8N1, MODEM_RX, MODEM_TX);
