Testing

• Insert the SIM card and earphone to the SIM7600X board, if you want to test the TF card slot, you can also insert a TF card to the card slot.
• Connect the USB interface of SIM7600X board to PC.

• The PWR indicator turns on after connecting
• Long-press the PWR button for 1, the NET LED turns on and became flashing after 10s. (If the NET indicator keeps solid, please check if the SIM card is workable)
• Check the Device Manager of PC, the several COM ports will be recognized:

• If the COM ports are recognized with an exclamation symbol, you should install the driver manually.
• Connect the DONGLE to Windows PC (Hereafter we use Windows 10 PC as example)）
• Open Device Manager—>Other Devices—>“SimTech, Incorporated”—>Update driver—>Browse my compute for driver software—>Choose the driver according to your OS—>Install it
