Failed to detect SIM card with WS1 Pro device (WiFi and SIM version)

When the voice guide says” No SIM card was found, sync failed” , you can check the problems from the aspects as listed below.

  1. Check if the SIM card was installed correctly. The notch should face the down right corner.
  2. SIM card consumes much more power to sync the data than the WiFi modes. Please try again with USB power supply (5V/2A).
  3. Please make sure that the SIM card clicked into the slot.
