By default, the Wi-Fi SD card will automatically broadcast wireless network signal when the camera is powered on. You should see the SSID (WIFISD) in the Wi-Fi setting of your mobile deivce.
To avoid Wi-Fi disconnection when camera goes into power saving mode, we suggest you turn on "Live View" or adjust (turn off) the timer of "power saving mode".
If you do not have “Live View” function, please adjust the time of Auto meter-off delay or Standby Timer in the settings (C2, suggested to adjust to 5 mins or more).
