Here are some tips if you have problems with Ulefone brand validation devices

First of all, make sure the device is fully charged and you have access to a stable Wi-Fi network.

  • Note that a municipal internet network (ile sans fil or Zap) is not considered reliable.

  • Moreover, even if the device is connected to a Wi-Fi network, it doesn't mean the internet connection is strong enough. Make sure to test before your event to avoid unpleasant surprises.
