Why can't Unicom find the itinerary?

It is possible that you can't find the itinerary: if you don't turn on your mobile phone during your stay, you won't generate signaling data, you can't determine your itinerary, and you won't display it. At present, there are too many requests from users all over the country in a short period of time, so it is recommended to wait for a while before trying to obtain them. At present, you need to stay in XX for more than 4 hours before you can find the tourist information. Please try again in a few hours. As one of the important tools for epidemic prevention and control and floating population control in COVID-19, the travel inquiry service is based on COVID-19 14 day risk communication cycle, so it does not provide travel inquiry service for users whose mobile phone access date is within 14 days.
