Do you need data to make a phone call with the itinerary code?

The travel code is not necessarily the telephone data.

There are two ways to query run-length encoding, one is through provincial epidemic prevention APP or the State Council client and various related small programs, which need data function to query. The other way is to send relevant short messages to the operator corresponding to the mobile phone, and the operator will return the list of cities visited by the user within 14 days in the form of short messages. So you don't need to call the data in travel itinerary code, you can also use SMS.

Travel code is the abbreviation of communication big data travel card, and mobile phone network operators monitor the location of mobile phones through signal base stations.

Brief introduction of travel rules

When the user stays in a place for more than 4 hours, the trip code is automatically recorded as the user's passing or visiting. When the administrative area of a city contains medium and high risk areas, the city name of the travel code will be marked with an asterisk.

Although the green travel code with an asterisk will basically not affect travel, it is still necessary to minimize unnecessary travel. If the travel card is marked with an asterisk, it is necessary to confirm whether it has passed through the middle and high risk area and report it to the community unit in time. At present, in most areas, 14 days of concentrated observation and 7 days of health monitoring are carried out for people in middle and high risk areas.

Community units that require centralized and isolated observation should strictly abide by the management regulations of centralized observation points, cooperate with nucleic acid detection and health monitoring, and avoid cross-infection. According to the regulations, home observers should strictly abide by the relevant requirements of home observation during home observation, do a good job in family protection, and report any physical abnormalities in time.
