Will receiving text messages definitely turn you into red team?

As long as there is no close contact, it will not change color, and making a phone call will have no effect.

The health code will change color only if:

1, as well as confirmed cases, asymptomatic infected people. In the same place or nearby area, someone in your community is infected, and the health code will turn yellow and red.

2. When the mobile phone is turned on, it can receive communication roaming information. In high and medium risk areas, after staying at 1 hour, the health code will automatically turn yellow and red.

3. If you take public transportation such as high-speed rail, train and plane, and there are suspected or confirmed cases in the same car, then you are a close contact, and your health code will turn yellow or red.
