The traffic is about to run out, and 10086 sent a short message saying that 2 yuan 10M packet traffic is superimposed. What does this mean?

This is a data traffic 2 yuan overlay package launched by Mobile, which will take effect immediately after opening and will be cancelled automatically at the end of the month. There may be some subtle differences in each region! Please consult local 10086 for details.

Take Sichuan Mobile as an example: 2 yuan contains 15m traffic, which will take effect immediately after opening and will be cancelled automatically at the end of the month, and can be purchased for 4 times.
