What does the supplementary charge in Unicom's phone bill mean?

Supplementary charge is a kind of charge. In layman's terms, it is the fee charged for making up the short board. For example, there is a minimum monthly consumption in the business handled, and the monthly consumption does not reach the minimum consumption, and a "supplementary fee" is required. For example, if the monthly minimum consumption of 60 yuan is only used in 40 yuan, there will be a supplementary fee of 65,438+00 yuan. You can log in to the mobile phone business hall to inquire about the specific consumption situation according to the following steps.
