China Mobile SMS said that the traffic is not used up. How to calculate the charge in proportion?

I only heard that the package application is not at the beginning of the month, so the fee is calculated by the day. I have never heard of the saying that the traffic is not used up. If the traffic is used for a whole month, it will be charged according to the package fee/month. If you really need to calculate according to what proportion, it may be the total monthly flow * 12/365= actual daily flow and then calculate according to the day you use it.
