China Mobile Zhejiang's 2-megabyte mobile phone package sends something to 186. Does this package directly open in the middle of the month and deduct the fee to the traffic in proportion to time?

You can send short messages directly from 3131 to 186 by opening the 2 yuan packet of mobile data traffic.

Zhejiang Mobile adopts the principle that it takes effect on the opening day, and the traffic is charged by the day, that is, you only charge half a month when you open in the middle of the month, and the traffic is counted from the opening day to the end of the month, not by the whole month. Please refer to it.
