10 RMB SMS monthly, is there a refund within 24 hours?

After opening, it will be deducted. If it is not issued all the time, it will be deducted at the end of the month. Send one and deduct one. If you know the deduction 10, it will be free.

Whether it is 24 hours or one second after opening (if it is opened immediately), the money will be deducted. If it takes effect next month, it will not be deducted.
