Can I send short messages in the month when I open the online messenger service?

If the online messenger service is launched before 15th of each month, it will take effect in that month, and half of the subscription fee will be charged in the first month, including half of the short message volume of the selected package, and short messages can be sent in that month; It will be opened after 15th and will take effect next month. You can't send short messages in that month. (The above content is only applicable to Guangdong Unicom users)
