Isn't there a SMS fee in my package? What's the point? How can I query when the number of articles is used up?

At present, most packages don't include free SMS (that is, you have to pay extra for sending messages), but some numbers of Shenzhouxing and M-Zone are added separately in the old package, which is separate from the main package. In this case, the SMS package still exists after upgrading the main package, and in this case, sending messages is free (within the number of free SMS, beyond the extra charge). . . You can log in to the mobile phone business hall, or go to the physical business hall to inquire about the detailed list of your mobile phone package, or call customer service, so that you can know whether you have a short message package, and if so, how many short messages are free.
