What does the 16 yuan package of Wuhan M-Zone include?

{Wuhan M-Zone SMS Package (New), Wuhan M-Zone SMS Package (New Must-Select Package), Wuhan M-Zone 16 Yuan SMS Package Discount Package (New)} These three basically mean the same thing: 10 Yuan includes 300 text messages and 20 megabytes of traffic, as well as 100 minutes of IP fees (add 17951 for long distance calls and 2.5 per minute). Then add 6 yuan for caller ID.

I also use this package, I hope it will be useful.
