It seems like short-term messaging is coming to an end. I recommend using email instead. Short messages cost around 0.1 yuan each, and even the minimum price is likely 0.5 yuan. If you want to negotiate, you can also get them for 0.045 yuan each. For larger volumes, prices range from 0.2 yuan to 1 yuan. The main factors are volume and delivery rate. It's not feasible to handle large quantities of "grasshopper legs."
