China Mobile sent 500 short messages with the student ID package. What package is this?

One-way charging package, in fact, discerning people know at a glance that this is not the one-way charging that ordinary people expected before, because only mobile "GSM" users can enjoy this discount. To put it bluntly, this so-called one-way charge is actually equivalent to a business package, which can only be enjoyed by advanced "condoms". Users can enjoy the "free answering" service while handling these business packages, but the related tariffs have also been adjusted to some extent. The adjusted package fee is not only not cheap, but also suspected of getting worse.
