I don't call often, but I send more messages. Which is better, mobile or Unicom?

The average student who moves is always moving. I am hehe.

Mobile "M-Zone" sends 400 short messages every month, which of course refers to mobile users. Although Unicom also sends short messages, it is more expensive to send them to mobile users, and now it is used more frequently.

So I said it would be cheaper to move.
