How do Anhui Mobile users query the number of SMS messages sent?

The network is mobile and Unicom, and PHS sends each other; The network is sent from mobile to mobile, and there are 300 short messages in Monternet. For example, sending short messages to check the number of short messages, and replying to Fetion is also Monternet short messages. I don't know whether the 300 messages you sent came from 200 networks plus 100 networks, or whether they were all in the network. Anyway, the 500 messages I send out in a month are all within the network (including Monternet SMS).
