My package allows me to send 200 text messages per month. I checked the number of text messages sent: 25 within the network, more than 300 and 0 outside the network. How is the fee charged?

What does it mean to send 200 text messages easily? Within the network, text messages are sent to the same type of card. For example: yours is a mobile card, and the card of the recipient of the text message you send is also a mobile card. Outside the network, that is, you send text messages to China Unicom or China Telecom. The package charges are different, so check what your card stipulates! 10086 completely free
