Is there an extra charge for inserting dynamic small expressions into text messages?

Not necessarily. . For example, a small dynamic expression in a mobile phone is usually the capacity of four Chinese characters in a mobile phone, so what the other party receives is that the expression corresponding to his mobile phone may be different from that sent by your mobile phone. If you laugh at QQ expression (the expression that comes with your mobile phone), then what the other person receives in his mobile phone is the expression that comes with it. (Laughter) If it's a smiling expression in a black-and-white picture, it's usually the size of 66 Chinese characters in a moment, then he receives this, and 70 Chinese characters count as a short message.

Generally speaking, there is no charge for accepting MMS. If the picture capacity is greater than a certain standard, it is necessary to collect money. It is generally no problem to charge extra capacity.
