Mobile phone fetion charging problem

Simply put, as long as the other party is online, there is no charge for sending messages to the other party, similar to QQ. If the other party is offline, the information sent will be sent as ordinary SMS, which means that if you send SMS for free, there is no charge. Of course, if you charge for SMS, the normal SMS fee will be deducted. As for the question you mentioned, the message will directly switch to the short message state, the other party will display your mobile phone number, and the Fetion message will display the Fetion signal. There is no difference between the other two.
