Send text messages with "you" software. If I have wifi and the other party doesn't, how do I charge? Is it accepted by both parties?

Standard answer:

8. When your friends are not online, do you spend traffic or text messages? If friends are online, they can send messages to each other for free, and only spend a little traffic; If the friend is not online, the information sent to TA will go to the SMS channel and be sent to the friend's mobile phone in the form of ordinary SMS, and the fee will be charged by the operator.

In other words, both sides have "you" and both sides are networked. Only in this way can they be free. Without one of these conditions, neither can be free.
