How to deal with the situation of sending fetion and receiving fetion short messages at the same time?

At the same time, we need to know the characteristics of the latest version of Fetion: now the latest version of Fetion and the communication version have more "messages" when sending information than the previous version; Click the button of the "SMS" switch, and the yellow bubble on the left is the message-that is, the message, which can only be viewed in the client; Then click on the envelope to the right of the yellow bubble, which is a short message-when the client is offline, others will send it to you as a short message. In order to receive the message from Fetion in time, the receiver needs a pc webpage first, and the mobile phone is set to receive the short message from Fetion. If one of these items is not set, it is likely that the client will not receive the short message of Fetion offline (when the sender sends it, the system will prompt the user not to receive the short message of Fetion, so it cannot be sent). Secondly, when sending content, the sender should carefully identify whether the client is online (the new version of Fetion can't see the online location of friends, but can only see an inconspicuous prompt-what will be prompted at the top of the ——PC, and the mobile phone must see the user online in the friend profile mode). If the client is online, you can send content in message mode. If the client is not online, the sender must switch to SMS mode, and the receiver will receive the prompt in time, otherwise it will not be received. However, if the friend client is online but sends the content by SMS, the friend client and Fetion SMS will receive the message at the same time.
