The text message I sent has appeared in the previous information bar. Did the other party receive it?

When the message you sent appears in your message bar, it means that you have finished sending the message, but the other party may not have received the message.

There is also a sending process for short messages to appear in the information bar. In most message bars, the words "successful sending" will appear when sending the message, so whether the other party receives the message does not necessarily depend on whether it appears in your message bar, but on the commitment and network speed.
