Why did I send a short message and it disappeared?

Outbox is used to store messages that have not been successfully sent for the time being. There are many reasons that may lead to unsuccessful message sending, such as you.

At that time, the positioning signal was not good, and the contact of SIM card was not good. After those temporary problems are solved, you can find them in the outbox.

The text message I wanted to send before disappeared into the outbox after it was sent successfully. If your mobile phone is set to store sent short messages.

If you write a letter, the message you just sent will appear in the folder where the message has been sent.
