My sms and mms vanish after I just sent it

[Chantelle Tasso]

I often write notes to myself on my phone for work references and this time I sent three and only one and three were sent one disappeared in between ...I really need to retrieve it please help me recover a vanished sent message.
This is not at all acceptable people use these phones for everything they do. Can't be losing work because it doesn't want to respond. And I can't have this continue...please please help.!

Welcome to Android Central! Which phone? Are you using the stock Messaging app? Were you sending a text message to yourself? If you want to write notes to yourself, I'd suggest using a note-taking app like Google Keep, rather than trying to text yourself.
