Hello. I have the same issue? I have set a time but it is not sending a message. I have contacted Sony about this issue. They told me that this funcion is depends on the operator. But my brother has the same operator as me and he is able to send scheduled messages using Samsung device. After that I have contacted Sony again and they told me that they do not have this funciont in their software! Joke! If it was possible I'd gladly sent the screenshot to them. If you open a conversation, in the top right corner, press ... and you'll see an option - schedule a message. But it's not working! Does anyone found a solution?
Please just don't tell me to download third party apps. I want to use pre installed app.
