Customizing text alert

So, to see if I understood correctly, the custom sound you chose for incoming texts doesn't play when you receive a text, but rather, when you send a text (you wrote "when the text is filled out and delivered")? That is quite odd. iOS allows you to customize the sound you hear when you receive a text, but when you send a text, it is always the same sound: "WooooOOOP!" (which plays immediately after the text is sent).

Here's an thread on the Apple Suppport Communities that states that the outgoing message tone is unconfigurable. The most you can do is silence it. So I'm clueless as to how your phone is making the sound when sending an outgoing text. (Again, assuming I understood your post correctly.)

 

Okay, so you have picked a text tone, for example:

(thumbnail, click to expand)

And when you go to your Contacts, pick any contact, tap on Edit, and scroll down to where it says "Text Tone", is it set to "Default"?

And still, you're not hearing the text tone you select?

ADDENDUM: If you are still in the same conversation screen that is currently taking place when a new text message comes in (from that same person), then yes, there is only one sound it will play... the "receive" version of the "WOOOOooooop" that you hear when you send a message. You only hear the custom text tone if you're not still in the same conversation with the person you're already texting, or if you're doing something else on your phone (checking your mail, for example). For example, text yourself at your own phone number, and don't navigate away from that screen. You will hear the same "WOOOOOoooooop" because you're already in that conversation, and NOT the custom text tone you selected.

 

I wish I could apply this to group chats
