Why doesn't texting work with other apps?

[AC Question]

Texting doesn't work with other apps.

So I decided to download a texting app for more customisation.
When I wanted to send a text, doesn't matter what app I tried, it wouldn't send.
I tried searching for an answer but I couldn't find anything.
(I'm Belgian so my provider is also Belgian in case that would be a problem)
My phone is a Huawei ascend G6 , and android Jelly bean 4.3.
Can anyone help please?

Welcome to Android Central. I can't think of anything offhand to suggest. You can email the developer and explain the issue. It may be a coding problem in the app.

Hi, I think the problem is in the phone. If this message is sent to the stands reset to factory settings. If it is not possible to update the firmware is worth.
