Hello WanSyo,
Thanks for that info and for choosing the Apple Support Communities. If I understand correctly, you are getting an error message about messages on your iPhone, even after checking with your carrier. To help with this, please follow the relevant steps in this Apple resource and then contact Apple if you need any further assistance.
If you can't send or receive messages on your iPhone, iPad, or iPod touch
Cheers!
