can't text shortcodes

[N246]

I wonder if anyone can help me with this issue. I am unable to text shortcodes such as competition numbers. Even texts to my network provider do not send. I have a normal s7, I think this may be something to do with the permissions because I think I denied something when I used text messaging for the first time. My network provider said there was a bar on the phone which they removed but text messages are still not sending. Does anyone know what this could be I have reset all app permissions but this hasn't worked. Any help with this would be greatly appreciated. Thanks

Have you reset the app permissions of the SMS app?
