I suspect your problem here is the message centre number, this needs to be +447785016005.

Take a look at device guides and follow the information provided on this link Device Guides

Your message settings.   Try synchronising to your Apple account and download all the correct carrier settings.

there is nothing in settings about message centre number or synchronising to apple account or downloading carrier settings.
