As long as there is one for MMS you should be able to text. So if you see one like MMS Transport or MMS Client that should be all you need. Are you on a pay as you go plan or monthly? Please read below for info from Vodafone. Since everything else works on device it should be something on their end. Also,did you try to send a text to yourself?

It is normally stored under message settings on your phone.
The quickstarts in Phone help will show you how to do this.
The message centre number should read +447785016005.
If this is not shown you will need to delete the current entry and enter this number.
