Hi Susan I am not an iPhone user but from your question, it is hard to know where to start. Perhaps you should tell us how much you know about the iPhone and Voice Over. Can you turn on Voice Over independently? Do you know about the different typing modes for sending a text message? What do you know about the Rota, have you any apps? Have you explored the Settings for the various apps? Will your preference be to use the virtual keyboard or a bluetooth keyboard Etc. Just put out some ideas to get you started.
