Try sending a text (SMS) to a landline. At the moment, the voice that reads out the text on BT sounds like Tom Baker, arguably the best Dr Who ever. I sent the following to my Father-in-law: "This is the Doctor. I'm sorry I can't visit you next week but maybe I can try yesterday. I'll be travelling on the third vortex if you need to get in touch. K9?! K9...." It was wasted on him. He spent an hour doing battle with a call centre in India, explaining that he didn't have a text service for his telephone and demanding to speak to someone in England!
