To send text messages from your home phone, you will need a text compatible phone and a compatible telephone line. To view text messages on your text compatible phone, you will also need to subscribe to the BT Caller Display service. If you don't subscribe, you will receive text messages as voice messages. If you haven't registered for the service, you will also receive text messages as voice messages.

Which I admit is ambiguous but appears to say that you need a text compatible phone to read messages on the screen.
