(Isn't it good to see a virtual-monopoly tech giant get a dose of its own "You agreed to this when you signed-up to our UA" medicine, It must have been quite a shock for them to realise that they can't always get away doing whatever they like, whatever the law says.)
Strangely, as we're usually years behind with tech stuff, when obay started sending codes via text messages, it turned out that virtually all land-line phones in the UK can take text messages, which is why my bank, broker, Inland Revenue and other govt. depts. never have had any problems sending them to me. So there really isn't any reason that it can't be done, only that some company's don't want to offer alternatives.
