"prices for individual text messages on pay-as-you-go plans have quadrupled from an average of 5 cents to 20 cents"
Really? In the UK they've stayed static at about 10-12p for at least ten years (for a 'standard' text on a PAYG plan, assuming no extras which give you reduced rates on texts to certain people etc.). We're also not charged for receiving standard texts (there can be a charge for premium ones, but not everyone can send those).
Yes. In the UK, as with most of the world, we embraced text messaging (12years ago I was txting every day). In the USA, this took a lot longer, with phones often note supporting SMS.
