It's not novel, really. People have been using other operators around the world since shortly after the iPhone release. I can pay less than $23 and receive as many calls as I want for a year on my iPhone. That's not in the US though. I have a SIM card for one country where I need to pay about $1.5 a month minimum if I don't spend at least $9 worth a month. It's pre paid. Text messages are ~ US 3.5 cents each. About 8 cents a minute for outgoing calls. You don't pay for incoming calls. Data is about 90 cents per MB. What kind of functionality do you think is missing?
