If you have a US passport, you should still be able to get a 30-day SIM, but I'm not sure. As for getting it continuously, I know several people who have gone back to the airport to return and re-rent the same SIM.

If you're trying to save money, and are willing to spend more time and get not-unlimited data, you can get the monthly plans from Olleh directly. It requires going in to a store, and a lot of confusion.

On another note, since you do have an ARC, you might be better off leveraging that to obtain "normal" cell-phone plans. You'll have to do more research on that yourself.
