How can I send an SMS from the Web (in the USA) to a brazilian cell phone in Brazil?

Question

It doesn't have to be free, but has to be reliable. I also need to be able to receive a response back from the person. Does any such service exist?

Additional Details

p.s. I am not looking a "FREE" SMS service, many show up in Google but mostly they appear to be scams.
