I've used clickatell a lot in the past (circa 2005-2007). I'd recommend them. Be prepared to fax them details to confirm some things. One minor frustration with them is that they have a division between their API account and their desktop messenger. It sounds like you'll be using the API first. But you cannot then use excess credits for any personal sideline messaging using their client.
