Im in Australia right now and don't have a option for an sms gateway for text notification. If you are in the same boat with no sms gateway try Boxcar. They give you an email address that you can have HM send an email to and get a near instant push notification to your phone. If anyone has anything better let me know. I was originally trying to do something with Google Voice but surprisingly they don't have a sms gateway. This is for iPhone btw.
