Ok to send the ticket outside the US, what countries do you support? the number to be entered in the form should be "++ [country code] number" right? If the tickets are not delivered to the phone, does the user get an email saying so, or even just having the form provide a status report straight away.
Actually we only work in the US right now. We were using clickatell but they are going through a huge audit right now. As soon as clickatell gets their act together we will support other countries. Shoot us a email and I will let you know when we have it working again.
