If you are a T-Mobile customer and a user of the OneBusAway SMS interface, you've probably noticed that the service has stopped working in the last few days. The issue is that we use a free, ad-supported SMS service called Textmarks. T-Mobile recently raised the rates they charge services like Textmarks for sending and receiving SMS messages such that Textmarks can no longer afford to send free, ad-supported messages to T-Mobile customers.
I'm still trying to figure out what to do about this. OneBusAway has been lucky that we don't have any recurring monthly costs thanks to a generous donation of servers + hosting from UW CSE. Hopefully we can find some way to maintain SMS service that fits within the limits of our non-existent budget ; ) If anyone has any creative ideas or thoughts on potential solutions (SMS-email gateway, SMS via Twitter, etc) feel free to leave a comment.
