We've been playing with text messaging (SMS) technology at Goose Networks since our early experiments with real-time ridesharing back in 2006. With SMS in our ‘Corporate DNA,’ we were all the more excited to roll out our 'SMS Alerts' feature to clients in late 2009.
With SMS alerts, clients can set up distribution lists (d-lists) for specific shuttle/transit routes (i.e. 'Red Line Alerts') or other groups (i.e. 'General Commuter Alerts'). Users register their mobile phones to receive alerts from one or more list, and program administrators can send out alerts at their convenience via the Admin Control Panel's 'SMS Campaigns' tool.

We like to think that we've kept the feature simple from end-to-end. This was important to us, since things are actually fairly complicated under the hood. What could be complicated about sending text messages? For starters, imagine that you're offering an SMS alerts program for the Red Bus line, and one of your subscribers decides to cancel his cell phone plan and switch to a different operator (with a different phone number). When he does so, his old number will eventually get recycled and given to a new cell phone customer. That person doesn't expect to receive SMS alerts about the Red Line, and will probably consider any such alerts unwanted SPAM. Luckily for you, we've put systems in place to make such an outcome impossible. By working diligently with each of the major US mobile phone operators (Verizon, AT&T, Sprint, etc.), we can track when phone numbers get taken offline or recycled, and automatically unsubscribe them from any our of d-lists before they receive unwanted campaign messages.
While SMS is considerably more complex than email, we've done to our best to hide that complexity behind an extremely simple, intuitive tool; it is our hope that we've been able to make sending an SMS alert as simple as sending an email campaign via the Goose Mailing List manager.
If you're interested in offering SMS Alerts to your riders, please contact us to set up a live demo -- we'd love to show you this tool in action.
