Enter your phone number and receive an SMS

  • What's Happening
  • Technical Version

When you click “Send SMS,” a request is sent to Twilio to deliver an SMS to the provided phone number. The server logic determines the weather forecast for San Francisco and sends a related message and graphic to the phone number.

When you click "Send SMS", an AJAX request is made that, in turn, triggers a server-side HTTP request to Twilio, which provides a number to SMS, as well as a URL of the photo to be delivered. Image media is automatically transcoded as needed to adapt to carriers and handsets.
