Link your customers to your app with SMS
Use the Number Insight and Developer API from Ruby code to validate, sanitize and determine the cost to call or message a number.
Programmable SMS is not just useful for one way notifications. When you combine outbound notifications with inbound messages you create chat-like interactions between your company and your customers.
Increase your application security
Replace your toll-free numbers (e.g. 800, 0800) with local geographical numbers that allow you to provide a better customer service. Users can make cheaper calls and you can offer location-sensitive information when they contact you.
