Adding voice and SMS capabilities to a mobile application is notoriously difficult for developers, which is why Plivo has stepped in with a simplified solution. The web-based application provides its users with DIY tools that they can use to integrate voice and SMS capabilities into their web and mobile applications using standard web languages.

Sign up for a Plivo account, and you can begin integrating voice and SMS features into your existing mobile app almost immediately. Follow the application’s step-by-step instructions to receive text-to-speech calls or make conference calls from a mobile app. You can also build digital phone menus and enable your users to send text messages to any phone number from their mobile devices.
