Sinch Mobile SDK

A Mobile SDK to add voice and messaging to your apps

With the Sinch Mobile SDK, integrate calling and messaging to your iOS and Android apps. Build your app, integrate the Mobile SDK and let your users start connecting with each other via voice calling and messaging.

Features of the Mobile SDK

Multiple Devices

Our Mobile SDK is available for iOS and Android and also JavaScript and REST API and the Sinch platform runs in the cloud. Just integrate the SDK into your app and start connecting the different devices your app supports, all with the same backbone.

Great Documentation

Our developers have written a fantastic, in-depth documentation section to help you integrate our Mobile SDK into your apps as easily as possible. Read our user guide and API documentation to see how simple Sinch is to integrate.

Hassle-free and Scalable

Sinch is designed to grow with you. After integrating our Mobile SDK, you can continue to develop your app whilst we take care of the backend and just pay as you grow. Take a look at our pricing to see how you can use Sinch today.

Safe, Secure And Anonymous

The Sinch Mobile SDK allows you to message and make anonymous calling to protect your users. Plus, using the latest SSL and HTTPS technologies, Sinch makes sure that your app to phone calls are secure and private.

How it Works

id<SINCallClient> callClient = [sinchClient callClient];
[callClient callUserWithId:@"John"];
CallClient callClient = sinchClient.getCallClient();
Call call = callClient.callUser("John");
