# SMS tutorials

Our tutorials are designed to help you leverage the power of the SMS REST API and SDKs in real world situations. They contain everything from helpful code snippets to web applications.

Note:
While these tutorials provide more real-world context and supporting material than some of our other guides, they are still intended for demonstrative purposes. In a production environment, you will have to modify any provided code samples to ensure that you maintain the security, efficacy, and stability of your solutions.
