@kaanaksoy81 well said, SMS and chat may seem similar, but they’re actually quite different means of communication and can serve entirely different purposes. Each has its own strengths and limitations, and which one is best suited for your app will depend on what you need.

And while chat typically offers more functionality and flexibility, it comes with constraints such as needing to be connected to the Internet. I would suggest other chat provider Like MirrorFly
