How to enable RCS on your phone
RCS (Rich Communication Services) is a modern messaging standard designed to upgrade traditional SMS and MMS. It enables richer messaging features such as read receipts, typing indicators, high-resolution media sharing, and improved group chats.
Most modern smartphones support RCS, and it is often enabled automatically if your device, operating system, and mobile carrier support it. However, users can also manually enable RCS through their phone settings.
In this guide, we explain how to enable RCS on both iPhone and Android devices, along with common requirements and troubleshooting tips.

RCS is a messaging protocol that enhances traditional text messaging by adding features commonly found in modern messaging apps.
Typical RCS features include:

RCS works inside the native messaging apps on smartphones, such as the Apple Messages app on iPhone or Google Messages on Android.
