RCS (Rich Communication Services) is a messaging standard that enhances traditional SMS and MMS with features like read receipts, typing indicators, higher-quality images, and videos. Apple's Messages app now supports RCS in iOS 18, improving the communication experience between Android and iOS users.
To activate RCS in the iOS 18 beta, follow these steps: 1) Ensure your iPhone is running the latest iOS 18 developer beta. 2) Go to Settings > Apps > Messages. 3) Look for the RCS toggle and switch it on. Note that the toggle may not be visible if your carrier doesn't support RCS or hasn't updated its network bundle for iOS 18. Currently, RCS is only available to those in the US with carriers that support it, such as T-Mobile, AT&T, and Verizon.
Currently, RCS support on Apple devices is limited to select US carriers, including AT&T, T-Mobile, and Verizon1. This is based on the information available in the iOS 18 beta, and the support is expected to expand to other carriers and regions as the stable version of iOS 18 gets closer to its release in September 2024.
