How to check if your mobile operator already supports RCS on iPhone

Apple released iOS 18 on Monday and one of the new features is support for Rich Communications Services (RCS) in the Messages app. However, RCS support must be enabled by each carrier. On a page on Apple’s website, you can find a list of carriers that already offer RCS support on the iPhone.

The company has updated its carrier support webpage to list which carriers support RCS on iPhone running iOS 18. RCS has worked with major U.S. carriers since day one, including AT&T, T-Mobile, and Verizon. Some carriers in Canada, Europe, and Asia also offer RCS support for iOS users.

RCS allows iPhone users to send rich messages with audio and larger media files to Android users. RCS also features read receipts, which were previously exclusive to iMessage and other instant messaging apps. Although RCS messages still have green bubbles, the Messages app displays the label “Text Message – RCS” in the conversation.

However, as we reported in June, carriers must work with Apple to provide an updated carrier package that enables RCS support for their customers with iPhones. During the iOS 18 beta phase, these updates could only be delivered with new iOS builds, but that is no longer necessary. Users can expect more carriers to add RCS support in the following months.

If you’ve already updated your iPhone to iOS 18, you can try enabling RCS by going to Settings > Apps > Messages. If you don’t see this option, your carrier probably doesn’t support RCS on iPhone yet.
