Apple is taking another step toward modernizing everyday texting on iPhone, with iOS 26.5 bringing expanded support for RCS messaging inside the built-in Messages app. While this is an important upgrade for anyone who regularly texts Android users, Apple’s RCS rollout is still in beta, which means there are a few limitations iPhone owners should know about before expecting a fully seamless experience.
For now, iPhone RCS messaging only works under specific conditions. The biggest restriction is on the Android side: RCS will only function if the person you’re texting is using the latest version of the Google Messages app that supports RCS communication with an iPhone. If the recipient is using an older app version or a different messaging app that doesn’t support this compatibility, conversations may fall back to traditional SMS or MMS.
Carrier support is the other major factor. At the moment, RCS on iPhone is only available through selected network operators. In the United States, the supported carriers currently include AT&T, Boost Mobile, C Spire, Consumer Cellular, Cox Mobile, Cricket, Family Mobile, FirstNet, H20, Metro, PureTalk, Red Pocket, Spectrum, T-Mobile, Total, TracFone, Ultra Mobile, US Cellular, Verizon, Visible, and Xfinity. If your carrier isn’t on that list, you may not see RCS options appear yet, even after updating.
The good news is that iOS 26.5 doesn’t require any extra downloads or separate apps to get started. Apple has built RCS directly into Messages, the same app iPhone users already rely on for SMS, MMS, and iMessage. That means you don’t have to change how you text day to day—support is handled in the background, depending on your carrier and who you’re messaging.
In addition to messaging updates, iOS 26.5 also introduces a new feature for users in the European Union: the ability to forward Live Activities to supported accessory products. This expansion makes Live Activities more useful beyond the iPhone screen, allowing compatible accessories to display ongoing, real-time information.
Apple hasn’t confirmed in the release notes whether iOS 26.5 also delivers improved support for third-party smartwatches, something many users have been waiting for. For now, that remains an open question, but the Live Activities forwarding feature suggests Apple is continuing to explore broader accessory integration.
With iOS 26.5, Apple is clearly moving toward a better cross-platform messaging experience and adding more flexibility to Live Activities—just keep in mind that RCS on iPhone is still a work in progress, and availability depends heavily on both your carrier and the recipient’s setup.
