RCS messaging has seen a significant surge in popularity, especially in Western markets. With over a billion users globally, this growth is largely attributed to Apple’s integration of RCS compatibility in iOS 18. While iOS 18 initially offered limited carrier support for RCS messaging with Android, Apple has recently broadened its compatibility, making RCS accessible to a wider audience.
Supported Carriers for RCS on iOS 18
Apple’s updated support page reveals a growing list of carriers now supporting RCS messaging on iPhones:
- AT&T
- C Spire
- Consumer Cellular
- Cricket
- FirstNet
- H20 Wireless
- Metro by T-Mobile
- PureTalk
- Red Pocket
- Spectrum
- T-Mobile USA
- TracFone/Straight Talk
- US Cellular
- Verizon Wireless
- Visible
- Xfinity Mobile
While this list is extensive, it’s not exhaustive. Carriers like Boost Mobile offer RCS support but are currently excluded from Apple’s official list. Nevertheless, this provides a valuable starting point for users seeking RCS-compatible carriers.
Notable Absences and Google Fi’s Stance
Despite the expanded support, some key players are still missing. Notably, Google Fi remains absent. Google previously stated that enabling RCS for iPhone users rested solely with Apple. Currently, Google Fi doesn’t facilitate RCS communication between Google and iPhone users.

Understanding RCS Messaging
RCS messaging can be viewed as a modern upgrade to traditional SMS and MMS. It offers features similar to Apple’s iMessage, including read receipts, high-resolution media sharing without compression, and enhanced messaging capabilities.
RCS vs. iMessage: Key Differences
It’s important to understand that RCS isn’t a direct replacement for iMessage. While it improves upon SMS, iMessage boasts unique features not found in either SMS or RCS. However, RCS represents a significant advancement in messaging technology, offering a superior alternative to outdated SMS.
Conclusion: The Future of RCS
The increasing carrier support for RCS messaging on iOS 18 is a promising sign. This expansion allows more users to transition away from SMS and embrace the benefits of rich communication services. The continued growth and adoption of RCS promise a more engaging and feature-rich messaging experience for users across different platforms.
