RCS Messaging on iPhone — Full List of Supported US Carriers

Apple’s iOS 18 introduced RCS (Rich Communication Services) messaging, bridging the gap between iPhone and Android users.

Unlike traditional SMS, RCS offers features like read receipts, typing indicators, and support for larger files. Initially, only major carriers like AT&T, Verizon, and T-Mobile supported RCS.

However, Apple has since expanded compatibility to include a variety of smaller carriers.

Here’s the current list of supported US carriers:

• AT&T
• Boost Mobile (requires iOS 18.2)
• C Spire
• Consumer Cellular
• Cricket
• FirstNet
• H2O Wireless
• Metro by T-Mobile
• PureTalk
• Red Pocket
• Spectrum Mobile
• T-Mobile
• TracFone / Straight Talk
• US Cellular
• Verizon
• Visible
• Xfinity Mobile

This expanded list now includes many MVNOs (mobile virtual network operators), increasing access to RCS messaging.

However, notable exceptions remain, such as Mint Mobile and Ultra Mobile, despite their acquisition by T-Mobile earlier this year.

What’s Next?

As Apple continues to update iOS 18, more carriers may join the list. RCS messaging promises a better texting experience, but users on unsupported carriers will need to wait for further updates.
