iOS 18.4 Beta Brings RCS Messaging to Google Fi and Other T-Mobile MVNOs

Apple has released the iOS 18.4 beta, which includes support for RCS (Rich Communication Services) on Google Fi. This update allows iPhone users on Google Fi to use advanced messaging features like high-quality images and group chat. The RCS toggle can be found in Settings > Apps > Messages, and the activation process may take a moment. Additionally, this update enhances support for other MVNOs (Mobile Virtual Network Operators) using T-Mobile’s network. iOS 18.4 is expected to release as a stable build in April, following a few more beta releases.
