In a statement, T-Mobile revealed that its customers are responsible for sending an average of 613 million RCS messages per day in 2025. That figure includes messages from T-Mobile-owned MVNOs like Metro, as well as partner brands such as Mint Mobile and Google Fi.
That’s a sharp increase from just a few years ago. Back in 2020, T-Mobile and its MVNOs sent around 224.5 million RCS messages per day. In other words, daily RCS traffic on the network has nearly tripled in the past five years. While the company did note that MVNOs account for only a small portion of this activity, the numbers clearly establish T-Mobile as the biggest contributor to the RCS ecosystem in the US.
RCS, or Rich Communication Services, is designed to replace traditional SMS with a more capable and modern standard. It supports read receipts, typing indicators, higher quality image and video sharing, and the ability to message over Wi-Fi or mobile data. Over the past year, the format has gained even more traction thanks to Apple’s long-awaited decision to support RCS in its Messages application, finally bringing compatibility to text conversations between iOS and Android users.
