Millions of iPhone users have already been using RCS, they just don't know it
Why have millions of iPhone users in Japan been using RCS without realizing it?
Millions of iPhone users in Japan have been using RCS without realizing it due to the downloadable +Message app created by the three major Japanese carriers: KDDI, NTT DOCOMO, and SoftBank. The +Message app is built on the GSMA's RCS standards, enabling a feature-rich, secure alternative to SMS for person-to-person communications. It supports many features enabled by RCS, such as read receipts, higher quality media sharing, file sharing, group messaging, and much higher character limits. The app is preloaded on many Android smartphones sold in Japan but is also available on iPhones through the Apple App Store. The popularity of the +Message app in Japan has led to several million iPhone users in the country sending or receiving an RCS message at least once.

What is RCS and how does it improve upon traditional SMS/MMS messaging?
RCS, or Rich Communication Services, is an advanced messaging protocol designed to enhance and improve traditional SMS (Short Message Service) and MMS (Multimedia Messaging Service) text messaging. It offers several key features that make it a more interactive and feature-rich messaging experience, similar to popular messaging apps like WhatsApp or iMessage.
Here are some ways RCS improves upon traditional SMS/MMS messaging:
-
Enhanced Media Sharing: RCS supports sending high-resolution images, videos, and audio clips, making it more versatile for multimedia content.
-
Read Receipts and Typing Indicators: Similar to instant messaging apps, RCS shows when a message has been delivered, read, and when the other person is typing a response.
-
Group Chat Improvements: RCS enables better group chat functionality with the ability to name groups, add or remove participants, and share larger group sizes than traditional SMS.
-
Larger Character Limit: Traditional SMS has a character limit of 160 characters, while RCS supports longer messages, allowing users to send more extended texts in a single message4.
-
Presence Information: RCS can show whether a contact is online, offline, or currently available, enhancing the real-time communication experience4.
-
Secure Communication: RCS messages are encrypted, providing higher security for conversations.
To use RCS, both the sender and the recipient need RCS support enabled on their devices, and their mobile carriers must also support RCS. Some Android devices come with native RCS support through the device's default messaging app, while others may require you to use specific messaging apps provided by the carrier.
