Advanced Messaging, also called Rich Communication Services (RCS), from T-Mobile is an enhanced messaging feature built into the manufacturer's messaging app on T-Mobile smartphones. RCS gives an improved messaging experience, allows larger multimedia file transfer, and shows interactive notifications when messages are being written, delivered, and read.

Advanced Messaging overview

In 2015, T-Mobile was the first to launch RCS to customers with Advanced Messaging capable devices. RCS-enabled devices can send RCS messages across networks to allow customers to connect with one another through a modern way of messaging.

Advanced Messaging requirements

Requirements for cross network RCS messages

  • To experience RCS messaging features while texting with users on other networks, you need an Android smartphone with Advanced Messaging capabilities. Generally, most Android smartphones from 2018 or newer have Advanced Messaging capabilities. 
  • Both parties must be on Android devices.
  • T-Mobile users must be connected to the T-Mobile network or Wi-Fi with Wi-Fi calling enabled.
  • You can use the pre-installed messaging app on your devices to experience Advanced Messaging features while messaging with someone on other networks. Their default Messaging app will be listed as an app on the bottom of the home screen unless they manually move it. You can change the default messaging app by selecting the new app at any time.
    • To check if the messaging app is the default app: Longpress on the current messaging app and select Advanced.
    • If the app states it was installed from the Play Store, then it is not the default app.

How to check if a device has Advanced Messaging

You can check if a device has Advanced Messaging by visiting Tech specs then Connectivity for any device in Devices.

  • Your device's default messaging app:
    • No particular status to check. It is auto-connected; Advanced Messaging will be supported as long as your recipient is capable of Advanced Messaging (RCS).
  • Messages by Google:
    • For some devices launched after 2/25/22, follow the steps to ensure the Chat Status is shown as “Connected”. Check Chat Status by going to Messages Home Screen, then select your account icon, then to Message Settings, then Chat features, and then Status.


What happens if some participants of a group chat do not have an Advanced Messaging capable device?

The group chat message capabilities will default to the device with the lowest denominator (MMS < Advanced Messaging). For example, if a new group chat is created and one of the receiving devices does not support Advanced Messaging, the group chat will be limited to a max of 20 participants and 10MB file transfers. All devices participating in the message must support Advanced Messaging to enjoy the new messaging capabilities.

Are there visual indicators to know if someone else has Advanced Messaging?

This can vary since each handset manufacturer’s native messaging app is different. When you’re in an RCS message with someone else, there may now be messages indicating “read” and you will be able to see that the other person is typing through the three dot typing indicator.

What does it mean when my Chat feature settings indicate “Chat features from Google provided by…”?

This indicates who is your Advanced Messaging provider on Messages by Google. You can check this by going to your Messages Home Screen, then select your account icon, then Message Settings, then Chat features, and then scroll to the bottom of the screen.

On devices that state, “Chat features from Google provided by Jibe Mobile.”, this means Google is the Advanced Messaging provider for Messages by Google on the device.

On devices that state, “Chat features from Google powered by T-Mobile.”, this means T-Mobile is the Advanced Messaging provider for Messages by Google on the device.
