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.
On this page:
- T-Mobile and Google partner to enable T-Mobile customers with RCS UP 1.0 Android devices to get a RCS messaging experience while texting with Android users on other networks.
- Previously, RCS UP 1.0 messaging capabilities were only available while messaging with other T-Mobile customers.
Requirements for cross network RCS messages
- To experience RCS messaging features while texting with users on other networks, you need an Android smartphone with RCS Universal Profile 1.0 (UP 1.0) capabilities and be messaging with another T-Mobile user with a UP 1.0 device or with someone using chat features on the Messages app by Google.
- Generally, most Android smartphones from 2018 or newer have RCS UP 1.0 capabilities.
- T-Mobile users must be connected to the T-Mobile network or Wi-Fi with Wi-Fi calling.
- Both parties must be on Android devices.
- You can use the pre-installed messaging app on your devices to experience RCS UP 1.0 features while messaging with someone on other networks.
- To check if the messaging app is the default app: Press and hold on the current messaging app > Tap Advanced.
- If the app says it was installed from the Play Store, then it is not the default app.
RCS Universal Profile (UP 1.0)
With the UP 1.0 upgrade, the follow enhancements were made to Advance Messaging:

- Enhanced group chat features:
- 100 participants

What devices support Advanced Messaging?
You can check if a device has Advanced Messaging by visiting Tech specs > Connectivity for any device in Devices.
What happens if some participants of a group chat do not have a Universal Profile 1.0 capable device?
The group chat message capabilities will default to the device with the lowest denominator (MMS < Advanced Messaging < Advanced Messaging with UP 1.0). For example, if a new group chat is created and one of the receiving devices does not support Universal Profile 1.0, the group chat will be limited to a max of 20 participants and 10MB file transfers. All devices participating in the message must support the Universal Profile 1.0 software to enjoy the new messaging capabilities.
Are there visual indicators to know if someone else has the Universal Profile 1.0 update?
This can vary since each handset manufacturer’s native messaging app is different. When you’re in an RCS message with someone else, you may now see messages indicating “read” and you will be able to see that the other person is typing through the three dot typing indicator.
